In this interlocutory appeal, the United States challenges the district court’s suppression of statements made by Jason Bervaldi and of physical evidence seized from his residence. This appeal presents two questions: whether the law enforcement agents who arrested Bervaldi and seized the evidence had a reasonable belief at the time of entering his residence that it was the dwelling of the subject of an arrest warrant they were attempting to execute; and whether they had a reasonable belief that this subject would be present there. For the reasons stated below, we conclude that they did have such reasonable beliefs and, accordingly, reverse and remand.
I. BACKGROUND
At approximately 6:00 a.m. on March 10, 1998, Officers Wilfredo Abascal and Rafael Masferrer and several other officers approached the house at 3621 S.W. 129th Avenue (“129th Avenue”), in Miami, Florida, to execute an arrest warrant for Bennett Deridder. The officers observed two trucks and a boat trailer parked in the driveway. The officers were wearing raid jackets featuring the word “police” on the front and back. The sky was dark and a single exterior light shone about two feet from the front door.
Officer Abascal knocked hard on the front door for about ten minutes without response. As the officers were turning away to check the license tags on the parked vehicles, the front door opened about one foot. Officer Abascal observed the left side of a barefoot, bare-chested man standing at the door wearing shorts, but could not, given the lighting, clearly see the man’s features. Officer Abascal observed, however, that the man had the same height, stocky build, and complexion as Deridder, 1 and that the hair on the man’s head was shaved while Deridder had last been observed with a full head of hair. Officer Abascal also observed that the man’s left hand was behind his back and thought that he might be armed.
Officer Abascal announced that they were police. The man slammed the door shut. The officers kicked the door down, entered the house, and caught the man within ten to twenty feet of the entrance. A cocked, but unloaded 9 millimeter pistol was found resting on a gym bag ten feet to the right of the door. Officers Abascal and Masferrer quickly realized that the man that they held was not Deridder. The officers, performed a protective sweep of the house believing that Deridder or others might be in the house. During this sweep, the officers noticed a very strong smell of marijuana coming from the kitchen.
The officers discovered that the apprehended man was Jason Bervaldi. After Bervaldi was advised of his Miranda rights and indicated he understood, the officers asked him whether marijuana was *1259 in the house. Bervaldi showed the officers marijuana stored in the kitchen cupboard. Bervaldi orally consented to a search, but would not sign a written consent form. The officers did not immediately search beyond the initial protective sweep. Instead, some officers went to get a search warrant. When they returned with a search warrant around 5:00 p.m., a search was conducted that resulted in the discovery and seizure of 60 pounds of marijuana stored in kitchen cupboards, 17 sealed baggies of marijuana, 1 kilogram of cocaine, 3 bags of cocaine cutting agent, 1 Ohaus digital scale, 1 Nexus scale, 1 cellular phone ESN reader, various cellular phones and accessories, 1 Cobray MAC-119 mm semiautomatic pistol, 1 Browning rifle with ammunition, $53,483 in U.S. currency, 1 1998 Ford pickup truck, 1 1997 Contender boat, 1 jet ski, 1 motorcycle, 1 Rolex watch, 1 large machine press, and 1 wooden mold. Although Bervaldi was kept in custody throughout the day at his residence, he was not formally arrested until later that evening.
On March 20, 1998, a federal grand jury sitting in Miami, Florida, returned a three-count indictment charging Bervaldi with knowingly possessing cocaine with intent to distribute, in violation of 21 U.S.C. § 841(a)(1), knowingly possessing marijuana with the intent to distribute, in violation of 21 U.S.C. § 841(a)(1), and knowingly and intentionally possessing and receiving a firearm which had the importer and manufacturer’s serial number removed, obliterated, and altered, in violation of 18 U.S.C. § 922(k). On May 1,1998, Bervaldi filed motions to suppress his statements and the physical evidence seized on March 10, 1998, on Fourth Amendment grounds.
On July 2 and 15, a magistrate judge conducted an evidentiary hearing on the motions. At this hearing, Daniel Maho-ney, a special agent with the Drug Enforcement Administration (“DEA”), testified that Bennett Deridder was identified in June 1997 as a person involved in a drug operation based on telephone calls inter-eepted by lawful wire taps. Mahoney indicated that Officers Abascal and Masferrer assisted in identifying Deridder’s residence. In particular, these officers identified a vehicle that Deridder was driving based on a traffic citation and determined that that vehicle, a red Chevy truck, was registered- to 3621 S.W. 129th Avenue in the name of Betty Spatten. Mahoney further explained that on June 27, 1997, these two officers observed the vehicle leaving this residence, followed the vehicle, and then spoke with the driver, Deridder.
Abascal testified that on June 27, 1997, he and Masferrer attempted to get a voice identification on Deridder to link the wiretap evidence to Deridder. Consistent with Mahoney’s explanation, Abascal explained that they sought Deridder at the 129th Avenue address after checking Metro-Dade computer records for traffic tickets which revealed that on June 4, 1997, Der-idder had received a traffic citation while driving a red pickup Chevy truck with tag number VAW56Y. Although the traffic citation record listed 4406 S.W. 132nd Place (“132nd Place”) as Deridder’s address, they discovered that this truck was registered in Betty Spatten’s name to the 129th Avenue address. On June 27, 1998, they observed Deridder come out of 3621 S.W. 129th Avenue residence, get in the same red pickup truck, and drive to a “food stop.” When Deridder stopped at the food stop, Abascal and Masferrer approached him, identified themselves, and had a brief conversation with him. Abascal asked Deridder where he lived. Derid-der provided the 129th Avenue address and what he identified as his parents’ address, the 132nd Place address. Abascal explained that Deridder provided two addresses, “one for his parents, and one for his residence.”
Masferrer’s testimony was consistent with Abascal’s testimony. Masferrer also reported that Deridder gave the 129th Avenue address as his residence and the 132nd Place address as his parents’ address. 2
*1260 At the hearing, the Government also adduced evidence concerning queries of computer systems. Mahoney testified that he used Autotrac, a compilation of several databases, ranging from highway safety to corporations and real estate, to acquire information on Deridder. On June 26, 1997, Mahoney ran the first Autotrac query on Bennett Deridder. The printout of this query, which was admitted into evidence, included the following:
Known Subject Addresses
DE C-85/MAR-97 —4406 SW 132 PL, MIAMI FL 33175
Mahoney explained that this indicated that some type of information found in one of the databases contained in Autotrac linked Deridder to that address from December 1985 to March 1997. Mahoney also explained that the printout listed Phillip Der-idder, Bennett Deridder’s father, as a possible relative and listed
Mahoney also testified about a computer check of Flight Equipment, Inc., conducted on August 20, 1997. The printout of this check, which was admitted in evidence, included:

Mahoney also testified about a second Autotrac check of Deridder conducted on February 4, 1998. The printout of this check, which was admitted into evidence, included:

This printout also indicated that a 1995 homemade trailer, with a tag which expired in September 1998, was registered to the 132nd Place address in Bennett Derid-der’s name. There was no information on this printout after June of 1997 showing any other address for Bennett Deridder.
Mahoney also described an Information America printout, a credit report, that was dated February 9, 1998. For Deridder, it listed the 132nd Place address as well as some other addresses. Likewise, driver’s license records and arrest records that Mahoney checked listed the 132nd Place as Deridder’s address.
Mahoney testified that he gave the arresting officers the 129th Avenue address and the 132nd Place address for Deridder. He explained that he gave them the 129th Avenue address because it was “obvious” to the investigators that Deridder was only using his parents’ address, 132nd Place, as a “straw address” for records and was actually residing elsewhere. The parents’ address was provided because, if Deridder needed to be tracked down, speaking to his parents to seek his whereabouts would be part of the process.
Mahoney explained that the arrest warrant listed 132nd Place as Deridder’s last known address because that is the permanent residence of his family, who would be contacted if Deridder needed to be located. He explained that 129th Avenue would be the first place to check for Deridder because it is where he resided.
Mahoney also testified that he observed a red Chevy pickup with tag VAW56Y at the 3621 S.W. 129th Avenue address on August 20, 1997. A check revealed that it was registered to Betty Spatten at that address.
Bervaldi adduced several pieces of evidence to show that Deridder did not reside at 129th Avenue on March 10,1998. Brian McGuinness, a private investigator, testified about Autotrac. He explained that Autotrac is a “compilation of public record data that comes from a variety of sources” and that it is not always accurate. He also testified that Agent Mahoney could have run a “Dossier” search, which would have been more expansive than the searches Mahoney ran, but that there was “not very much” difference between these two types of searches. Bervaldi introduced into evidence a Dossier search of the 129th Avenue address, which indicated that Bervaldi registered a vehicle there in January 1998. Mahoney testified that he did not run a Dossier search because it generally does not have investigative value but instead just lists trails of information about evéry possible individual who lived at a residence.
*1262 Second, McGuinness testified about several records he acquired which indicated that Deridder moved from the 129th Avenue residence around the beginning of 1998. First, a warranty deed, dated February 17, 1998, which indicated that Marcella and Phillip Deridder sold the property to Jason Bervaldi, was recorded in the public records on .March 5, 1998. Florida Power & Light records, acquired by subpoena, indicated that Beatriz Ramos was a customer at the 129th Avenue address beginning on December 30, 1997, and Felipe Deridder was a customer from May 14, 1996, to December 30, 1997. Miami-Dade Water & Sewer records, also acquired by subpoena, indicated that service for the 129th Avenue address was in the name of Marcella Deridder from May 3, 1996, to January 5, 1998, and in the name of Beatriz Ramos starting on December 30, 1997. Likewise, BellSouth Telecommunication records, again acquired by subpoena, indicated that service’ to the 129th Avenue address was established by Ramos on January 5,1998. 3
Bervaldi also introduced the affidavit of Donald Brooks, a part-time carpenter, which indicated Brooks did some repair work-on the 129th Avenue residence in the last part of January and early February of-1998 and that, to the best of Brooks’ recollection, there was no for sale sign on the property at that time. Pedro Molina, a landscaper who provided service to the 129th Avenue address, testified that he observed a for. sale sign in the summer and fall of 1997, but when he went to the address on December 22, he did not see the sign. Abascal testified that he saw a for sale sign in front of the house on June 27, 1997, and on the morning of March 10, 1998. Masferrer testified that he recalled seeing a for sale sign prior to March 10, 1998, but could not recall if he saw one that morning. Pictures taken of the house on March 10, 1998, do not show a for sale sign. 4
On July 23, 1998, the magistrate issued a report and recommendation. In particular, the magistrate judge concluded that the officers could not have reasonably believed that Deridder resided at the 129th Avenue house on March 10, 1998, but that, had they reasonably believed that this was his residence, then they could have reasonably believed that Deridder was at the house when they entered it. The magistrate judge recommended that the motions to suppress be granted. On August 18, 1998, the district court adopted the magistrate judge’s report and recommendation and granted the motions. The United States appeals.
II. DISCUSSION
Because rulings on motions to suppress involve mixed questions of fact and law, we review the district court’s factual findings for clear error, and its application of the law to the facts
de novo. See United States v. Magluta,
Although searches and seizures inside a home without a search warrant are presumptively unreasonable, in
Payton
*1263
v. New York,
We examine first whether the officers had “a reasonable belief’ that 129th Avenue was Deridder’s dwelling when they entered on the morning of March 10, 1998. Despite the Autotrac reports and driver’s license records indicating that Deridder’s address was 132nd Place, there was strong evidence indicating that Deridder in reality resided at 129th Avenue. Both Officers Abascal and Masferrer observed Deridder leave the 129th Avenue residence and enter a red Chevy pickup truck on June 27, 1997. In addition, both officers unequivocally testified that when they interviewed Deridder on that day he indicated that he resided at 129th Avenue but that the address on his license, 132nd Place, was his parents’ address.
See supra
n. 1. It is not unusual for persons of Deridder’s age — the Autotrac report and driver’s license records indicate he was twenty-seven at the time of the entry — to use their parents’ address for records, such as driver’s licenses, official mailing address, et cetera, because in a sense it may be a more permanent or fixed address than the address of their own residence. For example, oftentimes university students or law clerks in their twenties use their parents’ address while studying or clerking. The officers and the courts are entitled to consider such a common sense factor.
See Magluta,
However, this conclusion does not end the first inquiry required by Payton. The *1264 officers must have had a reasonable belief that 129th Avenue was Deridder’s residence at the time of entry — the morning of March 10, 1998. The question becomes, then, whether or not the passage of time and the acquisition of additional information so eroded the reasonable belief that 129th Avenue was Deridder’s residence on June 27, 1997, that believing this was his residence on March 10, 1998, was not reasonable. In other words, unless the belief that Deridder resided at 129th Avenue was still a reasonable belief on March 10, 1998, the entry was unconstitutional.
Agent Mahoney testified that on August 20, 1997, he observed at the 129th Avenue address the red Chevy pickup truck, in which Deridder received a ticket on June 4. 1997, and in which Abascal and Masferrer observed Deridder leave the 129th Avenue address on June 27,1997. The magistrate judge did not mention this fact in. its report and recommendation, nor did the district court note it. 5 Nonetheless, we find this fact important. It extends the basis for believing that Deridder was dwelling at the 129th Avenue residence to August 20, 1997, by showing that the vehicle Deridder was known to drive was there on that date. 6
Furthermore, the August 20, 1997, Au-totrac report on Flight Equipment, Inc., listed Deridder as an historical principle, in particular a former registered agent and director, with an address of 129th Avenue. This report also indicated that the previous address of Flight Equipment, Inc., was 129th Avenue. *' Although the report provided a new address for the company — 832 East 21st Street, the address also given for its current registered agent, Jaime Oubuna, this does not suggest that Derid-der’s address was no longer 129th Avenue. In fact, it suggests just the contrary — ie., while Deridder was the registered agent, the company’s address was Deridder’s address, 129th Avenue, but that when Derid-der became an “Historical” principle the company’s address changed to that of its current registered agent, Oubuna.
In light of the August 20th observation of the Deridder vehicle at the address, we conclude that the officers reasonably believed that Deridder resided at 129th Avenue on August 20, 1997. However, the question remains whether this information and Deridder’s statements to the officers became stale in the 6 months and 21 days between August 20, 1997, and the March 10,1998, entry.
We have developed a staleness doctrine in the context of probable cause which requires that the information supporting the government’s application for a warrant must show that probable cause exists at the time the warrant issues.
See United States v. Harris,
The courts are not without guidance, however. In addition to the length of time, courts should consider the “nature of the suspected crime (discrete crimes or ongoing conspiracy), habits of the accused, character of the items sought, and nature and function of the premises to be searched.”
Harris,
“The circuits hold that where an affidavit recites a mere isolated violation then it is not unreasonable to believe that probable cause quickly dwindles with the passage of time. On the other hand, if an affidavit recites activity indicating protracted or continuous conduct, time is of less significance.”
Bascaro,
Residency in a house, like protracted and continuous criminal activity or projectiles embedded in the house’s walls and floors, generally is not transitory or ephemeral, but instead endures for some length of time. Although Deridder’s statement in June of 1997 and the observations of Deridder in June of 1997 and of his vehicle in June and August of 1997 are isolated pieces of evidence, they support, as we concluded above, a reasonable belief that Deridder resided at 129th Avenue. It was reasonable for the officers to believe that, because Deridder resided at 129th Avenue, he would reside there for some period of time. How long the officers could reasonably believe this period would extend is difficult to say. As in the proba
*1266
ble cause context, we hesitate to set an arbitrary length of time. However, on the facts of this case, we believe that it was reasonable for the officers to believe that the residency extended for at least 6 months and 21 days. As explained below, the officers’ efforts in this case to refresh the information did not indicate that Der-idder had changed residence. In the probable cause context, we have found that information can remain fresh for longer than the period of time at issue here. For example, in
United States v. Hooshmand,
We turn then to the information acquired during this passage of time to determine if it eroded the reasonable belief. On February 4, 1998, Agent Mahoney conducted another Autotrac search on Derid-der. Although this Autotrac report linked Deridder to both the 129th Avenue address and the 132nd Place address, the repórt indicated that its information was as of June, 1997. As of that time, the officers knew that Deridder was living at the 129th Avenue address, and that the 132nd Place address was merely his parents’ address. We readily conclude that the mention here, and elsewhere, of the 132nd Place address does little to undermine the officers’ reasonable belief that Deridder actually resided at the 129th Avenue address, and that he merely used his parents’ address for various documents, such as his driver’s license. 8
Because unobserved, extended surveillance of 129th Avenue was impractical given the neighborhood’s layout, the officers conducted occasional drive-bys of the 129th Avenue residence. On none of these drive-bys after Mahoney’s August 20, 1997, observation did the officers observe either Deridder or the red Chevy truck that Deridder was known to use. The officers, however, did notice a for sale sign. The district court found that the for sale sign was not present on the day of the entry. Bervaldi argues that this should have put the officers on notice that Derid-der no longer resided at 129th Avenue. The court, however, did not find that the officers noticed that the sign was not present. Given that the officers approached the house in predawn darkness,
9
it is understandable that they did not notice its absence. Determinations of reasonable belief are based on “the facts and circumstances within the knowledge of the law enforcement agents.”
Magluta,
Bervaldi argues that the officers could have discovered that Deridder was not residing at 129th Avenue if they had gone beyond the occasional drive-bys and Autot- *1267 rac reports after the summer of 1997. First, Bervaldi argues that a “Dossier” search, another more expansive type of search on the Autotrac system, would have shown that Bervaldi registered a vehicle to the 129th Avenue address in January of 1998. Agent Mahoney indicated that he did not run this type of search because in his experience it was not generally useful. Second, Bervaldi argues that the officers should have at least checked the county property records and that if they had done so they would have discovered that Marcella and Phillip Deridder had sold the house in February. We note that the transfer was not recorded until March 5, 1998, five days before the challenged entry. In light of the other information supporting the officers’ reasonable belief that this was Derrider’s residence, we do not believe that the Constitution required that they also check property records. Likewise, though a check of the utility records prior to the entry would have revealed that the customer was changed from either Marcella Deridder or Phillip Deridder to Beatriz Ramos around the beginning of the year, we do not believe that the officers, in light of the information they already had, were constitutionally obligated to check these records. At oral argument, conceding as much, defense counsel agreed that the law does not currently impose a requirement to check utility records or property records. Although the officers could have checked into these matters, we do not believe that their failure to do so is inconsistent with a reasonable belief that Deridder resided at 129th Avenue. We conclude that the officers had a reasonable belief that 129th Avenue was Deridder’s dwelling on March 10,1998.
Having concluded that the officers reasonably believed that 129th Avenue was Deridder’s dwelling, we turn to the second part of the inquiry: did the officers have “reason to believe” that Deridder was within the dwelling when they entered on the morning of March 10, 1998. The officers approached the house around 6:00 in the morning. They noticed several vehicles parked at the residence. When they knocked on the front door, someone answered the door. We have noted that “officers may presume that a person is at home at certain times of the day — a presumption which can be rebutted by contrary evidence regarding the suspect’s known schedule.”

Because the entry was permitted under

we see no reason Bervaldi’s statements or the evidence seized should have been suppressed. In

III. CONCLUSION
Accordingly, we reverse the district court’s grant of Bervaldi’s motions to suppress and remand for further proceedings.
REVERSED AND REMANDED.
Notes
. Abascal had seen Deridder the previous June, when he and another officer had a brief conversation with him at a food stop. See infra.
. To make the distinction clear, on redirect examination of Abascal, the Government elic- *1260 iled the following:
Q. Did he give you the address for his parents' house before or after you asked to see his driver’s license?
A. He confirmed that his parents lived at the address that was on the face of his driver's license, and that he lived at 3621 129th Avenue address.
Q. Now, in your mind was he making a distinction between what was on his driver’s license and where he was telling you he lived?
A. Absolutely.
Q. And in your mind, where was he telling you that he lived, referring to Bennett Der-idder?
A. 3621 Southwest 129th Avenue.
On direct examination of Masferrer concerning the June 27th interview with Deridder, the Government elicited the following:
Q. What kind of identification did you get from Deridder?
A. I got his driver’s license, and I asked him where he lives. He gave me the address. That address 129th and the address of his father and mother 132nd Avenue.
Q. Which address is shown on his driver license?
A. The one on 132nd Avenue.
Q. You said he gave you the address, 129th Avenue address, what did he say about that address?
A. That he lived there. That was his house. He lived there and his license, the address on his license was his mom’s, his parent’s house.
Q. Did he give you anymore [sic] information at that time about where he was living?
A. He was living on 129th Avenue.
Mahoney also testified that Deridder gave two addresses during the June 27th stop: the 132nd Place address and the 129th Avenue address. He did not explain if or how Derid-der distinguished between them. However, he was not present at the stop. Only Abascal and Masferrer provided first-hand testimony about what Deridder told them about these addresses. As explained above, both unequivocally indicated that Deridder stated that he resided at the 129th Avenue address but that his parents resided at the 132nd Place address, which was on his license. The magistrate judge’s report and recommendation indicates that Deridder told the officers that he lived at both addresses. The report and recommendation, however, does not distinguish between them as the officers did when they testified. To the extent the district court, by adopting this report and recommendation, failed to thus distinguish between these addresses, we find clear error. This error may explain the magistrate judge's apparent overemphasis on the 132nd Place address.
. Ramos is Bervaldi's long-time live-in girlfriend.
. We note that though the parties stipulated that Deridder did not actually reside at 129th Avenue on March 10, 1998, it ultimately became clear that he did not actually reside at 132nd Place either. In fact, Bervaldi led the officers to a Calusa Club Drive residence on March 10, 1998, where officers spoke with .'Deridder’s girlfriend, who stated that he lived there with her.
. There is no indication that the magistrate judge found Mahoney or any of the officers’ testimony noncredible; to the contrary, at the conclusion of the hearing, the magistrate judge remarked, “I think the officers did a very nice job in being very candid,” and in.his report and recommendation, he noted conflicts in the evidence were not resolved on the basis of the credibility of witnesses.
. Bervaldi argues that the district court, by stating "No information obtained after June 1997 ever established or confirmed that Der-idder was still living at the 129th Avenue location, even part-time, or as one of two residences on March 10, 1998,” and "No vehicles owned or operated by DeRidder were traceable to that location between June 1997 and March 1998,” made an implicit finding that the August 20, 1997, observation, which the district court failed to mention, was not evidence linking Deridder to that location. To the extent the district court made a factual finding that no evidence linked Deridder to the 129th Avenue residence after June 27, 1997, we find it clearly erroneous in light of the August 20, 1997, observation of the Derid-der vehicle at that address.
. Decisions of the former Fifth Circuit rendered prior to October 1, 1981, are circuit precedent in the Eleventh Circuit.
See Bonner v. City of Prichard,
. The district court found that the Autotrac report "showed no current information at all on addresses linked to Deridder after June, 1997.” We agree. Despite the agent's efforts to refresh the information acquired in June, the Autotrac report revealed nothing more recent about Deridder’s residence.
. According to the charts calculated by the United States Naval Observatory, the sun rose in Miami on March 10, 1998, at 6:35 a.m. See Astronomical Applications Department, U.S. Naval Observatory, Sun or Moon Rise/Set Table for One Year, (accessed Aug. 7, 2000) <http://aa.usno.navy.mil/AA/data/docs /RS ONEYEAR.html>. We take judicial notice of this fact. See Fed.R.Evid. 201.
.In any event, the absence of the sign permits several possible inferences including that the owners abandoned their attempts to sell the house and that they sold the house but that Deridder still resided there as a tenant, as well as that the house was sold causing Deridder to move.
. We note that Bervaldi's reliance on
Steagald v. United States,
.Bervaldi does not argue that the mode of entry was unreasonable under the circumstances. Although the officers kicked the door down and entered, Bervaldi's failure to' rely on this is understandable in light of the following facts: the officers had knocked on the door for ten minutes; a man whom the officer thought was Deridder finally answered the door and seemed to be concealing something, which the officers thought was a gun behind his back; and when the officers, with jackets featuring the word "police,” announced themselves as police, the man promptly slammed the door in their faces. In light of the foregoing facts and the finding of the court below that the officers believed it was Deridder, it is understandable that Ber-valdi argues on appeal only the two prongs of the Magluta inquiry — whether there was a reasonable belief that it was Deridder’s residence, and whether there was a reasonable belief that Deridder was there at the time— and it is understandable that Bervaldi's primary focus is on the former prong.
. We note that ordinarily a firearm found on an arrestee does not imply the possible presence of another armed individual.
See United States v. Chaves,
. In his brief on appeal, Bervaldi claims that "the agents opened closets, kitchen cabinets and bedroom drawers.” There is no support in the record for this claim. Rather, the testimony of Officers Abascal and Masferrer indicates that the search was properly limited in scope. We also note that during a protective sweep, officers are permitted to open closets, assuming they could harbor a person.
