OPINION OF THE COURT
Nicole Gardner (“Appellant”) appeals the order of the United States District Court for the Western District of Pennsylvania granting summary judgment in favor of State Farm Fire and Casualty Company (“State Farm”), and denying summary judgment in Appellant’s favor. At issue is the District Court’s disposition of Appellant’s claims arising out of State Farm’s refusal to defend or indemnify its insured, Kevin Harper, in connection with negligence claims Appellant asserted against Harper in a state court action. We have jurisdiction pursuant to 28 U.S.C. § 1291. We affirm.
I.
Kevin Harper purchased a residence on Sole Street in McKeesport, Pennsylvania (the “Property”) sometime in the 1980’s. Harper lived at the Property until March 1, 2002, when he moved in with his girlfriend on Scott Street, around the corner from the Property. To maintain the mortgage on the Property, he rented it to Appellant pursuant to a March 1, 2002 written lease agreement. Although the initial term of the lease agreement was six months, Appellant continued to rent the Property until February 1, 2003, when Harper evicted her on account of her failure to keep current on the rent. Meanwhile, on August 29, 2002, Appellant’s mother, Sharon Ann Gardner (“Appellant’s Mother”), slipped and fell on the sidewalk outside the Property and was injured.
Harper had a Homeowner’s Insurance Policy with State Farm (the “Policy”). On March 7, 2003, Appellant advised State Farm of her Mother’s fall and resulting injuries. As a result, State Farm conducted an investigation, which included obtaining the statements of Appellant and Harper. Pursuant to that investigation, State Farm learned for the first time that Harper was renting out the Property. On April 4, 2003, State Farm sent a letter to Harper, denying coverage and explaining that the Policy “does not offer coverage for bodily injury when the property is held for *557 rental and is no longer occupied by the insured.” App. at A189.
On March 31, 2004, Appellant’s Mother passed away. On August 25, 2004, Appellant filed a negligence action against Harper on behalf of her Mother’s estate in the Court of Common Pleas of Alegheny County (the “State Court Action”). In a September 10, 2004 letter to Harper, State Farm reiterated that because Harper “held the residence premises for rental and did not occupy any part of it when this accident occurred,” it was denying coverage and would not provide him with a defense to Appellant’s claims. App. at A195. Appellant obtained an entry of default against Harper in the State Court Action on May 18, 2006, and the court entered judgment against Harper in the amount of $1,664,757.52, plus costs and interest, on June 16, 2006.
On April 8, 2005, Appellant’s counsel filed a Praecipe for Writ of Summons in the Court of Common Pleas of Alegheny County, and captioned the case Kevin Harper v. State Farm Fire & Cas. Co., even though Appellant had not received an assignment of Harper’s rights against State Farm and Harper had not authorized Appellant’s counsel to act on his behalf. Subsequently, on June 22, 2005, Harper assigned his rights against State Farm to Appellant (the “Assignment”), and Appellant executed the Assignment on June 29, 2005. That same day, Appellant served the Praecipe for Writ of Summons on State Farm. Exactly one month later, on July 29, 2005, State Farm removed the action to federal court. On September 14, 2005, Appellant’s counsel filed a Complaint against State Farm, again in Harper’s name, and on December 6, 2005, counsel filed a motion pursuant to Federal Rule of Civil Procedure 17 to substitute Appellant, as administratrix of her Mother’s estate, as the real party in interest. The District Court granted that motion on December 13, 2005.
Appellant’s Complaint in this case asserts six claims: breach of contract, breach of fiduciary duty, negligence, statutory bad faith pursuant to 42 P.S. § 8371, violation of Pennsylvania’s Unfair Trade Practices and Consumer Protection Law (the “UTPCPL”), 73 P.S. § 201-1 et seq., and a claim for punitive damages. Appellant’s essential complaint is that State Farm breached its contractual and statutory duties to Harper by refusing to defend Appellant’s suit against him, failing to indemnify him for the judgment against him, and failing to evaluate the case in good faith. At the completion of discovery, both parties filed motions for summary judgment. The District Court granted State Farm’s motion, denied Appellant’s cross-motion, and entered judgment in State Farm’s favor.
II.
Appellant asks us to find that the District Court erred in granting summary judgment in State Farm’s favor and denying judgment in her favor.

Our standard of review of a grant of summary judgment is plenary.

III.
Appellant first argues that the District Court erred in finding that the Policy-afforded Harper no coverage for her claims against him and therefore erred in entering judgment in State Farm’s favor on her breach of contract and breach of fiduciary duty claims. This argument is meritless.
In denying coverage for Appellant’s claims, the District Court relied on the following exclusion in the Policy, i.e., the “Rental Exclusion.”
Section II — Exclusions
1. Coverage L [Liability] and Coverage M [Medical] do not apply to:
b. bodily injury or property damage arising out of the business pursuits of any insured or the holding for rental of any part of the premises by any insured. This exclusion does not apply:
(3) to the rental or holding for rental of a residence of yours:
(a) on an occasional basis for the exclusive use as a residence;
App. at A 140.
Appellant argued to the District Court, and continues to argue, that the Rental Exclusion is inapplicable because Harper’s rental of the Property was on “an occasional basis” and was therefore subject to the exception set forth in subparagraph (3)(a), the “Occasional Basis Exception.” In the alternative, Appellant argues that the Occasional Basis Exception is ambiguous and should therefore should be construed in Harper’s favor.
Under Pennsylvania law, which the parties agree is applicable here, the “interpretation of an insurance contract regarding the existence or non-existence of coverage is generally performed by the court.”
Donegal Mut. Ins. Co. v. Baumhammers,
In rejecting Appellant’s argument that the Occasional Basis Exception was either ambiguous or plainly applicable under the circumstances of this case, the District Court considered the definition of “occasional” in the 2003 edition of the Merriam-Webster Dictionary, which is, in relevant part: (1) “of or relating to a particular occasion,” or (2) “encountered, occurring, appearing, or taken at irregular or infrequent intervals.” App. at A17 (quoting Merriam-Webster’s Collegiate Dictionary (Merriam-Webster, 11th Ed.2003)). The court held that under either of these definitions, coverage was not available for Appellant’s claims as Appellant’s rental was neither on a particular occasion nor taken at irregular or infrequent intervals. In this regard, the trial court emphasized that *559 Appellant “rented the property continuously for almost one (1) year which is, practically speaking, the entire term of the annually renewable policy.” App. at A18. It further stated that requiring coverage under those circumstances would not be reasonable as it would distort the meaning of the Policy language and would “effectively transform a homeowner’s insurance policy into a landlord’s insurance policy and render the applicable exclusions meaningless.” App. at A18.
We agree with the District Court that, under the circumstances of this case, the Rental Exclusion unambiguously excludes coverage and the Occasional Basis Exception is unambiguously inapplicable. Appellant attempts to inject ambiguity into the Occasional Basis Exception by arguing that the rental was on the single “occasion” of Harper’s attempting to get caught up on his mortgage, and that it was likewise “infrequent” and “irregular” because it occurred for just an 11-month period over more than 15 years of ownership. However, these arguments rely on unreasonable interpretations of the Occasional Basis Exception. First, a homeowner’s rental of his property in order to finance his mortgage is nothing more than a business pursuit, which is exactly what triggers the application of the Rental Exclusion in the first place and, thus, cannot also be the “occasion” that triggers the Occasional Basis Exception. Second, we reject the assertion that the relevant time period for assessing the infrequency or irregularity of the rental is the length of Harper’s ownership rather than the term of the insurance policy, because the Policy addresses only the rental term and plainly anticipates that the norm during that term will be the insured residing at the property, not renting it out.
See, e.g., State Farm Fire & Cas. Co. v. Piazza,
We also find that the District Court did not err in finding no coverage for Appellant’s claims in the State Court Action, because a second exclusion in the Policy, the “Insured Location Exclusion,” also precluded coverage. That exclusion provides as follows:
Section II — Exclusions
1. Coverage L [Liability] and Coverage M [Medical] do not apply to:
d. bodily injury or property damage arising out of any premises currently owned or rented to any insured which is not an insured location....
App. at A140. The Policy defines “insured location,” in relevant part, as “the residence premises,” and “any part of any other premises ... used by you as a residence.” App. at A126. “Residence premises” is defined as the premises “where you reside and which is shown in the Declarations.” Id.
Harper simply was not residing at the Property at the time that Appellant’s Mother was injured. Under Pennsylvania law, an individual’s residence for purposes of an insurance policy is his “factual place of abode,” which is “a matter of physical fact.”
Amica Mut. Ins. Co. v. Donegal Mut. Ins. Co.,
Appellant argues, in the alternative, that even if State Farm had no duty to
indemnify
Harper under the Policy, it should have at least
defended
him in the State Court Action as the duty to defend is determined by the scope of the allegations in the Complaint and, here, the Complaint specifically alleged that the Property was Harper’s residence and that he rented it to Appellant on an occasional basis for the exclusive use as a residence.
See Frog, Switch & Mfg. Co. v. Travelers Ins. Co.,
IV.
Appellant next argues that the District Court erred in entering judgment in State Farm’s favor on her negligence and statutory bad faith claims on statute of limitations grounds. The statute of limitations for both negligence claims and statutory bad faith claims pursuant to 42 Pa. Cons.Stat. Ann. § 8371 are two years. 42 Pa. Cons.Stat. Ann. § 5524;
Ash v. Cont’l Ins. Co.,
Appellant takes issue with the District Court’s critical conclusion that the action was not “commenced” for statute of limitations purposes until the execution of the Assignment. She specifically argues that Federal Rule of Civil Procedure 15(c)(1) provides that an amendment that changes the party or the naming of the party relates back to the date of the original pleading, so long as the claim asserted arose out of the same conduct, transaction or occurrence set forth in the original pleading, as it did here.
In our view, however, Rule 15(c)(1) is simply not applicable here, as, by its own terms, it applies only to amendments to the “party ... against whom a claim is asserted>” that is, the defendant. Fed.R.Civ.P. 15(c)(1)(C) (emphasis added). Indeed, the Advisory Committee Notes to Rule 15 explicitly state that the “relation back of amendments changing plaintiffs is not expressly treated in revised rule 15(c) ...” and that “the attitude taken in ... Rule 15(c) toward change of defendants extends [only] by analogy to amendments *562 changing plaintiffs.” Advisory Committee Notes on the 1966 Amendments to the Fed.R.Civ.P. 15. The more applicable Rule is Federal Rule of Civil Procedure 17, which provides that “[a]n action must be prosecuted in the name of the real party in interest” and that a court may dismiss an action for failure to prosecute in the name of the real party in interest after affording the real party in interest a reasonable time to ratify, join or be substituted in the action. Fed.R.Civ.P. 17(a)(1), (3). That protection against dismissal “is designed to avoid forfeiture and injustice when an understandable mistake has been made in selecting the party in whose name the action should be brought.” 6A Charles Alan Wright, Arthur R. Miller, & Mary Kay Kane, Federal Practice & Procedure, § 1555 (2d ed.2008). Thus, it “should be applied only to cases in which substitution of the real party in interest is necessary to avoid injustice.” Id.
Here, Appellant named the “real party in interest” in commencing suit, by filing it in Harper’s name. Fatally, however, she had no authorization to do so.
3
Thus, in actuality, it was she who commenced the suit, not Harper, and she was not yet a real party in interest, because Harper had not yet assigned his rights to her.
See FDIC v. Deglau,
Notably, the United States Court of Appeals for the Ninth Circuit addressed a situation similar to ours in
United States ex rel. Wulff v. CMA, Inc.,
... [T]he requirement that a person suing under the Miller Act must have furnished labor or material to the federal construction project is a condition precedent to the existence of the cause of action. This element was lacking when [plaintiffs] filed their original complaint. Therefore, they did not have a Miller Act claim on which they could sue at that time. When they later obtained the assignment from [the subcontractor] the statute of limitations had run. Thus, ... the supplemental pleading in which the [plaintiffs] alleged that they had obtained the assignment from [the subcontractor] will not relate back to create a Miller Act claim which the [plaintiffs] did not have when they filed their original complaint.
Rule 17(a) does not apply to a situation where a party with no cause of action files a lawsuit to toll the statute of limitations and later obtains a cause of action through assignment. Rule 17(a) is the codification of the salutary principle that an action should not be forfeited because of an honest mistake; it is not a provision to be distorted by parties to circumvent the limitations period. [The subcontractor’s] assignment to the [plaintiffs] of its claim against CMA cannot ratify the [plaintiffs’] commencement of suit on a claim which theretofore did not exist.
Id. at 1075.
Applying this same rationale to the instant case, we conclude that Harper’s assignment of his claims against State Farm to Appellant after the statute of limitations had run was legally ineffective to save the claims from the statute of limitations bar.' 4 Thus, we affirm the District Court’s dismissal of the negligence and statutory bad faith claims on statute of limitations grounds. 5
*564 V.
Appellant also argues that the District Court erred in failing to separately analyze her claims that State Farm breached the insurance contract and its fiduciary duties by conducting an inadequate claims investigation, concluding “very early” that the Rental Exclusion applied, without conducting a “complete and objective investigation” that would have uncovered relevant facts and “ignoring] the answers that it did receive.” According to Appellant, these claims are not contingent on the underlying success of her claims that State Farm beached the insurance contract by failing to provide coverage as they hinge entirely on State Farm’s alleged investigatory misconduct.
Even if we were to accept Appellant’s premise that her claims based on State Farm’s alleged investigatory misconduct can survive our determination that State Farm had no duty to defend or indemnify Harper against Appellant’s claims, we conclude that the undisputed record evidence establishes that State Farm breached no duties to Appellant in connection with its investigation. According to Appellant, State Farm should have asked a whole host of questions to more accurately determine Harper’s residency, should have obtained Harper’s statement under oath, and should have obtained an outside legal opinion regarding the applicability of the Occasional Basis Exception. However, as explained above, State Farm properly denied coverage based on its correct conclusion that the Occasional Basis Exception did not apply, and Appellant cites to no facts that State Farm would have obtained in a more thorough investigation that would have established otherwise. Accordingly, the District Court did not err in granting judgment in State Farms’s favor, even insofar as Appellant asserted claims based on State Farm’s allegedly inadequate investigation.
VI.
Finally, Appellant argues that the trial court erred in granting summary judgment in State Farm’s favor on Appellant’s UTPCPL claim. As the District Court explained, the UTPCPL is designed to protect the public from fraud and deceptive business practices.
Pirozzi v. Penske Olds-Cadillac-GMC, Inc.,
Here, as the District Court stated, “the undisputed evidence establishes that [State Farm] committed neither malfeasance nor did it improperly perform a contractual *565 obligation.” App. at A24. The District Court was entirely correct in that regard; there is no basis in the record or the law for a conclusion that State Farm engaged in malfeasance. We therefore affirm the District Court’s decision in that regard as well.
IV.
We have considered all other arguments made by the parties on appeal, and conclude that no further discussion is necessary. For the foregoing reasons, we will affirm the District Court’s order granting summary judgment in favor of State Farm and denying summary judgment to Appellant.
Notes
. Although an order denying motion for summary judgment is not ordinarily final and appealable, it becomes appealable when accompanied by an order granting a cross-motion for summary judgment.
Nazay v. Miller,
. Our conclusion in this regard is consistent with other court decisions that have considered the Occasional Basis Exception.
See State Farm Fire & Cas. Co. v. Wonnell,
. Harper’s testimony at his deposition on June 12, 2006 was as follows:
Q: Nows, did [Appellant’s two attorneys] ever act as your lawyer?
A: No. First time I met them.
Q: So you never met either one of them before today?
A: No.
Q: Is that correct?
A: Never.
Q: And they have represented to me that neither one of them has ever talked to you about either the coverage case or the underlying case — well, strike that — about the question of your coverage with State Farm or any issue about that. Is that right?
A: What do you mean?
Q: That you never talked to them about State Farm or your policy. Let me ask it this way. Do you recall any conversation you ever had with either one of them?
A: On the phone.
Q: Okay. What do you recall about that conversation, and who was it with?
A: Well, just who my insurance was.
Q: Okay.
A: My insurance carrier.
Q: They wanted to find out the name of your insurance carrier?
A: That was it.
Q: And that was the extent of the conversation?
A: That was it. That was the only thing.
App. at A271-A272.
. State Farm has argued that Appellant’s action against it was void ab initio because Appellant commenced the State Court Action in Harper’s name without the authority to do so. However, having found no clear authority for such a drastic remedy, we decline to impose it here. We nevertheless observe that we were very surprised to learn that Appellant’s counsel filed the State Court Action in Harper’s name without Harper’s consent and misrepresented in that filing that they were Harper’s counsel. We strongly caution attorneys against engaging in similar conduct in the future.
. We also reject Appellant's arguments that (1) the April 2003 letter was not a clear and unambiguous denial of coverage, and (2) that there was no proof that the denial letter was actually mailed and received. Specifically, we find that the plain language of the letter was a clear and unambiguous denial, App. at A190 ("Since you held the residence premises for rental and did not occupy any part of it *564 when this accident occurred, we must deny coverage for this claim.”), and the record is clear that the letter was sent and Harper does not deny receiving it. See App. at A41, A71-A72. While we do not know the exact date on which Harper received the letter, the few days of uncertainly are inconsequential given that Harper did not assign his claims to Appellant until more than two months after the statute of limitations had expired, making the precise date on which the statute began to run immaterial to our analysis.
