This controversy raises important questions for the interpretation of contracts when a party alleges that a contract is ambiguous and seeks to admit extrinsic evidence to show the intent of the contracting parties. Factually, the case involves the interpretation of a release provision of a mortgage contract covering about six acres of land in Howard County. The trial court found the provision ambiguous and used extrinsic evidence to determine the amount that the Respondent must pay to obtain a release from the mortgage. Applying a de novo standard of review, we conclude that, viewed objectively, the release provision is unambiguous. We therefore reverse, holding that the trial court erroneously admitted extrinsic evidence and interpreted the contract in contradiction to its express terms.
I.
The dispute arises out of the 1992 purchase for $1.2 million of 38 acres of undeveloped land in Howard County. New *429 Panorama Development Corporation (New Panorama) purchased the property from Robert F. Simpson, who secured $654,000 of the purchase price with a mortgage. The mortgage covered Lot 126, which contained a little more than six acres, and was dated December 31, 1992. In 1995, New Panorama subdivided Lot 126 into two lots, creating Lot 130, about which this dispute centers. New Panorama enlarged Lot 130 by 2,200 square feet from adjacent land unencumbered by the Simpson mortgage. Lot 130 was transferred in August, 1995, to Lovell Regency Homes (Lovell). After constructing a single family residence on the property, Lovell sold the property to Respondent Caryn Woods (Woods) on February 23,1996.
Lovell did not record its deed from New Panorama until February 26,1996, three days after it had sold the property to Woods. The deed to Woods was not recorded until the afternoon of March 13, 1996. By that time, the Simpson mortgage had matured and was in default. The trustees of the Simpson mortgage filed for foreclosure on the mortgage for the full amount, $654,000. 1 A foreclosure sale took place in the morning of March 13, 1996, only a few hours before the Woods deed was recorded. Exceptions to the foreclosure were filed by numerous parties, including New Panorama, Lovell, and Woods. In July 1996, Woods filed a petition for reformation and partial release of the mortgage. Woods’ petition argued that the transfer of Lot 130 to Lovell and then to her without obtaining a partial release was by inadvertence and mistake, and requested the trial court to set a partial release amount, which Woods’ title insurer was willing to pay. The mortgagee filed a motion for summary judgment. The trial court granted the mortgagee’s request for summary judgment as to the claim for reformation, but allowed the petition to set a figure for partial release to proceed.
*430 The ruling on the petition for partial release is what is before us. Woods’ request for a partial release of the mortgage is based on the following provision in the mortgage contract between New Panorama and Simpson:
“Upon request of the Mortgagor, Mortgagee shall release portions of the mortgaged premises as follows:
Subdivided lots shall be released by payment by Mortgagor to Mortgagee of an amount equal to $752,100.00 [ 2 ] divided by the total number of subdivided residential building lots in a recorded subdivision plat of the mortgaged premises, from time to time.
All releases shall be prepared at the expense of Mortgagor and shall be executed by the Mortgagee when requested by Mortgagor.
Mortgagee shall not unreasonably refuse to execute or join in the execution of plats of subdivision, record plats, deeds or other grants of rights of way and easements for the installation and maintenance of sanitary rights of way and easements for the installation and maintenance of sanitary sewers, storm drainage, water, electricity and other utilities for the benefit of the mortgaged premises; provided such execution or joinder does not subject the Mortgagee to any cost, liabilities or expenses in connection therewith.” (Emphasis added).
While most of the mortgage contract consists of a standard form, with the specifics of the transaction typed into blank spaces, the entire release provision quoted above appears not to be a part of the standard form, but rather inserted by the contracting parties, as evidenced by the different and slightly larger typeface of the release provision. 3
*431 The emphasized text from the excerpt quoted above, which describes how the partial release figure will be computed, is the contractual language that has been the main point of contention in this dispute. The trial court “specifically [found] that the release provision is sufficiently ambiguous that extrinsic evidence needs to be considered in determining the intention of the parties at the time the mortgage was executed.” The court gave no explanation of its finding of ambiguity in its written order other than the statement just quoted. The trial court then considered evidence of negotiations taking place prior to the execution of the mortgage, admitting into evidence exhibits and testimony from four witnesses. Based on this evidence, the court concluded that “the parties never intended to create a situation where one lot ... would bear the entire burden of the mortgage.” Referring to a letter written by an attorney representing the mortgagee on May 4, 1992, more than six months prior to the signing of the mortgage, the trial court found that “[e]vidence adduced at trial established the fact that pro rata release prices had been discussed by the parties.” The trial court then concluded that a pro rata release, ie., basing the partial release on the acreage of encumbered land in the Woods lot relative to the total land subject to the mortgage, was the “fair and equitable result.” It rejected as leading to “an unfair and unreasonable result” the interpretation proposed by the mortgagee, that the denominator by which to divide the total amount of the mortgage was one, since the Woods lot was the only platted and recorded residential building lot on the mortgaged property. The court therefore arrived at a partial release figure of $21,058.80 by computing the percentage of encumbered land in Woods’ lot (7,416 square feet) relative to the total land encumbered by the mortgage (267,101.21 square feet) and multiplying that percentage (2.8%) by the total release amount of $752,100.00.
In an unreported opinion, the Court of Special Appeals applied a clearly erroneous standard to affirm the trial court’s finding of ambiguity. Under that standard, the court said it would had to have found “no reasonable suggestion of ambigú *432 ity” in the contractual language in order to reverse the trial judge’s finding of ambiguity. The intermediate appellate court pointed to the specific contract language “from time to time” as ambiguous. Judge Kenney dissented on the grounds that the release provision was clear in setting the release based on the total number of subdivided residential building lots then platted and recorded and that the trial court’s method of determining the release price was not reflected in the language of the mortgage contract nor in the negotiations.
We granted certiorari in order to address the issues of contract interpretation raised in this case.
Calomiris v. Woods,
II.
As just described, the trial court in this case declared the partial release provision ambiguous and then sought to ascertain the intent of the parties through the use of evidence extrinsic to the contract itself. These actions implicate the role of the judiciary in contract interpretation and the use of extrinsic evidence for interpretative purposes. Maryland law generally requires giving legal effect to the clear terms of a contract and bars the admission of prior or contemporaneous agreements or negotiations to vary or contradict a written contractual term.
Equitable Trust Co. v. Imbesi,
“after concluding their negotiations, want to simplify the administration of the resulting contract and to facilitate the resolution of possible disputes by excluding from the scope of their agreement those matters that were raised and dropped or even agreed upon and superseded during the negotiations. It is often useful to be able to replace the negotiations of yesterday with an authoritative agreement of today.”
E. Allan Farnsworth, II Farnsworth on Contracts § 7.2, at 214-15 (1998).
As with many legal rules, however, there are situations that render the rule inoperable. All courts generally agree that parol evidence is admissible when the written words are sufficiently ambiguous. E. Allan Farnsworth, II Farnsworth on Contracts § 7.11, at 292 (1998). The remainder of this part of the opinion (1) explains the appropriate standard by which the appellate courts should address a trial court’s ruling on a party’s claim of contract ambiguity, (2) considers the appropriate substantive test for determining whether contractual language is ambiguous, and (3) reviews some of our prior decisions on the ambiguity exception to the rule against admitting extrinsic evidence for contract interpretation. Part III of the opinion then applies this law to the dispute raised in the instant case.
A.
Initially, we address the appropriate standard of review for interpreting the terms of the mortgage. As noted above, the Court of Special Appeals applied a clearly erroneous standard to uphold the trial court’s finding of ambiguity, relying as authority for its application of this standard on
Admiral
*434
Builders v. South River Landing,
The rules of contract interpretation apply to our review of the language of a mortgage.
Leisure Campground v. Leisure Estates,
Thus, the determination of ambiguity is one of law, not fact, and that determination is subject to
de novo
review by the appellate court. As in the case of a review of an order of summary judgment,
de novo
review is appropriate because the appellate court’s determination of whether written contractual language is ambiguous turns on whether the trial court was legally correct.
See Heat & Power v. Air Products,
The standard of review afforded the trial court’s ruling on ambiguity differs from the standard applied to a trial court’s factual findings based on parol evidence after the court has determined that the contract language is ambiguous. Should the appellate court agree with the trial court’s finding of ambiguity, it will apply a clearly erroneous standard to the trial court’s assessment of the construction of the contract in light of the parol evidence received. In sum, on appeal, de novo review applies to the initial determination of whether contractual language is ambiguous, and the clearly erroneous standard comes into play only after the trial court’s finding of ambiguity is upheld. Therefore, the Court of Special Appeals erred in this case by deferring under the clearly erroneous standard to the trial court’s finding that the contract language was ambiguous.

In determining whether a writing is ambiguous, Maryland has long adhered to the law of the objective interpretation of contracts.
State v. Attman/Glazer,
*435 "(e) Entry of judgment. The court shall enter judgment in favor of or against the moving party if the motion and response show that there is no genuine dispute as to any material fact and that the party in whose favor judgment is entered is entitled to judgment as a matter of law.”
*436 Therefore, when interpreting a contract the court’s task is to:
“[Djetermine from the language of the agreement itself what a reasonable person in the position of the parties would have meant at the time it was effectuated. In addition, when the language of the contract is plain and unambiguous there is no room for construction, and a court must presume that the parties meant what they expressed. In these circumstances, the true test of what is meant is not what the parties to the contract intended it to mean, but what a reasonable person in the position of the parties would have thought it meant. Consequently, the clear and unambiguous language of an agreement will not give away to what the parties thought that the agreement meant or intended it to mean.”
General Motors Acceptance,

We have frequently barred the admission of extrinsic evidence when the written contractual language is unambiguous. In
Jenkins v. Karlton,
“[t]he only purpose for which the evidence ... was offered was to prove the parties’ intention concerning when the promissory note was payable. On that point, the note is clear and unambiguous, however. By its terms, Jenkins unconditionally agreed to pay the note, according to its terms, on demand. Consequently, parol evidence was not admissible to inject a condition not apparent on the face of the note.”
Jenkins,
In
Creamer v. Helferstay,
“It is true that an unintentional ‘material misrepresentation of fact ... may warrant rescission by a Court of equity of a contract induced thereby.’ However, the trial court overlooked an important principle made clear by the cases regarding rescission for misrepresentation absent fraud or other intentional culpable conduct. That is, in order to be a ground for rescission, the alleged innocent misrepresentation inducing the signing of the contract may not vary or contradict an express term of the written instrument.
* * *
The parol evidence rule precludes the granting of relief for unintentional representations preceding the contract which conflict with the terms of the contract.” (Emphasis added) (citations omitted).

In
Attman/Glazer, supra,
a state agency had a long-term lease for property owned by Attman. Anticipating that the agency may choose to exercise its right to condemn the property during the term of the lease, the parties agreed on a lease provision providing for valuation of the property based on the average of three appraisals of the lessor’s interest in the property. The lessor argued that the valuation provision was ambiguous as to whether the appraisals should ascertain the property’s value as a fee simple absolute or as a fee simple subject to the state agency’s leasehold estate. Turning to basic principles of property law, we held that the contract was unambiguous in requiring that the valuation should be based on the lessor’s interest during the term of the lease.
Attman/Glazer,
III.
A.
In the instant case, parol evidence was admitted solely for the purpose of determining the numeric denominator by which the total release figure of $752,100 was to be divided in order to arrive at the amount that must be paid for a particular encumbered parcel to be released from the mort *440 gage. The express language of the partial release provision calls for the denominator to be determined by “the total number of ... lots.” Other language in this provision establishes what counts as.a “lot.” In arguing for ambiguity, Woods does not assert that the language expressly stating that the denominator will be calculated based on the number of lots is ambiguous; rather, she asserts that the other language is ambiguous in terms of how to properly compute the number of lots that are added together for use as the denominator. 6 Indeed, Woods’ brief to this court quite succinctly concedes that:
“The release provisions, instead of establishing a fixed release price for each lot, establish a formula to set the release fee by division of the amount of $752,100.00 divided by the total number of subdivided residential building lots in a subdivision plat of the mortgaged premises.” (Emphasis added)(footnote omitted).
Thus, Woods does not dispute that the denominator by which the total mortgage is to be divided is a number of “lots.”
Woods’ interpretation, however, does not resolve the ambiguities she alleges. The proposed interpretation takes unambiguous language calling for a denominator based on “the total number of ... lots” and replaces it with a denominator based on acreage, thereby contradicting what she concedes is the express language of the contract. Moreover, she concedes that the written contract does not “establish^ ] a fixed release price for each lot,” but she contradicts this concession by proposing a fixed price for each lot based on its acreage. Finally, while the phrase “from time to time” appears vague superficially, the phrase more plausibly addresses the parties’ belief at the time of contracting that not all the residential plats may be recorded simultaneously, but that they may be recorded as the property is developed, and the partial release fee would change accordingly. Regardless, the record does not reflect any dispute over the timing by which the number of *441 lots should be measured for purposes of determining the release amount; therefore, any ambiguity in the phrase “from time to time” cannot justify avoiding application of the express terms through an analysis of the parties’ intent. As a result, even if we were to agree that the language alleged by Woods was ambiguous, we would have to reverse because there is no nexus between the alleged ambiguities, the contract language necessary to resolve this dispute, and the alternative interpretation of the partial release provision that Woods proposes.
The exception to the parol evidence rule allowing extrinsic evidence to resolve ambiguous contractual language therefore is narrower than Woods contends and than the courts below held in this case. One may not argue ambiguity in one contractual term or clause in order to gain the admittance of extrinsic evidence to contradict other terms or clauses in the contract that are unambiguous. The extrinsic evidence admitted must help interpret the ambiguous language and not be used to contradict other, unambiguous language in the contract.
Cf. State Highway,
Woods’ interpretation also would render unnecessary and superfluous a significant portion of the release language in the contract. Where possible, courts should avoid interpreting contracts so as to nullify their express terms. In
State Highway,
we examined a much more complex contract relating to the construction and material costs of a major highway
*442
contract. The proposed “ambiguous” interpretation would have rendered the contractual language “as directed by the Engineer” redundant and thus superfluous. We rejected that interpretation, stating the general rule that “this Court will ordinarily avoid interpreting contracts in a way that renders its provisions superfluous.”
State Highway,
On the other hand, if, as Woods contends and the trial court found, the contracting parties’ intent was really to divide the mortgage pro rata based on the acreage, we do not believe that any problems of draftsmanship would have prevented those intentions from being explicitly spelled out. Indeed, it seems readily apparent that language calling for the mortgage to be allocated to the property on a pro rata basis (i.e., based on the ratio of the size of the parcel for which a partial release is sought to the size of the total encumbered property) would have been substantially simpler to write than the language that was actually used in the contract, which includes no indication that a pro rata release was intended. Furthermore, as noted in footnote 3, supra, the partial release provision was written especially for this particular mortgage contract and did not make use of boilerplate language like much of the contract. One may safely assume that since the parties took the time to draft the more complicated per lot release rather than drafting a simpler pro rata release, the per lot release is what they probably intended.
*443 B.
Our prior decisions applying the parol evidence rule to exclude the admission of extrinsic evidence, see supra Part II. C, make application of the rule to this case quite clear. The instant case, for example, is not complicated by the need to turn to legal principles external to the contract for interpretative purposes since the question raised here is answered in the contract language. Thus, this case is more easily resolved in favor of excluding extrinsic evidence than Attman/Glazer, supra, where we had to turn to the law of property in order to determine the appropriate property interest referred to in the contract.
Furthermore, the letter showing that the parties discussed establishing the partial release based on square footage was written more than six months prior to the date the mortgage was finally signed. The method of calculating the release could have changed innumerable times over the six months before settlement, and there was testimony that the release provision was subject to extensive negotiations and changed on a daily basis up until the time of settlement. In Jenkins, supra, we held that the evidence should not have been admitted when there were communications between the contracting parties subsequent to entering the agreement that supported Jenkins’ argument that the note was not payable on demand. Because the communications in Jenkins were subsequent to the finalization of the contract, the policy reasons for excluding the evidence by applying the parol evidence rule were considerably weaker than in the instant case. A fortiori in the instant case, where no evidence was presented that subsequent to entering the mortgage contract the parties considered the release provision as being based on a pro rata basis, failure to exclude the extrinsic evidence would completely subvert the policy goal of resolving potential disputes with a contract by allowing evidence of pre-contractual negotiations to vary the terms of a final written contract.
Finally, the fact that this case involves a real property transaction provides even stronger reason for restricting the
*444
use of extrinsic evidence to vary the written contractual terms. In
Pumphrey v. Kehoe,
On appeal, we affirmed the circuit court’s refusal to admit the parol evidence that Kehoe had assumed liability for the $6,600. We stated that:
“A rigid enforcement of the parol evidence rule should occur in cases involving the sale of an interest in land in which the Statute of Frauds ... requires that the contract be evidenced by a writing, signed by the party to be charged, in order to be enforced. [In our opinion t]he alleged oral contract ... would vary, alter or contradict the provisions of the written contract. * * * As we have observed, the written contract ... contains no language which specifically assumes any alleged obligation under the prior contract ... between Mr. Tessitore and the plaintiffs. * * * [The] contract states that ‘the total price ’ (Emphasis supplied.) of the subject property is $8,500.00 which the *445 purchasers agreed to pay in ‘cash at the date of conveyance.’ No other consideration is mentioned. The language is clear and unambiguous.” (Emphasis added; citations omitted).
Pumphrey,
C.
It is a fundamental principle of contract law that it is “improper for the court to rewrite the terms of a contract, or draw a new contract for the parties, when the terms thereof are clear and unambiguous, simply to avoid hardships.”
Canaras v. Lift Truck Services,
The trial court’s ruling in the instant case appears to have overlooked these principles in its desire to arrive at a “fair” result. In adopting the pro rata partial release proposed by Woods, the trial court emphasized that such a *446 construction of the partial release provision constitutes the “only fair and equitable result” and that the “contract construction advocated by [the mortgagee] would result in an unfair and unreasonable result as it would require Ms. Woods to pay a release fee equal to the entire mortgage amount....”
A trial court may properly consider the apparent fairness of a given result when contract language is susceptible of two different interpretations, one of which leads to a reasonable result and the other to an unreasonable result. “ Where language of a contract is open to an interpretation which is reasonable and in accordance with the general purpose of the parties, the hardship of a different interpretation is strong ground for belief that such a meaning was not intended.’ ”
Canaras,
Furthermore, the fact that the cost of a partial release may differ substantially depending on the number of recorded residential lots on the encumbered property is anticipated from the express release language. Indeed, as Judge Kenney noted in his dissent from the Court of Special Appeals’ decision, there may be very practical purposes for drafting the release provision on a per lot basis:
“Under this approach, the mortgage preserves the mortgagee’s security for the outstanding debt while permitting the mortgagor an orderly subdivision and development process. In addition, as the mortgage holder, the mortgagee would be required to execute any plats to be recorded and thereby participate indirectly in the subdivision process. This participation presents to the mortgagee an opportunity to monitor the subdivision process and weigh the resulting impact of such things as any proposed public and private *447 rights-of-way, easements, and possibly reservations of open space, or any other dedications or approval requirements affecting the security and its future subdivision potential.”
The language of the partial release, though perhaps not a model of clarity, unambiguously effectuates this purpose.
IV.
The interpretation of a written contract is legal question subject to de novo review by the appellate courts. Whether a contract’s clear terms resolve a particular ambiguity requires an objective analysis of the contract language considering the respective positions of the contracting parties. A party wishing to introduce extrinsic evidence to show the intent of the contracting parties must propose a plausible interpretation that resolves the specific alleged ambiguities in the contract. The partial release provision at issue in this case states that the amount that must be paid for a partial release from the mortgage is based on a number of residential lots in the mortgaged property at the time the release is sought, i.e., “from time to time.” The language is unambiguous. Moreover, even if the language were ambiguous, parol evidence would be admissible only to resolve the ambiguities and not to contradict unambiguous terms of the contract. The trial court therefore erred by attempting to ascertain the contracting parties’ intent with the use of parol evidence and by not applying the express terms of the partial release provision.
JUDGMENT OF THE COURT OF SPECIAL APPEALS REVERSED, AND CASE REMANDED TO THAT COURT WITH DIRECTIONS TO REVERSE THE JUDGMENT OF THE CIRCUIT COURT FOR HOWARD COUNTY AND REMAND THE CASE TO THAT COURT FOR FURTHER PROCEEDINGS CONSISTENT WITH THIS OPINION. RESPONDENT TO PAY COSTS IN THIS COURT AND IN THE COURT OF SPECIAL APPEALS.
Notes
. Hereinafter, this opinion shall refer to the trustee responsible for enforcing the Simpson mortgage as the “mortgagee.” That trustee currently is Carol L. Calomiris, the Petitioner in this case, but prior trustees were the parties to earlier proceedings in the litigation giving rise to this petition.
. The $752,100 figure appears to be based on 115 percent of the total mortgage of $654,000.
. The different and larger typeface is consistent with provisions obviously inserted into the standard mortgage contract by the contracting parties, including the names of the parties and financial figures.
. We reject without further discussion Woods' contention that this appeal is moot because the mortgagee foreclosed on another lot subject to the same mortgage while this appeal was pending. Counsel for Woods conceded at oral argument that there is no clear rule of law in Maryland that the foreclosure of one lot subject to a mortgage extinguishes that mortgage with respect to another lot which is subject to the same mortgage. Furthermore, the record indicates that Woods did not file any exceptions to the foreclosure action and in fact cooperated with the mortgagee so, as to ensure that the Woods lot was clearly excluded from the foreclosure sale precisely because this petition was pending.
. Motions for summary judgment are governed by Maryland Rule 2-501, which states in pertinent part:
. The alleged ambiguity is in the terms "subdivided lots,” "from time to time,” and "recorded subdivision plat.”
