Key Takeaways

  • The purchase agreement is the central contract specifying price, terms, contingencies, and closing conditions.
  • Option contracts give the right but not the obligation to purchase; forfeiture of the option fee is the maximum risk.
  • Rights of first refusal allow matching third-party offers but can deter potential buyers.
  • Installment contracts carry significant forfeiture risk for buyers in many states.
  • Lease-options combine occupancy with a future purchase right, useful for buyers building credit or savings.
  • Land contract (contract for deed) buyers face forfeiture risk in many states — some states allow sellers to retain all payments made if the buyer defaults, even after years of payments.

Real estate contracts come in several forms, each serving a different purpose in the transaction process. The purchase agreement is the central contract in most residential transactions, but option contracts, installment contracts, and lease-option agreements each play important roles in specific situations.

The Purchase Agreement

The purchase agreement (also called a contract of sale, sales contract, or purchase and sale agreement) is the central contract governing the sale of real property. It establishes the terms and conditions under which the buyer agrees to purchase and the seller agrees to sell the property. Key provisions include: identification of the parties and property, purchase price and payment terms, earnest money amount and disposition, financing contingency, inspection contingency, appraisal contingency, closing date, possession date, included and excluded items, and default remedies.

Purchase agreements are typically prepared on standardized forms approved by state or local real estate associations, with fill-in-the-blank fields for transaction-specific terms. Agents must complete these forms accurately and completely — errors in dates, dollar amounts, property descriptions, or contingency terms can create ambiguity that leads to disputes. Any provisions that cannot be accommodated by the standard form should be addressed through addenda or amendments reviewed by legal counsel.

Each contract type carries distinct risk profiles for buyers and sellers. The appropriate contract depends on the parties' financial situation, risk tolerance, and transaction objectives.

Option Contracts and Right of First Refusal

An option contract gives one party (the optionee) the right, but not the obligation, to purchase property at a specified price within a specified time period. The optionee pays an option fee (option consideration) for this right. If the optionee exercises the option, the parties proceed to close under the terms specified in the option agreement. If the optionee does not exercise the option before it expires, the option fee is typically forfeited to the property owner.

A right of first refusal (ROFR) is different from an option: it gives the holder the right to match any offer the property owner receives from a third party. The ROFR does not give the holder the right to purchase at any time — only the right to match a specific offer. ROFRs are common in commercial leases, partnership agreements, and HOA governing documents. From a seller's perspective, a ROFR can deter potential buyers who may not want to invest time and money in due diligence knowing that another party can match their offer.

Installment Contracts and Lease-Options

An installment contract (also called a land contract, contract for deed, or agreement for deed) is a financing arrangement in which the seller finances the purchase directly. The buyer makes installment payments to the seller and receives equitable title (the right to possess and use the property), but the seller retains legal title until the buyer has completed all payments. Installment contracts are used when buyers cannot qualify for traditional financing, but they carry significant risks for buyers in states where forfeiture provisions allow the seller to terminate the contract and retain all payments if the buyer defaults.

A lease-option combines a lease with an option to purchase. The tenant pays rent and an additional option fee that gives them the right to purchase the property at a specified price during or at the end of the lease term. Lease-options are popular in markets where buyers need time to improve their credit, save for a down payment, or evaluate a neighborhood. A portion of the rent may be credited toward the purchase price if the option is exercised.

Common Mistakes to Avoid

Confusing a right of first refusal with an option contract.

Consequence: A right of first refusal only gives the holder the right to match another offer, while an option gives the right to purchase at set terms regardless of other offers.

Correction: Understand that a right of first refusal is triggered only when the owner receives an offer from a third party, while an option can be exercised at any time during the option period.

Using non-standard or homemade purchase agreement forms instead of state-approved or attorney-reviewed forms.

Consequence: Missing essential clauses, improper legal language, or regulatory non-compliance that can render the contract unenforceable or create liability.

Correction: Use state-approved, association-provided, or attorney-reviewed contract forms. Only modify standard forms under attorney guidance.
