How to Write a Real Estate Purchase Agreement in the United States (2026): Contingencies, Earnest Money and Closing

A real estate purchase agreement is a binding contract between a buyer and seller that locks in the price, earnest money amount, contingency deadlines, and closing date for a residential property. Without it, neither party has enforceable obligations. Every US state recognizes this type of contract under its own version of the Statute of Frauds — real property transfers must be in writing to be enforceable, a principle codified federally in the context of fair housing and disclosure law, and individually in statutes like California Civil Code §1624 and New York's General Obligations Law §5-703.

What a purchase agreement actually is — and what it isn't

A purchase agreement is not a deed, a title transfer, or a mortgage. Signing it does not move ownership. The agreement creates the framework: it tells escrow what terms to execute, tells the lender what amount to underwrite, and gives both parties specific exit rights if conditions go unmet. The deed transfers at closing; the purchase agreement governs everything between offer and close.

Buyers and sellers sometimes confuse it with an offer letter. An offer letter is a preliminary signal of intent with minimal binding force. Once both parties sign the purchase agreement, it becomes a full contract. Oral modifications made after signing are unenforceable in most states — changes require a written addendum signed by both sides.

The core sections every agreement needs

Identification of parties and property. Names must match government IDs and the title chain exactly. The property is described by its full legal description (lot, block, subdivision, or metes-and-bounds), not just the street address. A mismatch here can delay title clearance at closing.

Purchase price and financing terms. State the total price, the amount of the buyer's earnest money deposit, whether the buyer is financing or paying cash, and the name of the lender if applicable. If the buyer is applying for a mortgage, include the loan type (conventional, FHA, VA), the maximum interest rate the buyer will accept, and the number of days allowed to obtain loan commitment.

Earnest money terms. Earnest money — typically 1 to 3 percent of the purchase price — shows the seller the buyer is serious. The deposit goes into an escrow account held by the title company or a licensed escrow agent. Specify: the amount, the deadline for deposit (usually 3 business days after contract execution), and exactly who holds the funds. State what triggers forfeiture: if a buyer walks away without a contractual basis, the seller generally keeps the deposit. If the seller backs out, the buyer typically gets the earnest money back plus may sue for specific performance under state contract law.

Contingencies. These are the clauses that let a party exit without penalty. Three appear in nearly every residential deal:

• Inspection contingency — the buyer has a specified window (often 10 calendar days) to complete a professional home inspection. If defects exceed a threshold or the buyer simply objects to findings, the buyer can request repairs, accept a price reduction, or terminate.
• Financing contingency — if the buyer cannot secure a mortgage commitment meeting the terms specified in the agreement by the deadline (typically 21 days), the buyer can terminate and recover the earnest money deposit.
• Title contingency — the seller must deliver clear, marketable title at closing. Title is searched by a licensed title company, and any clouds (unpaid liens, easement disputes, boundary conflicts) must be resolved. Under the American Land Title Association (ALTA) standards, a title commitment is issued before closing.

Some agreements also include an appraisal contingency — particularly common in FHA and VA transactions — that lets the buyer renegotiate or exit if the appraised value comes in below the purchase price.

What to do about disclosure requirements

Federal law under RESPA (Real Estate Settlement Procedures Act, 12 USC §2601) and the Dodd-Frank Act requires lenders to provide a Loan Estimate within 3 business days of application and a Closing Disclosure 3 business days before closing. Those are lender obligations, but the purchase agreement should align its timeline with those windows to avoid conflicts.

State-level seller disclosure requirements vary sharply. California requires sellers to complete the Transfer Disclosure Statement (TDS) under Civil Code §1102 as soon as practicable before transfer of title (the standard C.A.R. contract sets a 7-day delivery window from acceptance). New York requires the Property Condition Disclosure Act form under Real Property Law §462. Texas mandates Seller's Disclosure Notice under §5.008 of the Property Code. If the agreement doesn't reference these disclosures, or doesn't set a deadline for delivery, disputes about what the buyer knew and when become messy.

Closing date, possession, and prorations

The closing date is the calendar day when title transfers, funds settle, and keys change hands. The agreement should specify whether "closing" means the day documents are signed, the day the deed is recorded with the county, or the day funds are wired. In wet-funding states (California, for example), all documents are signed and funds distributed on the same day. In dry-funding states (Oregon, Washington), there is a one-day gap.

Possession may not coincide with closing. Some sellers negotiate a rent-back period: they close, the buyer becomes the new owner, but the seller stays in the home for 30 to 60 days while finding their next place. A rent-back clause should specify the daily occupancy fee, who carries insurance, and what happens if the seller holds over.

Prorations settle property taxes, HOA dues, and prepaid utilities between the parties as of the closing date. The agreement should state whether prorations are calculated on a 360-day or 365-day year, and who is responsible for any supplemental tax bill issued after closing.

Drafting the contingency deadlines: a practical timeline

For a 30-day close, a workable contingency timeline looks like this:

• Day 1–3: earnest money deposited into escrow
• Day 1–10: buyer schedules and completes home inspection; delivers written notice of any objections
• Day 10–14: seller responds to repair requests; parties negotiate addendum or buyer terminates
• Day 1–21: buyer submits mortgage application; lender issues Loan Commitment
• Day 21: financing contingency deadline; buyer removes or invokes
• Day 1–25: title company delivers title commitment; buyer reviews exceptions
• Day 28: final walkthrough (buyer inspects property one last time before closing)
• Day 30: closing

Deadlines that are too short create problems. A 7-day inspection window sounds efficient until a busy inspector can't schedule until day 6. Build in realistic buffer for each contingency, and specify whether days are calendar days or business days — this matters, particularly around weekends and federal holidays.

Common mistakes that kill deals at closing

Not specifying personal property. Unless the agreement explicitly lists what stays with the house (built-in appliances, fixtures, window treatments, garage shelving), the general rule is that fixtures are real property and convey with the house, while personal property does not. A ceiling fan is a fixture. A free-standing refrigerator is personal property. When there's ambiguity, disputes erupt at closing.

Vague repair language. "Seller agrees to repair the roof" is unenforceable as written. "Seller agrees to replace damaged shingles identified in Section 4.B of the inspection report by a licensed roofing contractor and deliver a paid invoice at closing" is enforceable.

Skipping the escalation clause in competitive markets. In multiple-offer situations, an escalation clause lets the buyer automatically beat competing offers by a set increment (say, $2,000) up to a ceiling price. Without one, buyers either overpay from the start or lose to a competitor by $500.

Using a generic national form without state-specific riders. Most state Realtor associations publish jurisdiction-specific standard forms. In Florida, the FAR-BAR contracts include riders for condominiums and flood zone disclosure under §689.302. A generic contract that omits state-required provisions can create real liability.

Where to find a ready-to-use template

Most buyers and sellers start with a template and then customize it. Forms-legal.com offers a free US real estate purchase agreement template that covers the core contingencies, earnest money terms, and closing provisions discussed here. A template is a starting point — a real estate attorney in your state should review the final document, particularly if the deal involves seller financing or the property has known title issues.

Signing, execution, and what happens next

Both parties must sign for the agreement to be binding. In most states, electronic signatures are valid under the Uniform Electronic Transactions Act (UETA), adopted in 49 states, and the federal E-SIGN Act (15 USC §7001). DocuSign and Adobe Sign are used routinely in residential deals.

Once fully executed, the buyer's agent delivers the agreement to the title company or escrow officer who opens escrow. The lender gets a copy to begin underwriting. Every subsequent action — inspections, repair requests, appraisals, insurance binders — runs against the contractual deadlines. Missing a deadline by even one day, without a written extension addendum, can extinguish a contingency right entirely.

Keep copies of every signed addendum, extension, and waiver. If a dispute arises after closing — about undisclosed defects or personal property left behind — the written record is what courts examine.
