What Is a Purchase Agreement?

A purchase agreement is the legally binding contract that governs the sale of a home between a buyer and a seller. Once both parties sign it, it is no longer just an offer — it is an enforceable document that defines each party's rights, obligations, and remedies from that moment through closing.

Most states use standardized forms drafted by their real estate associations, but the terms inside those forms are not boilerplate suggestions. Every clause means something specific. Buyers who treat the agreement as a formality to get through quickly are more likely to be surprised — and more likely to be exposed — when complications arise.

This guide defines the terms buyers encounter most often and explains what each one actually requires of you. For contrast on how a seller reads the same document, see our plain-language glossary for home sellers.

Purchase Agreement

The legally binding contract between a buyer and seller that sets the price, terms, and conditions of a home sale. Once signed by both parties, it creates enforceable obligations.

Earnest Money

A good-faith deposit made by the buyer at the time of contract signing. It is held in escrow and applied to closing costs; it may be forfeited if the buyer backs out without a valid contractual reason.

Contingency

A condition written into the contract that must be met for the sale to proceed. Common examples include financing approval, a satisfactory home inspection, and an acceptable appraisal.

Escrow

A neutral third-party account that holds funds — such as the earnest money deposit — until the transaction is complete or the contract is cancelled.

Appraisal

An independent assessment of a property's market value, typically required by a mortgage lender. If the appraised value comes in below the purchase price, it can trigger renegotiation or contract cancellation.

Specific Performance

A legal remedy that compels a party who has breached a contract to fulfill their obligations under it, rather than simply paying damages. More common in commercial real estate than residential transactions.

Inclusions and Exclusions

Contract terms specifying which items — appliances, fixtures, or other personal property — are included in or excluded from the sale. Anything not written into the agreement may be removed by the seller.

Legal Description

The official, recorded identification of a property using lot and block numbers or a metes-and-bounds survey. It is distinct from a street address and used in all legal documents.

Price, Earnest Money, and Financing Terms

The purchase price is the agreed amount you will pay for the property. What follows that number in the contract matters just as much.

Earnest money (also called a good-faith deposit) is the upfront sum — typically 1–3% of the purchase price, though amounts vary by market — that a buyer deposits to show serious intent. It is held in escrow and applied toward your costs at closing. Whether you get it back if the deal falls through depends entirely on the contract terms and why the deal failed.

Financing contingency (see the next section for contingencies broadly) sets out the loan amount, interest rate cap, and loan type you are seeking. If you cannot obtain financing on those terms, this clause allows you to exit without penalty. Pay attention to the deadline: once a financing contingency expires, losing your loan approval no longer protects your deposit.

Down payment is the portion of the purchase price not covered by your mortgage. The contract specifies when it must be delivered and in what form — personal checks are rarely accepted at closing.

Once you understand these financial terms, the closing costs breakdown is a logical next step to budgeting the full cost of the transaction.

Contingencies: Your Built-In Protections

Contingencies are conditions that must be satisfied — or formally waived — before the sale can close. They are your primary exit ramps if something goes wrong. The three most common are:

  • Inspection contingency: Gives buyers a set window (often 7–14 days) to have the property professionally inspected. If the inspection reveals material issues, the buyer can request repairs, negotiate a price reduction, or walk away.
  • Financing contingency: Protects you if your mortgage falls through. As noted above, the deadline is critical — don't let it expire before your lender has issued a clear-to-close.
  • Appraisal contingency: If the home appraises below the agreed purchase price, this clause lets you renegotiate or exit. Without it, you may be obligated to pay the difference between the appraised value and the contract price out of pocket.

Some buyers waive contingencies in competitive markets to make their offers more attractive to sellers. Doing so significantly increases financial risk. Consult your agent and, if applicable, a real estate attorney before agreeing to waive any contingency. For the seller's perspective on these same clauses, see our guide on how home sale negotiations unfold.

Key Dates and What Happens If You Miss Them

Purchase agreements are built around deadlines, and most include a "time is of the essence" clause — meaning all dates are strict and legally material. Missing a deadline is not a minor oversight; it can constitute a breach of contract.

Watch for these critical dates:

  • Inspection period end date: The last day you can submit an inspection objection or waiver.
  • Financing contingency deadline: The date by which you must have secured your loan commitment.
  • Appraisal contingency deadline: When the appraisal must be completed and any objection filed.
  • Closing date: The agreed date of final settlement. Extensions are possible but require written agreement from both parties.

Track Every Deadline from Day One

The moment you go under contract, create a calendar with every date from the agreement — inspection deadline, financing deadline, appraisal deadline, and closing date. Share those dates with your lender, agent, and attorney on the same day. In most contracts, missed deadlines cannot be reversed without the seller's written consent, and some can cost you your deposit.

Build a personal calendar with all contract dates the day you go under contract. Relay them to your lender, agent, and attorney immediately so no deadline is missed due to a scheduling gap.

What the Agreement Says About the Property Itself

Two underread sections define exactly what you are buying: inclusions and exclusions, and the property description.

Inclusions list fixtures and personal property that convey with the home — appliances, light fixtures, window treatments, and similar items the seller has agreed to leave behind. Exclusions are items the seller intends to remove, even if they appear to be part of the home (a mounted flat-screen TV or a built-in bookshelf, for example). If it matters to you, get it in writing.

The legal description of the property — typically a lot and block number or metes-and-bounds description — is the official identification of the parcel being transferred. This should match the title commitment and deed exactly.

Purchase agreements also reference seller disclosures, separate documents where sellers report known defects, prior repairs, and material conditions. These disclosures vary by state. For a detailed look at what sellers are typically required to reveal, see our article on seller disclosure obligations.

Default, Remedies, and Backing Out

The default and remedies section explains what happens if either party fails to perform. For buyers, the most common consequence of default is forfeiture of the earnest money deposit. In some states and contracts, sellers may also pursue specific performance — a legal action requiring the buyer to complete the purchase — though this is less common in residential transactions.

If the seller defaults (for example, by refusing to close or accepting a higher offer after signing), the buyer is generally entitled to a refund of earnest money and, in some cases, may pursue damages or specific performance.

Mutual rescission is when both parties agree in writing to cancel the contract. This is the cleanest exit and typically results in the buyer receiving their earnest money back.

Reading a purchase agreement carefully is similar in discipline — if different in stakes — to reviewing any dense legal document before you sign. If you are renting rather than buying, the same due-diligence habit applies: our guide on how to read and negotiate a lease walks through that parallel process.
