To write a purchase agreement, put the deal in writing with the parties and asset identified precisely, the price and payment terms stated as specific numbers and dates, the contingencies that let either side walk tied to hard deadlines, the protective boilerplate that courts expect, and signatures from everyone bound by it. The document can be two pages or two hundred depending on what’s changing hands, but the same core pieces have to be present or you have an enforceability problem.
One threshold point before drafting: every state has a statute of frauds requiring certain contracts to be in writing. Real estate purchase agreements always fall under this rule, and the Uniform Commercial Code pulls in sales of goods at or above $500, which covers most vehicle and equipment deals. A handshake on a house is worthless in court no matter how many people saw it. Email chains and text messages can technically satisfy the writing requirement in some jurisdictions, but relying on that is a gamble. Draft the agreement.
Gather Your Inputs Before You Start Drafting
Collect everything the document will need before you open the template. Drafting from a half-filled folder produces a half-filled contract.
- Full legal names, addresses, and contact details for every buyer and seller. If a business entity is on either side, use the entity’s registered legal name and identify the person authorized to sign for it.
- A precise description of the asset. For real estate, that means the physical address, the legal description from the deed, and the parcel number. For a vehicle, the year, make, model, and VIN. For a business, a clear definition of what’s being transferred: assets, stock, or both.
- The agreed price, how and when it will be paid, any deposit or earnest money, and the financing arrangement if the buyer is borrowing.
- Specific calendar dates for every contingency — inspection, appraisal, loan approval, closing.
- A list of what’s included and what isn’t. Appliances, fixtures, inventory, equipment. Ambiguity here generates more disputes than almost any other part of the agreement.
- For real estate, confirmation of the seller’s title and a search for liens, easements, or other encumbrances. Outstanding mortgages, tax liens, and use restrictions can derail a deal after closing if they weren’t caught before signing.
Identify the Parties and the Asset
Open the agreement by naming the buyer and seller with their full legal names. No nicknames, no informal business names. If a party is an LLC or corporation, use the registered name exactly as it appears on the entity’s formation documents.
Then describe what’s being sold with enough detail that someone unfamiliar with the deal would know exactly what’s changing hands. For real estate, use the legal description from the deed, not just the street address. Street addresses get ambiguous when properties share a lot or have been subdivided, and the legal description is what ties the contract to a specific parcel of land.
State the Price, Payment Structure, and Financing
Write the total purchase price as a specific dollar amount. Then spell out the payment structure in the same specific terms. If the buyer is making a deposit and financing the rest, say how much the deposit is, when it’s due, and what type of loan the buyer is pursuing. Vague language like “buyer will arrange financing” invites problems; specify the loan type, the maximum interest rate the buyer will accept, and the deadline for securing a loan commitment.
If the seller is carrying a note instead of the buyer going to a bank, include the interest rate, the repayment schedule, and the consequences of default on the note.
Write Representations and Warranties for Both Sides
Each side makes factual statements about itself and the asset. The seller typically represents that they hold clear title, that they’ve disclosed known defects, and that they have authority to sell. The buyer typically represents that they have the financial capacity to close. These aren’t formalities. If a representation turns out to be false, the other party can use it as grounds to cancel the deal or sue for damages after closing.
Build In Contingencies With Hard Deadlines
Contingencies are escape hatches that let a party walk away without penalty if a specific condition isn’t met by a specific date. The ones that show up in most real estate purchase agreements are:
- A financing contingency, giving the buyer until a set date to obtain a mortgage commitment. If the loan falls through, the buyer can cancel and recover the earnest money.
- An inspection contingency, usually a window of 7 to 14 days for the buyer to hire an inspector and review the property’s condition. If serious defects surface, the buyer can renegotiate or exit.
- An appraisal contingency, so a buyer whose lender’s appraisal comes in low can renegotiate or cancel rather than overpay.
- A title contingency, conditioning the deal on the seller delivering clear title free of undisclosed liens or encumbrances.
Every contingency needs a hard calendar deadline in the contract. In many agreements, a contingency that expires without the buyer acting is treated as waived; at that point the buyer is locked in, and walking away means forfeiting the earnest money or facing a breach claim. Open-ended contingency language is the drafting error that produces the most expensive disputes.
Spell Out Earnest Money and Default Consequences
Earnest money is the buyer’s deposit showing they’re serious about the purchase. In most real estate transactions it runs between 1% and 3% of the purchase price, though sellers in competitive markets sometimes expect more. The agreement should specify the exact amount, who holds it in escrow (typically a title company or the seller’s attorney), and the conditions for releasing it to the seller or refunding it to the buyer.
Default provisions are where this gets consequential. Most purchase agreements include a liquidated damages clause stating that if the buyer backs out without a valid contingency, the seller keeps the earnest money as their sole remedy. The clause exists because calculating a seller’s actual losses from a failed deal is hard: lost time, a stale listing, maybe a lower eventual sale price. The earnest money becomes the agreed estimate of those damages.
On the seller’s side, if the seller defaults, the buyer typically has the right to seek either return of the earnest money plus damages or, in the case of real estate, specific performance — a court order forcing the seller to go through with the sale.
Add the Protective Clauses DIY Drafts Usually Miss
Merger Clause
A merger clause (sometimes called an integration clause) states that the written agreement is the entire deal between the parties and supersedes everything discussed during negotiations. Without it, a party might try to enforce a verbal promise that never made it into the final document. If it’s not in the written contract, it doesn’t exist. This is one of the most frequently omitted provisions in homemade purchase agreements, and its absence creates avoidable litigation.
Assignment Restrictions
An assignment clause controls whether either party can transfer their rights under the contract to someone else. In many jurisdictions, the default rule allows assignment, which means your carefully chosen buyer could hand the contract to a third party you’ve never met. Most purchase agreements restrict assignment by requiring written consent from the other party before any transfer. A seller who agreed to sell to a specific buyer wants this clause.
Force Majeure
A force majeure clause excuses performance when extraordinary events beyond either party’s control prevent closing — natural disasters, government orders, widespread emergencies. Without one, a party who can’t close because of circumstances completely outside their control could still be held in breach. These provisions are standard in commercial and business acquisition agreements and worth considering in residential deals with long closing timelines.
Dispute Resolution
Specify how disagreements will be handled before they arise. The usual options are mediation (a neutral helps negotiate a resolution), arbitration (a neutral makes a binding decision), or litigation in a named court. Many purchase agreements require mediation as a first step with arbitration or litigation as fallbacks. Arbitration can be faster and cheaper than court, but it limits appeal rights. Whatever you choose, name the process in the contract so neither party is guessing after a dispute surfaces.
Write In Plain, Specific Language
Templates are a reasonable starting point for straightforward transactions, but no template perfectly fits your deal. After plugging in names, property descriptions, and financial terms, go through every boilerplate clause and ask whether it actually applies. A template written for a cash purchase won’t have adequate financing contingency language. A template designed for residential real estate won’t address inventory, intellectual property, or employee agreements in a business acquisition.
“The seller will leave the property in good condition” means something different to every person who reads it. “The seller will deliver the property in broom-clean condition, with all debris removed and all systems in working order as of the final walkthrough” means the same thing to everyone. Ambiguity in a purchase agreement doesn’t create flexibility. It creates arguments.
Dates deserve the same discipline. Every deadline should be a specific calendar date rather than a relative timeframe like “within 30 days.” Relative timeframes invite disputes about when the clock started. If you do use them, define the trigger event clearly: “within 14 calendar days of the effective date” is better than “within two weeks of signing,” since not all parties sign on the same day.
Federal Rules That Apply to Residential Real Estate
If the agreement involves residential property built before 1978, federal law requires the seller to disclose any known lead-based paint hazards before the buyer is obligated under the contract. The seller must provide any available lead inspection reports and give the buyer at least 10 days to conduct an independent lead inspection unless both parties agree to a different timeframe. The contract itself must include a specific Lead Warning Statement, and the buyer must sign an acknowledgment confirming they received the required disclosures and had the opportunity to inspect.1Office of the Law Revision Counsel. 42 USC 4852d – Disclosure of Information Concerning Lead Upon Transfer of Residential Property
Review, Sign, and Distribute Copies
Before anyone signs, have an attorney review the document. This is not the place to save money. An attorney catches problems that don’t look like problems to a non-lawyer: missing contingencies, unenforceable clauses, exposure you didn’t know you were accepting. The cost of a contract review is a fraction of the cost of litigating a flawed agreement.
Execution requires every party to sign and date the document. The contract is generally not binding until all parties have signed. In some jurisdictions, real estate purchase agreements also require notarization, particularly if the document will be recorded with the county.
Electronic signatures carry the same legal weight as handwritten signatures for most purchase agreements under federal law. The E-SIGN Act provides that a contract cannot be denied legal effect solely because an electronic signature was used in its formation.2Office of the Law Revision Counsel. 15 USC 7001 – General Rule of Validity For an electronic signature to hold up, the signer must consent to conducting business electronically, the signature must be clearly linked to the specific document, and there must be a reliable way to retain and reproduce the signed record. A few narrow categories of documents, including wills, certain family law documents, and court orders, are excluded from the E-SIGN Act and still require ink signatures.
After execution, make sure every party receives a fully signed copy. Deals regularly close with one side holding an incomplete set of documents. A signed copy is your proof that the contract exists and what it says.
What Each Side Is Risking Once It’s Signed
If the buyer breaches, typically by refusing to close without a valid contingency, the seller’s primary remedy under most purchase agreements is retaining the earnest money as liquidated damages. Some agreements give the seller the option to pursue actual damages in court instead, but liquidated damages clauses often make the earnest money the seller’s exclusive remedy.
If the seller breaches by refusing to sell, selling to someone else, or failing to deliver clear title, the buyer can seek money damages or ask a court for specific performance. Courts are more willing to grant specific performance in real estate disputes than in other contract disputes because every piece of property is considered unique, and money alone can’t fully compensate a buyer who loses a specific home or commercial location they contracted to purchase.
Know your exposure before signing. For the buyer, the earnest money is at risk the moment the contingencies expire. For the seller, accepting an offer and signing means a court can force you to follow through.
