Between an accepted offer and the closing table, a home sale is governed by one document: the purchase agreement. That contract decides who holds the earnest money, which problems let the buyer walk away, what the seller must reveal about the property, and what happens if either side breaks its promises. Buyers and sellers who understand those moving parts before signing are far less likely to lose a deposit — or a deal — over a clause they never read.
Real estate contracts are creatures of state law, so forms and customs differ from state to state, and even between regions of the same state. What follows covers the framework most transactions share, plus the federal disclosure rules that apply nationwide.
Key takeaways
- Under each state's statute of frauds, a contract to sell land must be in writing and signed to be enforceable.
- Contingencies — inspection, financing, appraisal, title, and sometimes home-sale — are the buyer's lawful exits; missing a contingency deadline can forfeit them.
- Most states require sellers to complete a written property-condition disclosure, and federal law adds a lead-paint disclosure for homes built before 1978.
- For most mortgage borrowers, federal TRID rules require a Loan Estimate within three business days of application and a Closing Disclosure at least three business days before closing.
- Earnest money disputes, missed deadlines, and disclosure fights are the most common ways deals turn into litigation — nearly all are avoidable with calendar discipline.
From offer to binding contract
An offer becomes a contract when the other side accepts it without changes and acceptance is communicated. Because land is involved, the statute of frauds in every state requires the agreement to be in writing and signed by the party against whom it is enforced. Handshake deals over houses are, with narrow exceptions, unenforceable.
A complete purchase agreement typically identifies the parties and the property, states the price and how it will be paid, sets the closing date, lists what personal property stays, allocates closing costs, and spells out contingencies and remedies. Many of the risk-allocation ideas — deadlines that are "of the essence," notice provisions, default remedies — echo concepts found in ordinary business contracts, but here they are applied to the largest purchase most people ever make.
Earnest money
Earnest money is a deposit, commonly held in escrow by a title company, broker, or attorney, that shows the buyer is serious. If the buyer properly cancels under a contingency, it is refunded. If the buyer defaults without a contractual excuse, the contract usually lets the seller keep it as liquidated damages. Who holds the deposit and exactly when it becomes nonrefundable are negotiated terms — read them closely.
Contingencies: the buyer's exit doors
A contingency is a condition that must be satisfied — or waived — before the parties are fully bound. Each one carries a deadline, and the deadline is the whole game: let it pass silently and, under most forms, the contingency is deemed waived.
- Inspection contingency. The buyer may hire inspectors within a set window (often 7–14 days) and can cancel, or negotiate repairs or credits, based on the findings.
- Financing contingency. The deal depends on the buyer obtaining a loan on described terms by a stated date; if a diligent buyer cannot, the deposit comes back.
- Appraisal contingency. If the lender's appraisal comes in below the price, the buyer can renegotiate or exit rather than bring extra cash.
- Title contingency. The buyer may object to liens, easements, or other defects shown in the title commitment; the seller usually gets a chance to cure.
- Home-sale contingency. Less common in hot markets: the purchase depends on the buyer selling a current home first.
Watch the deadline: Contingency periods run from precise trigger dates defined in the contract — often the "effective date" of full execution, not the day you agreed on price. Calendar every deadline the day the contract is signed, and get any extension in writing before the period expires.
What sellers must disclose
Most states have moved away from pure "buyer beware" and require sellers of residential property to complete a written disclosure form covering known material defects — roof leaks, foundation problems, water intrusion, unpermitted work, and similar issues. A minority of states still follow more caveat-emptor-flavored rules, though even there sellers generally may not actively conceal defects or lie when asked. The form, the covered topics, and the consequences of nondisclosure are all state-specific, so check your state's required form and your local practice. Local land-use status can matter too: unpermitted additions or a use that violates zoning rules is exactly the kind of issue disclosure fights are made of.
The federal lead-paint disclosure
One disclosure applies nationwide. For most housing built before 1978, federal law requires sellers (and landlords) to give buyers the EPA pamphlet "Protect Your Family From Lead In Your Home," disclose any known lead-based paint or hazards along with available records, and include a lead warning statement in the contract. Buyers must also receive a 10-day window to conduct a lead inspection or risk assessment, although the parties can shorten, extend, or waive it in writing. The rule, described on the EPA's lead disclosure page, does not force anyone to test or remove lead paint — it forces information into the open, and violations can bring significant penalties.
Financing and the federal disclosure clock
Where the buyer uses a mortgage, a parallel set of federal consumer-protection deadlines runs alongside the contract. Under the TILA-RESPA Integrated Disclosure rule ("TRID"), administered by the Consumer Financial Protection Bureau:
- The lender must deliver a Loan Estimate within three business days of a completed application, summarizing the rate, monthly payment, and closing costs so borrowers can comparison-shop.
- The lender must deliver a Closing Disclosure at least three business days before consummation, showing the final loan terms and an itemized settlement statement. The CFPB advises borrowers who do not receive it on time to demand it before signing.
- Certain last-minute changes — an interest-rate increase beyond specified tolerances, a change in loan product, or a newly added prepayment penalty — restart the three-business-day review period.
These timing rules are one reason closing dates slip. A contract that treats the closing date flexibly ("on or about") absorbs a disclosure-triggered delay better than one where time is strictly of the essence.
The path to closing day
- Contract effective date. All parties have signed; contingency clocks start; earnest money is deposited in escrow.
- Inspections and negotiations. The buyer inspects, then cancels, proceeds, or negotiates repairs or credits within the inspection window.
- Title and survey review. The title company or attorney issues a commitment; the buyer objects to defects; the seller cures or the parties adjust.
- Loan approval and appraisal. Underwriting finishes; the appraisal is delivered; the financing contingency is satisfied or invoked.
- Closing Disclosure review. At least three business days before closing, the borrower reviews final numbers against the Loan Estimate.
- Closing and recording. Deed and loan documents are signed, funds move through escrow, and the deed is recorded. Depending on the state, an attorney, title company, or escrow agent runs the table.
State custom varies here more than anywhere else: several states require or customarily use attorneys to conduct closings, while others rely almost entirely on title or escrow companies. If the property will not be owner-occupied at closing — say the seller leases it back for a month, or tenants remain in place — the parties are stepping into landlord–tenant territory and should document that arrangement separately and carefully.
When deals fall apart
Most failed contracts end quietly: a contingency is invoked on time, the escrow agent refunds the deposit, and everyone moves on. Disputes arise when a party misses a deadline, cancels for a reason the contract does not cover, or when a buyer discovers post-closing defects they believe the seller knew about. Typical remedies include retention or refund of the earnest money, damages, and — because land is legally unique — the possibility of a court ordering specific performance of the sale. Sales out of an estate add another layer, since the personal representative's authority to sign may depend on where the probate process stands.
Example (hypothetical): A buyer's inspection reveals an aging furnace, but the buyer emails a repair request two days after the inspection period ended. Under many form contracts, the contingency was already waived, so the seller may refuse repairs and keep the deal — and, if the buyer walks, the deposit. The substance of the complaint mattered less than the calendar.
Frequently asked questions
Can a buyer back out after signing a purchase agreement?
Only through a door the contract provides. A buyer who cancels within a valid contingency period — inspection, financing, appraisal, or title — typically recovers the earnest money. Canceling without a contractual basis is a default, which usually costs the deposit and can, in some states, expose the buyer to further damages or a specific-performance claim.
Is a verbal agreement to sell a house enforceable?
Almost never. State statutes of frauds require contracts for the sale of land to be in writing and signed. Narrow exceptions exist — such as part performance, where a buyer has taken possession and made improvements in reliance on an oral deal — but they are litigated rarities, not a plan.
What happens if the seller did not disclose a known defect?
Depending on the state, a buyer may have claims for breach of the disclosure statute, fraud, or misrepresentation, with remedies ranging from repair costs to rescission of the sale. Success usually requires showing the seller actually knew about the defect and that the buyer could not reasonably have discovered it. Deadlines to sue are state-specific and can be short.
Do I need an attorney to buy a house?
It depends on where you are. Some states require or customarily involve attorneys in residential closings; in others, licensed title or escrow companies handle nearly everything and buyers hire counsel only for unusual issues — estate sales, boundary problems, for-sale-by-owner deals, or heavily negotiated terms. When the contract deviates from the standard state form, a legal review is money well spent.
Before you sign: a short discipline
Three habits prevent most residential contract disputes. First, treat the contract as a set of clocks: list every deadline, who must act, and what silence costs. Second, put every change in writing — repair agreements, extensions, and credits included — because oral side deals about land are generally worthless. Third, read every disclosure and every federal loan document when it arrives, not at the signing table; the three-day Closing Disclosure window exists precisely so you can catch errors while they are still fixable.
