A real estate contract works by putting the entire deal in writing: it names the buyer and seller, identifies the property, locks in the price, sets the deposit, and lists the conditions each side has to meet before ownership can transfer. Once both parties sign, that document controls every step from offer to closing, including what happens if the deal falls apart. Everything else in the transaction, from the inspection to the final wire of funds, flows from what the contract says.
What Makes the Contract Legally Binding
Every state requires real estate sale agreements to be in writing. The rule is called the Statute of Frauds, and it exists because courts will not enforce verbal promises to buy or sell land. A handshake deal carries no legal weight, no matter how detailed the conversation was. The writing requirement covers every transfer of an interest in real property, including sales, leases, and easements.
Beyond the writing itself, a valid contract needs four things. Both parties have to genuinely agree to the same terms, meaning the seller accepts the buyer’s offer without changing the price, closing date, or other material terms. Both sides have to exchange something of value, which in a sale is the buyer’s money (or promise to pay) in return for the seller’s promise to transfer ownership. Everyone signing has to have legal capacity, which generally means being mentally competent and at least 18 years old, though a few states set the age at 19. And the underlying transaction has to be lawful.
Most contracts today are signed electronically. Federal law protects this: under the Electronic Signatures in Global and National Commerce Act, a contract or signature cannot be denied legal effect simply because it is in electronic form.1Office of the Law Revision Counsel. 15 U.S.C. 7001 – General Rule of Validity Platforms like DocuSign and DotLoop are standard, and the signatures they capture carry the same weight as ink on paper.
Key Terms the Contract Has to Spell Out
The full legal names of every buyer and seller must appear exactly as they will appear on the deed. Mismatched names create title problems that can delay or block closing. If you are buying through an LLC or a trust, both the entity name and the authorized signer’s name need to be in the document.
A street address is not enough to legally identify the property. The contract needs the formal legal description from the existing deed or the county tax records, typically a metes-and-bounds description or a lot-and-block reference tied to a recorded plat. If that description is vague or wrong, the contract can be challenged as unenforceable, leaving the buyer without the property and out of pocket for expenses already incurred.
The purchase price has to be stated clearly, usually in both numbers and words to prevent clerical errors from turning into disputes. Alongside the price, the contract spells out the earnest money deposit, which generally runs between 1% and 3% of the purchase price. The deposit signals commitment and goes to a neutral third party, usually a title company or escrow agent, who holds it until closing. The contract should name that escrow holder and set a deadline for delivering the funds. Missing the deadline can put the buyer in breach before the deal has really started.
The contract also has to say exactly when the buyer takes physical possession. That often matches the closing date, but not always. A seller might negotiate a rent-back to stay in the home for a week or two after closing, or a buyer might ask for early access. Both scenarios create risk, so whenever the possession date differs from closing, the contract should address insurance, daily rent, and a hard deadline for the occupant to leave.
One frequently overlooked area is which items stay with the property. Built-in bookshelves, a mounted TV bracket, a chandelier, custom window treatments: disputes over items like these are among the most common post-closing complaints. The general rule is that anything physically attached to the property transfers with the home, while freestanding items go with the seller. The line is not always obvious, so the smartest approach is to list specific items the buyer expects to receive and anything the seller plans to remove. What the contract says overrides the general rule.
Contingencies: Your Exits From the Deal
Contingencies are conditions that have to be satisfied by a certain date. If a condition is not met, the buyer can walk away and get the earnest money back. Without contingencies, backing out usually means forfeiting the deposit.
Inspection Contingency
This gives the buyer a window, commonly seven to fourteen days, to hire a professional inspector. If the inspector finds serious problems like foundation cracks, a failing roof, or outdated electrical wiring, the buyer can request repairs, negotiate a price reduction, or cancel the contract. Skipping the inspection is a gamble that rarely pays off, even in competitive markets.
Financing Contingency
Unless you are paying cash, this clause makes the deal conditional on securing a mortgage commitment by a specific date. If the lender denies the loan, you can cancel without penalty. The contract typically specifies the loan type, an interest rate ceiling, and an approval deadline. Waiving financing means you are on the hook for the full purchase even if your loan falls through.
Appraisal Contingency
Most lenders will not fund a loan for more than the property’s appraised value. If a licensed appraiser determines the home is worth less than the agreed price, this contingency lets you renegotiate the price, pay the difference out of pocket, or cancel. Without it, you have to cover the gap yourself, which can mean tens of thousands of dollars at the last minute.
Title Contingency
The seller has to deliver clear ownership, meaning no outstanding liens, tax debts, or legal claims against the property. A title company searches public records to verify this. If the search turns up a contractor’s lien or a judgment from a prior lawsuit, the seller must resolve it before closing. Title insurance, which the buyer typically purchases at closing, protects against defects the search might have missed.
Home Sale Contingency
Buyers who need to sell their current home first sometimes include this clause, making the purchase conditional on their existing property closing by a certain date. Sellers tend to dislike it and often insist on a kick-out clause that lets them keep the home on the market. If a better offer comes in, the original buyer typically gets 72 hours to either drop the contingency or walk away.
Federal Rules That Attach to the Contract Automatically
Lead-Based Paint Disclosure
If the home was built before 1978, federal law requires the seller to disclose any known lead-based paint hazards before the buyer is locked in. The seller must provide an EPA-approved pamphlet, share any inspection reports they have, and give the buyer at least 10 days to arrange a lead inspection (the buyer can waive that window in writing). The contract itself has to include a specific lead warning statement signed by both parties, and the seller must keep the signed disclosure for at least three years after closing.2eCFR. 24 CFR Part 35 Subpart A – Disclosure of Known Lead-Based Paint and Lead-Based Paint Hazards Upon Sale or Lease of Residential Property
FIRPTA Withholding for Foreign Sellers
If the seller is a foreign person or entity, federal tax law requires the buyer to withhold 15% of the sale price and send it to the IRS.3Internal Revenue Service. FIRPTA Withholding The responsibility sits with the buyer, not the seller, which catches people off guard. There is an exception for lower-priced homes: if the buyer plans to use the property as a personal residence and the sale price is $300,000 or less, no withholding is required.4Internal Revenue Service. Exceptions From FIRPTA Withholding Domestic sellers typically sign a certification of non-foreign status at closing to confirm the rule does not apply.
Form 1099-S Reporting
Whoever closes the transaction, usually the settlement agent or title company, has to report the sale proceeds to the IRS on Form 1099-S. There is an exception for primary residences: if the seller certifies the home was their principal residence and the gain falls within the exclusion limit ($250,000 for single filers, $500,000 for married couples filing jointly), the form does not need to be filed.5Internal Revenue Service. Instructions for Form 1099-S – Proceeds From Real Estate Transactions Qualifying sellers should expect to sign that certification at closing.
Your Three-Day Closing Disclosure Window
If you are financing the purchase, your lender has to send you a Closing Disclosure at least three business days before closing.6Consumer Financial Protection Bureau. What Should I Do if I Do Not Get a Closing Disclosure Three Days Before My Mortgage Closing? The document itemizes every cost: interest rate, monthly payment, loan fees, title charges, taxes, insurance. The three-day window exists so you can compare it against the Loan Estimate you got when you applied. If numbers do not match or a new fee appeared, push back then, not at the closing table when everyone is waiting for a signature.
Certain changes restart the clock. If the lender raises your APR by more than an eighth of a percent, adds a prepayment penalty, or switches the loan product entirely, you get another three business days to review. That can delay closing, which is why lenders work hard to get the numbers right the first time.
What Closing Costs Look Like
Closing costs typically run between 3% and 6% of the purchase price for buyers. On a $400,000 home, that is $12,000 to $24,000 due on closing day in addition to your down payment.
Common buyer closing costs include:
- Loan origination fee, usually around 1% of the loan amount, charged by the lender for processing the mortgage.
- Appraisal fee, typically $300 to $450 depending on property size and location.
- Title search and title insurance, which together can run from several hundred to several thousand dollars.
- Recording fees, charged by the county to record the new deed and mortgage.
- Prepaid items, meaning upfront amounts for homeowner’s insurance, property taxes, and the mortgage interest that accrues between closing and your first payment.
Sellers have their own closing costs, the largest usually being real estate agent commissions. Many states and localities also charge transfer taxes, with rates ranging from zero in some jurisdictions to several percent of the sale price in others. The contract should say which party pays each cost, because some items are negotiable. In buyer-friendly markets, sellers sometimes agree to cover part of the buyer’s closing costs as a concession.
Property taxes, HOA dues, and utility bills are typically prorated so each party pays only for the days they owned the property. If the seller prepaid taxes through year-end and you close in June, you reimburse the seller for the remaining months. The closing agent handles the math and builds it into the final settlement figures.
The Walkthrough and Closing Day
About 24 hours before closing, the buyer conducts a final walkthrough. This is not a second inspection. The goal is narrow: confirm the home is in the condition the seller promised, verify that agreed repairs were actually completed, and make sure nothing has been damaged or removed since the last visit. If the seller agreed to replace a water heater and the old one is still sitting there, this is when you catch it.
At closing, everyone gathers (in person or through a remote notarization platform) to sign. The buyer signs the mortgage note and deed of trust, the seller signs the deed, and both parties sign the settlement statement. Federal law prohibits kickbacks and fee-splitting among settlement service providers, meaning no one involved should be collecting hidden referral payments for steering your business to a particular lender, title company, or inspector.7Office of the Law Revision Counsel. 12 U.S.C. 2607 – Prohibition Against Kickbacks and Unearned Fees
Once documents are signed and funds distributed, the closing agent submits the new deed to the county recorder’s office. Recording is what officially establishes you as the owner in the eyes of third parties, which is why it happens the same day whenever possible.
Wire Fraud Is the Biggest Money-Loss Risk
This is the part of the process where people lose the most money to criminals, and it happens more often than most buyers realize. The FBI’s Internet Crime Complaint Center reported over $173 million in real estate fraud losses in 2024, with business email compromise schemes (which frequently target closings) accounting for $2.77 billion more.8FBI Internet Crime Complaint Center. 2024 IC3 Annual Report
The scam typically works like this. A criminal hacks or spoofs the email account of a title company, agent, or attorney. They send the buyer an email that looks legitimate, complete with logos and a familiar name in the “from” field, containing wiring instructions. The money routes to the criminal’s account and is often moved overseas within hours. Unlike credit card fraud, wired money is almost never recoverable.
A few habits protect you. Before wiring any money, call the title company or closing attorney at a phone number you got independently, not from the email with the wiring instructions. Verify the account number, routing number, and bank name over the phone. Be suspicious of any last-minute change to wiring instructions, especially one arriving by email. Legitimate title companies do not suddenly switch bank accounts the day before closing. If something feels off, delay the wire until you have confirmed everything.
What Happens When Someone Breaks the Contract
If the buyer backs out without a valid contingency, the usual consequence is losing the earnest money. Most contracts include a liquidated damages clause that treats the deposit as the seller’s agreed compensation for the breach. The seller keeps the money, the deal ends, and neither side goes to court. This exists because calculating a seller’s actual losses from a failed sale is difficult and expensive to litigate.
When a seller refuses to close, the buyer’s remedies look different. Because every piece of real property is considered legally unique, a court can order the seller to go through with the sale. That remedy, called specific performance, requires the buyer to show they were ready and able to close and that money alone would not adequately compensate them. It is a powerful tool, but pursuing it means filing a lawsuit and waiting months or longer. Some contracts limit the buyer’s remedies to a refund of the deposit and reimbursement of expenses, which effectively blocks a specific performance claim. Read the remedies section carefully before signing, because it determines what you can actually do if the other side walks.
Many contracts also require written notice giving the breaching party a chance to cure the problem within a set number of days. Sending that notice is not just courtesy. Failing to send it when the contract requires can weaken your own legal position before you ever get in front of a judge.
