Bidding on a house works like this: your agent submits a written offer to the seller that spells out your price, an earnest money deposit, a proposed closing date, and the contingencies you want to keep, and the seller then accepts it, rejects it, or sends back a counter-offer until both sides sign the same set of terms. To be enforceable, the agreement has to be in writing and signed by both parties. Everything else is detail on top of that structure.
What to Have Ready Before You Bid
Sellers want to see that you can actually close before they take your offer seriously. Two documents usually do that work. A pre-approval letter from a lender, issued after review of your credit reports, tax returns, and debt-to-income ratio, states the maximum loan amount you qualify for and is generally valid for 60 to 120 days. Proof of funds, typically a recent bank or brokerage statement, shows you have the liquid cash for your down payment and closing costs.
Many sellers won’t even review an offer that arrives without these. If your financing comes from a recognized mortgage lender or financial institution, include the paperwork with the bid.
What Goes Into the Written Offer
The offer price is the headline number, but it’s not the only figure that matters. The earnest money deposit, usually 1% to 5% of the purchase price, signals that you’re serious. That money sits in a neutral escrow or trust account, not the seller’s pocket, until the deal closes or falls apart.
The offer also fixes dates. Close of escrow generally lands 20 to 60 days after the seller accepts. Possession, meaning when you actually get the keys and take physical control, usually happens at closing, but you and the seller can agree in writing to an earlier or later handoff. Pinning this down in the contract keeps arguments from surfacing later.
Contingencies That Protect You
Contingencies are conditions written into the offer that let you exit the deal, or renegotiate, if something specific goes wrong. Three are standard.
A home inspection contingency gives you a window, often 5 to 15 days, to have the property evaluated. Depending on how the clause is written, you can walk away or push for repairs if the inspection turns up serious problems. An appraisal contingency ties the deal to the property appraising at a value the lender will finance; if the appraisal comes in low, you can renegotiate the price or cancel. A financing contingency sets a deadline for final loan approval and lets you exit without losing your deposit if the lender ultimately says no despite your good-faith effort.
Making a Bid Stand Out in a Competitive Market
When multiple buyers are chasing the same house, sellers often call for highest-and-best offers by a set deadline. Response windows compress, sometimes to just a few hours, and buyers frequently raise their price or waive contingencies to stand out.
Two tools show up often in these situations. An escalation clause automatically bumps your offer above competing bids up to a ceiling you set. An appraisal-gap term commits you to covering some or all of the difference in cash if the home appraises below your offer price, which can override the protection a standard appraisal contingency would give you. Both add strength, and both add risk. Read the language carefully before signing.
Disclosures and Addenda That Ride With the Offer
Federal law requires sellers of most housing built before 1978 to provide lead-based paint disclosures, including an information pamphlet and a chance for you to conduct a lead risk assessment if you want one.
Offers also typically carry addenda that spell out specifics:
- The type of financing being used
- Timelines for professional home inspections
- Provisions tied to the sale of your current home
- Lists of personal property, such as appliances, included or excluded from the sale
- Appraisal-gap provisions for a low valuation
How the Offer Is Submitted, Countered, and Accepted
Your agent sends the drafted offer to the listing agent. Offers include an expiration date and time, usually ranging from a few hours to three days after delivery. Within that window the seller can accept, reject, or send back a written counter-offer with different terms, such as a higher price or a different closing date. A counter-offer legally rejects your original bid while proposing new terms, so you’re now the one deciding whether to accept, counter again, or walk.
The bid is generally considered accepted once both parties have signed the same document and it has been delivered to both sides. In some jurisdictions, an attorney-review period follows, during which lawyers review or draft the final contract. Once that clears, the signed agreement is a legally enforceable contract that governs the rest of the transaction.
When Your Earnest Money Is at Risk
Earnest money is generally refundable if you cancel within the timeframe of a specific contingency you kept in the contract. If you walk away for a reason the contract doesn’t cover, the seller can often claim the deposit. This is why waiving contingencies to win a competitive bid is a real trade-off, not a formality: you’re trading legal exit ramps for a stronger offer, and the deposit is what’s on the line.
The Truth in Lending Act separately requires your lender to give you clear written disclosures of loan terms and costs, including the amount financed, the finance charge, and the annual percentage rate, before you close on the mortgage.1Office of the Law Revision Counsel.
