An offer letter for a house is the written proposal you give a seller stating the price you’ll pay, the conditions that have to be met, and the timeline you want to close on. Your agent usually prepares it on a standard purchase agreement form used in your state. Once the seller signs it without changes, that offer becomes a binding purchase contract, and both sides are legally committed to the terms inside it.
What Has to Be in the Offer
Most buyers don’t draft the document from scratch. Your agent pulls the standardized purchase agreement used in your area, and you fill in the key blanks together. The form handles the legal boilerplate; the terms that matter are the ones you set.
At a minimum, every offer includes:
- The property address
- The names of all buyers who will be on the title
- Your proposed purchase price
- The amount of your earnest money deposit
- Your planned down payment
- A target closing date
Earnest money is the cash you put up front to show the seller you’re serious. In most markets it runs between 1% and 3% of the purchase price, though competitive or high-cost areas push that higher. The money sits in an escrow account managed by a third party and is credited toward your purchase at closing. The size of the deposit is strategic. A larger one signals financial commitment; a smaller one preserves your liquidity.
Your offer should also spell out any personal property you expect to come with the house. If you want the refrigerator, the washer and dryer, or the mounted TV to stay, name those items explicitly. Sellers aren’t obligated to leave anything that isn’t permanently attached to the property, and assumptions about what “comes with the house” cause more closing-table arguments than you’d expect.
Documents You Attach to Prove You Can Pay
The offer itself tells the seller what you want to pay. The attachments tell them whether you actually can, and sellers look at the attachments before much else. A high offer from a buyer who can’t close is worse than a lower offer from one who can.
If you’re financing, include a mortgage pre-approval letter from your lender. This confirms the lender has reviewed your income, credit, and debts and is willing to extend a loan up to a stated amount. A pre-approval carries more weight than a pre-qualification, which is typically just a preliminary estimate without verification. The letter should be recent, and the approved amount should cover your offer price.
If you’re paying cash, you need proof of funds instead. That’s usually a bank or investment account statement, or a letter from your financial institution confirming you have enough liquid assets to cover the full purchase price. Most sellers won’t take the home off the market for a cash buyer who hasn’t proven the cash exists.
Contingencies That Let You Walk Away
Contingencies are the conditions written into your offer that let you exit the deal and recover your earnest money if specific things don’t work out. They’re your safety net. Understanding each one is where buyers either protect themselves or leave money on the table.
Financing Contingency
A financing contingency gives you a set number of days to secure your mortgage. If your loan falls through despite a good-faith effort, this clause lets you exit the contract and get your deposit back. It typically specifies the loan amount, the type of mortgage, and sometimes a maximum interest rate. Buyers in volatile rate environments sometimes include a rate ceiling to protect against sudden spikes during the loan approval window.1FHFA. FHFA Announces Conforming Loan Limit Values for 2026
Inspection Contingency
The inspection contingency gives you a window, usually 7 to 10 days, to hire a professional inspector to evaluate the property. A standard home inspection typically costs between $300 and $500, with larger homes or specialized testing for things like radon or sewer lines running higher. If the inspector finds significant problems, you can negotiate repairs, ask for a price reduction, or cancel the contract. Without this contingency, you’re buying as-is, and whatever the walls are hiding becomes your problem.
Appraisal Contingency
When you’re using a mortgage, your lender will order an independent appraisal to confirm the home is worth at least what you’re paying. If it appraises low, the lender won’t finance the full amount, and you’d need to cover the gap in cash or renegotiate the price. An appraisal contingency, which usually runs 10 to 14 days, gives you the right to back out or renegotiate if the home doesn’t appraise at the contract price.
Title Contingency
A title contingency requires confirmation that the seller actually has clear legal ownership and the right to sell. During this window, a title company searches public records for outstanding liens, boundary disputes, ownership gaps, or other problems that would prevent a clean transfer. If an issue surfaces that can’t be resolved, this contingency lets you walk away. Title problems are relatively rare, but when they occur they can completely derail a purchase.
Home Sale Contingency
If you need to sell your current home before you can afford to buy the new one, a home sale contingency makes your offer conditional on that sale closing. This is the contingency sellers like least, because it chains their timeline to a transaction they don’t control. To balance the risk, sellers often negotiate a kick-out clause. They continue marketing the property, and if a better offer arrives, you get a short window (often 48 to 72 hours) to either drop the contingency and commit, or step aside for the new buyer.
How the Offer Gets Delivered
Your agent handles delivery. In most transactions the completed offer is transmitted electronically through a platform like DocuSign or Dotloop to the seller’s listing agent. Federal law gives electronic signatures the same legal standing as ink on paper, so clicking “sign” on your laptop is as binding as sitting at a table with a pen.2Office of the Law Revision Counsel. 15 US Code 7001 – General Rule of Validity
Every state requires real estate contracts to be in writing to be enforceable, a legal principle known as the Statute of Frauds. A verbal agreement to buy a house, no matter how specific, is not a contract. Until the terms are on paper (or its digital equivalent) and signed, neither side has any legal obligation.
Your offer should include an expiration deadline, typically 24 to 48 hours after delivery. Without one, your offer technically stays open indefinitely, which means you could stay locked into terms you’ve mentally moved on from while the seller shops for something better.
Attorney Review in Some States
In a handful of states, contracts include a mandatory attorney review period, usually three to five business days, during which either party’s lawyer can modify or cancel the agreement. If you’re buying in one of those states, the contract isn’t truly final until the review period expires without objection. Your agent will know whether yours requires this step. Ask early, because the review period effectively delays the start of your contingency timelines.
What the Seller Can Do With Your Offer
Once the seller has your offer, three things can happen. Only one of them creates a deal.
Full acceptance. The seller signs the offer exactly as you wrote it, and the document becomes a ratified contract. Both sides are now legally bound by every term in it. This is most common when the offer is at or near asking price with clean terms.
Counter-offer. The seller wants to change something. Maybe a higher price, a different closing date, or fewer contingencies. Legally, a counter-offer is a rejection of your original proposal combined with a new one. You can accept it, reject it, or counter back. This can go several rounds, and nothing is binding until both parties sign the same version. Each counter should carry its own expiration.
Rejection. The seller owes you no explanation, and neither side has any further obligation. If you still want the property, you’d need to submit a new offer. In hot markets, sellers sometimes reject without countering because they already have a better bid.
What You Stand to Lose If You Back Out
Once your offer is accepted, you’ll deposit your earnest money into escrow, usually within a few business days. The money sits with a neutral third party, typically a title company or escrow agent, until closing.
If you back out for a reason covered by one of your contingencies, you get the deposit back. Failed inspection, denied mortgage, low appraisal: these are exactly the scenarios contingencies exist to cover. If you simply change your mind or miss a contingency deadline, the seller is usually entitled to keep your deposit as compensation for taking the house off the market.
Many purchase agreements include a liquidated damages clause that limits the seller’s remedy to the earnest money. If you breach the contract, the seller keeps the deposit but can’t sue you for more. Not every contract includes this provision. Without it, a seller could theoretically pursue a lawsuit seeking the difference between your contract price and whatever they eventually sell for. In practice most residential disputes end at the earnest money, but reading your contract’s default provisions before you sign is the kind of tedious step that occasionally saves tens of thousands of dollars.
Mutual Rescission
Sometimes both sides realize the deal isn’t going to work. A mutual rescission is a written agreement to cancel the contract and return the earnest money to the buyer. Both parties must sign it. This often comes up when an inspection reveals expensive problems and neither side wants to negotiate further, or when a life event disrupts the timeline. Once signed, neither side has any remaining obligations under the original contract.
Making an Offer Stand Out in a Bidding War
When a seller is reviewing several offers at once, price alone doesn’t always win. The terms around the price can matter just as much.
Escalation Clauses
An escalation clause automatically raises your offer in set increments above any competing bid, up to a maximum ceiling you define. For example, you might offer $400,000 with an escalation clause that adds $2,000 above any competing offer, capped at $425,000. If the highest competing bid is $410,000, your offer automatically becomes $412,000. The ceiling is critical. It’s the absolute most you’re willing to pay, and the clause won’t push you past it. Smart buyers also require the seller to show proof of the competing offer that triggered the escalation, to prevent manipulation.
Appraisal Gap Coverage
In a bidding war, the purchase price can climb above what an appraiser will later determine the home is worth. An appraisal gap clause is your promise to cover the difference between the appraised value and the contract price, up to a specific dollar amount, in cash at closing. For a seller weighing multiple bids, an offer with gap coverage is often more attractive than a slightly higher bid without it, because it removes the biggest risk of a deal collapsing over a low appraisal. If the gap exceeds your committed amount, you typically retain the right to renegotiate or cancel.
Waiving Contingencies
Some buyers try to make their offer more competitive by waiving contingencies entirely. Dropping the inspection contingency means you won’t ask for repairs. Dropping the appraisal contingency means you’ll pay the contract price regardless of what the appraiser says. These moves make offers more attractive to sellers, but they strip out your safety net. Waiving the inspection on a property you haven’t thoroughly evaluated works out until it doesn’t, and when it doesn’t, you’re looking at repair bills with no recourse. If you waive, do it selectively, and know exactly what protection you’re giving up.
Why Not to Attach a Personal Letter
You may have heard that writing a heartfelt letter to the seller, sometimes called a “love letter,” can help your offer stand out. The idea is that telling sellers about your family, your story, or your connection to the neighborhood makes them emotionally invested in choosing you. The problem is that these letters routinely reveal information about protected characteristics, and that creates fair housing liability for the seller.
Federal law prohibits refusing to sell or discriminating in the terms of a sale because of a buyer’s race, color, religion, sex, familial status, national origin, or disability.3Office of the Law Revision Counsel. 42 US Code 3604 – Discrimination in the Sale or Rental of Housing A letter describing your family celebrating holidays, mentioning your church, or including a family photo makes it nearly impossible for a seller to prove their decision wasn’t influenced by that information. Even without bad intent, the letter creates a paper trail that looks exactly like the evidence a discrimination claim would need.
The National Association of Realtors discourages the practice, and many listing agents refuse to deliver these letters to their clients. The safest approach is to let your offer terms speak for themselves. A strong price with solid financing beats a personal story, and it doesn’t expose anyone to a fair housing complaint.
After the Offer Is Accepted
Once both sides have signed the same version, the transaction enters escrow. Your earnest money gets deposited, your contingency clocks start running, and a title company begins preparing for the ownership transfer. The signed offer, now a ratified purchase agreement, is the governing document for every step that follows, from inspection through final walk-through to the moment you get the keys.
Between acceptance and closing, expect to stay busy. You’ll schedule the home inspection, work with your lender to finalize the mortgage, review the title report, and secure homeowner’s insurance. Missing a deadline in the contract can cost you your contingency protections, so track every date carefully. Your agent should be managing the timeline, but it’s your money and your name on the contract.
