To make an offer on a house, you deliver a written proposal to the seller through their agent that sets your price, your earnest money deposit, the contingencies you need, and the dates you want to close and take possession. If the seller signs it as written, that proposal becomes a binding purchase contract. Everything you include or leave out shapes your rights for the rest of the deal, so the offer stage is where most of the real legal work happens.
Prove You Can Pay Before You Write Anything
Sellers routinely ignore offers that arrive without financial documentation, whatever the price on the front page. If you’re financing, that means a pre-qualification or pre-approval letter from a lender. If you’re paying cash, it means a proof of funds letter from your bank.
The Consumer Financial Protection Bureau notes that lenders use “pre-qualification” and “pre-approval” inconsistently, so what actually matters is whether the lender verified your income, assets, and credit before issuing the letter.1Consumer Financial Protection Bureau. What’s the Difference Between a Prequalification Letter and a Preapproval Letter A verified letter carries more weight with sellers because it signals the loan is more likely to close. Neither type is a guaranteed loan commitment.
For cash offers, the proof of funds letter must show liquid assets. Retirement accounts, bonds, and life insurance policies that aren’t readily accessible generally don’t count. Most banks can produce the letter within a week.
What Goes Into the Offer
The offer is a set of terms you’re proposing. None of it is boilerplate, and each field changes your legal position if the seller signs.
Purchase Price and Earnest Money
Set your price against comparable sales, the condition of the home, and how competitive the market is. Alongside the price, you commit an earnest money deposit as a good-faith payment. The National Association of Realtors suggests buyers expect to put down between one and three percent of the purchase price, with deposits as high as ten percent in competitive situations.2National Paralegal College. Putting Your Money Where Your Mouth Is: Deposits and Real Estate Contracts
The deposit is held by a neutral third party, usually a title company, escrow agent, or attorney, and applied to your down payment and closing costs at closing.3National Association of Realtors. Consumer Guide: Escrow and Earnest Money If the deal collapses under a contingency, you get it back. If you walk away without a contractual reason, the seller may be entitled to keep it as damages.
Closing Date and Possession
Your offer proposes a closing date, the day funds and title change hands. The average time to close a purchase mortgage is roughly 42 to 43 days, so most offers target a 30 to 60 day window.4Freddie Mac. Closing Your Loan Cash deals can close much faster.
Possession and closing aren’t always the same day. If the seller needs extra time to move out, a post-closing occupancy arrangement lets them stay for a set period, sometimes paying rent. If you need in before closing, a pre-closing occupancy agreement handles the reverse. Either way, spell out the length, any rental payment, and who carries insurance in a written addendum rather than a handshake.
Personal Property
Anything attached to the house, such as built-in shelving or a furnace, generally transfers with the property. Anything not permanently attached is up for argument. If you want the refrigerator, washer and dryer, window treatments, or a mounted TV, name each one in the offer. Vague language here causes more closing-table fights than almost anything else.
Contingencies That Let You Walk Away
Contingencies are conditions that must be met before the sale moves forward. Think of them as contractual exit ramps: if a contingency isn’t satisfied, you can typically withdraw and get your earnest money back. Leave them out and you’re buying the house regardless of what surfaces before closing.
Financing Contingency
A financing contingency gives you a set number of days to secure a mortgage. If your loan falls through for a qualifying reason inside that window, you can back out without penalty.5My Home by Freddie Mac. Understanding Contingency Clauses in Homebuying This matters even with a pre-approval, because lenders can still deny final approval if your employment changes, new debt appears on your credit report, or the property itself doesn’t meet their requirements.
Inspection Contingency
The inspection contingency gives you a window, typically seven to ten days after acceptance, to hire a professional inspector and evaluate the home’s structure, roof, plumbing, electrical systems, and foundation. If problems surface, you can negotiate repairs, request a price reduction, or walk. Waiving inspection means buying as-is. A cracked foundation or failed electrical panel easily costs five figures.
Appraisal Contingency
Your lender orders an independent appraisal to confirm the home is worth what you agreed to pay. If it comes in low, an appraisal contingency lets you walk away, renegotiate to the appraised value, or pay the gap out of pocket. Without it, you’re on the hook for the difference, because lenders won’t raise their loan amount just because you offered more than the home appraised for.
Title Contingency
A title search uncovers whether the seller actually has clear ownership. Outstanding liens, boundary disputes, unpaid taxes, or easements can cloud a title. A title contingency lets you exit if problems surface that the seller can’t or won’t fix. Most buyers include this and most lenders require it.
Home Sale Contingency
If you need to sell your current home to afford the new one, a home sale contingency makes your offer conditional on that sale closing. It protects you from owning two properties at once, but sellers dislike it because it adds uncertainty. In a competitive market, offers with home sale contingencies are usually the first rejected.
Get the Paperwork Right
Real estate contracts must be in writing to be enforceable. The requirement comes from the Statute of Frauds, adopted in every state, which blocks enforcement of verbal agreements involving land.6Legal Information Institute (LII) / Cornell Law School. Statute of Frauds A verbal promise about price, closing date, or any other term cannot force a sale.
Most offers use a standardized Residential Purchase Agreement form from a real estate agent or attorney, with blank fields for price, dates, and party names, plus required disclosures. Fill it in precisely. Clerical errors in names, legal descriptions, or dollar amounts can delay or void the offer. Special terms like an escalation clause or a post-closing occupancy agreement get attached as separate addenda.
For homes built before 1978, federal law requires a lead-based paint disclosure addendum. Sellers must provide a Lead Warning Statement and give you a ten-day window to conduct a paint inspection or risk assessment for lead hazards.7US EPA. Real Estate Disclosures about Potential Lead Hazards Most states also require sellers to disclose known material defects such as structural problems, water damage, or pest infestations, though the specifics vary.
Electronic signatures are legally valid for purchase agreements under the federal Electronic Signatures in Global and National Commerce Act.8National Credit Union Administration. Electronic Signatures in Global and National Commerce Act (E-Sign Act) Most agents use digital signature platforms that time-stamp each signature.
Submitting the Offer and Setting an Expiration
Your agent delivers the completed package to the seller’s listing agent, usually through a digital signature platform or an encrypted PDF. Confirm delivery. Incomplete packages and spam filters cost buyers their own deadlines. Your agent should get an acknowledgment that everything arrived, including addenda and your pre-approval or proof of funds letter.
Most offers include an expiration window, typically 24 to 72 hours, after which the offer dies if the seller hasn’t responded. That deadline keeps you from being locked into a proposal while the seller shops it for better numbers.
What the Seller Can Do With Your Offer
Accept
If the seller signs the offer exactly as written, you have a binding contract. Both sides now have legal obligations, and backing out without a contingency exposes you to breach. Your earnest money goes into escrow and the contingency timelines start running.
Reject
A flat rejection ends the negotiation. Rejections are usually delivered in writing, but a seller can also simply let the offer expire, which has the same effect.
Counter
The most common outcome is a counteroffer, where the seller changes one or more terms: a higher price, a different closing date, the removal of a contingency. Under basic contract law, a counteroffer is a rejection of your original offer and a new proposal in its place. Your original terms no longer exist. You can accept, reject, or counter back. The back-and-forth continues through the agents until both sides agree or one walks.
Backup Offer
If the seller already has an accepted offer from another buyer, you can submit a backup offer that puts you next in line if the primary deal fails. The tradeoff is that a backup ties your hands. You’re on hold, unable to freely pursue other homes while you wait to see whether the primary contract collapses.
Making Your Offer Stand Out
In a multiple-offer situation, the highest price doesn’t automatically win. Sellers weigh the full package: certainty of closing, timeline flexibility, and how few complications they expect. A few moves that consistently help:
- Raise your earnest money to three to five percent, which signals stronger commitment than the standard one to two percent.
- Ask the listing agent for the seller’s preferred closing date before writing the offer, and match it.
- Shorten the inspection window to five days, or limit repair requests to health, safety, and structural issues, instead of waiving inspection outright.
- Add appraisal gap coverage, meaning you’ll pay a specific dollar amount above the appraised value out of pocket.
- Drop weaker contingencies you don’t actually need, such as a home sale contingency if you don’t have a house to sell.
Waiving contingencies entirely is the most aggressive move and the riskiest. Waive financing and a loan denial can cost you the earnest money and expose you to a breach claim. Waive inspection and any post-closing repairs are yours. Only waive what you can afford to lose.
Escalation Clauses
When you expect multiple offers, an escalation clause automates your bidding. You state your initial price, the increment you’ll go above any competing offer, and the absolute cap. For example, $300,000 with a $2,000 increment up to a cap of $310,000: if another buyer offers $305,000, your offer automatically rises to $307,000. The catch is that the clause tells the seller your ceiling. Pair any escalation clause with an appraisal contingency so you don’t end up obligated above the home’s appraised value.
Attorney Review States Are Different
A handful of states, including New Jersey and Illinois, build an attorney review period into the contract. In New Jersey, each side gets three business days after signing to have an attorney review and request changes or cancel outright. In Illinois, the period is five business days. During attorney review, either side can void the contract without penalty, even after both signed. If you’re buying in one of these states, a signed offer isn’t truly final until the review period expires. Your agent will know whether your state uses one.
The offer is where the deal starts, and the terms you put into it decide what happens if anything goes wrong. Keep a calendar of every date once your offer is accepted, and expect your agent to be tracking the same dates independently. Missed deadlines are the most common way a signed deal quietly falls apart.
