What Is a Bona Fide Offer in Real Estate? Requirements and Proof

A bona fide offer in real estate is a written, good-faith proposal to buy a property at a specific price on specific terms, backed by enough detail and financial proof that the seller could accept it and create a binding contract. The Latin phrase means “in good faith,” and in practice it separates a serious buyer from someone kicking tires. Every enforceable purchase contract starts with one.

Why the Offer Has to Be in Writing

Real estate deals live or die on paper. Under the statute of frauds, contracts for the sale of land must be in writing and signed by the parties to be enforceable.1Legal Information Institute. Statute of Frauds A verbal promise to buy someone’s house, no matter how sincere, carries no legal weight. The writing requirement exists to prevent the “he said, she said” disputes that would otherwise plague high-value property deals.

So a bona fide offer is always a written document. It does not have to be long or complicated, but it does need to spell out enough that both sides understand what they are agreeing to. A friendly letter expressing interest is not an offer. A document with real terms is.

What Has to Be in the Offer

An offer counts as bona fide when it contains enough specificity that acceptance would create a binding contract. Requirements vary by jurisdiction, but the core pieces are consistent:

  • Property identification: the street address plus the legal description or the parcel number from county records, so there is no ambiguity about which property is changing hands.
  • Full legal names of the buyer and seller.
  • Purchase price as a definite dollar amount, not a range and not “market value.”
  • Financing terms: cash or mortgage, and if mortgage, the loan type and amount.
  • A proposed closing date.
  • An expiration date and time, after which the offer lapses automatically. Without one, your offer could sit open indefinitely while the seller shops it against other buyers.

Missing any of these weakens the offer. An offer with no purchase price is not really an offer. One with no closing date leaves the timeline entirely in the seller’s hands. The more complete the document, the harder it is for anyone to question whether it was made in good faith.

Proving You Can Actually Pay

Writing down the right numbers is necessary but not enough. Sellers want evidence that you can follow through. Two documents do most of that work.

Earnest Money

Earnest money is a deposit you put up when the contract is signed, usually 1% to 3% of the purchase price. It goes into escrow with a neutral third party and stays there until closing. If you walk away for a reason the contract does not permit, the seller can keep it as compensation for taking the property off the market. If you walk away for a reason the contract does allow, such as a failed inspection or a low appraisal, you get it back.

The amount signals commitment. In competitive markets, buyers sometimes offer more than 3% to stand out. In slower markets, 1% is common. There is no legally required minimum in most places, but offering none at all tells the seller you are not particularly committed.

Pre-Approval or Proof of Funds

If you are financing, a pre-approval letter from a lender carries real weight. The Consumer Financial Protection Bureau notes that pre-qualification and pre-approval letters both indicate a lender’s general willingness to lend up to a certain amount, but the terms are not standardized. Some lenders issue pre-qualification based on unverified information you report, and reserve pre-approval for letters backed by verified documents.2Consumer Financial Protection Bureau. What’s the Difference Between a Prequalification Letter and a Preapproval Letter From the seller’s side, the letter backed by actual document review is the one that matters. Ask your lender which process they use and what the letter represents before attaching it.

If you are paying cash, the equivalent is a proof-of-funds letter from your bank on institution letterhead, showing enough liquid assets to cover the purchase price. Banks can usually produce one within a day or two. A recent account statement helps too, though it is wise to redact your account number before handing it to a stranger.

How Contingencies Fit In

Contingencies are conditions built into the offer that must be met before the sale becomes final. If one is not satisfied, you can withdraw and recover your earnest money. The common ones:

  • Financing contingency: the deal depends on your mortgage actually coming through. If the lender declines, you are not locked in.
  • Inspection contingency: you have the right to hire a professional inspector, and if serious problems turn up, you can renegotiate or walk.
  • Appraisal contingency: the property has to appraise at or above the purchase price. If it comes in lower, you can renegotiate or exit without penalty.

Standard contingencies do not make an offer any less bona fide. Sellers expect to see them. The suspicion comes when an offer is loaded with unusual conditions, like making the sale depend on the buyer first selling an unrelated property or receiving an inheritance. Sellers tend to read those as escape hatches, and the question of commitment becomes fair.

What Happens After You Submit

Submitting a bona fide offer does not guarantee a deal. The seller has three options: accept it as written, reject it, or counter. The counter matters legally, because it changes the landscape.

When a seller counters, your original offer dies. The counter is a new offer from the seller to you, and you are under no obligation to take it. You can accept, reject, or counter back with your own modifications. This can go through several rounds, and each counter kills the one before it. Reject the seller’s counter and you cannot later circle back and accept your original terms unless the seller agrees.

This is why the expiration deadline matters. If your offer gives the seller 48 hours and they counter at hour 47, the clock resets on their new offer. Without a deadline, a seller could sit on your paperwork for weeks while using it as leverage with other buyers. An offer that stays open forever is generous to the seller and risky for you.

What a Non-Bona-Fide Offer Looks Like

Some offers look legitimate on paper but are not made in good faith. The patterns experienced agents and sellers watch for:

  • Verbal-only proposals. If someone says they want to buy and never follows up in writing, that is not an offer under any legal framework. It creates no obligation on either side.1Legal Information Institute. Statute of Frauds
  • Deliberately incomplete terms. Missing the purchase price or closing date is not an oversight. It is either a placeholder meant to tie up the property while the buyer weighs options, or it is from someone not serious enough to fill in the blanks.
  • Offers meant to stall. Some buyers submit offers with no real intention of closing, hoping to take the property off the market and keep competing buyers out. Sellers who accept these often lose weeks of exposure.
  • No financial documentation. An offer without earnest money, without a pre-approval letter, and without proof of funds asks the seller to take everything on faith. That is the opposite of bona fide.

One more boundary worth naming. A straw purchase, where someone with clean credit signs the paperwork while a hidden buyer stays in the background, is not a shady deal in a gray area. It is a federal crime. False statements on a mortgage application to disguise the true buyer can draw a fine of up to $1,000,000, up to 30 years in prison, or both.3Office of the Law Revision Counsel. 18 USC 1014 – Loan and Credit Applications Generally A separate bank fraud statute carries the same maximum penalties for schemes to defraud a financial institution through false representations.4Office of the Law Revision Counsel. 18 USC 1344 – Bank Fraud Even if the loan is repaid in full, the act remains illegal, because the lender was exposed to risks it never agreed to take on.

Put the pieces together and the standard is straightforward. A bona fide offer is written, specific, time-bound, and backed by evidence that you can do what you are proposing to do. Everything else is talk.
