The importance of back-up offers and why you should consider writing one.

Writing Backup Offers

The Backup Offer: Why Losing the House Doesn’t Have to Be the End of It.

When inventory is tight and multiple buyers are circling the same listing, competing offers are routine. So is the outcome nobody prepares for: you write a strong offer on the right house, another buyer beats you on price or terms, and you go back to searching.

That is the moment most buyers give up on the property. It is also the moment a good agent does the opposite and writes a backup offer.

What a backup offer actually is

A backup offer is a secondary contract on a home that is already under contract with another buyer. It sits in reserve. If the primary contract terminates for any reason, you move from second position into first — without competing all over again, and without the seller returning the property to the open market.

On a desirable listing, several buyers may be holding backup positions. Order matters. Submitting first can mean being first in line the moment the primary deal comes apart.

The strategic value is easy to underestimate, because it depends on a number most buyers have never seen.

Contracts fail more often than people think. A signed contract is not a closed sale.

Nationally, roughly 13.4% of homes that went under contract in April 2026 had their agreements cancelled — about one in seven — a level that has held within half a percentage point for the past year and a half (Redfin). Cancellation rates vary widely by market: Atlanta ran 19.3% in the same month, while San Francisco came in at 2.8% (Redfin).

The National Association of REALTORS® measures this differently, surveying agents about their most recent transaction, and reports a lower termination figure — around 5% to 6% in recent months, alongside about 14% of contracts experiencing delayed settlements (NAR REALTORS® Confidence Index). Both measures point the same direction even though they count differently. NAR has consistently identified the same three culprits behind dead and stalled deals: home inspections, buyer financing, and appraisals (NAR).

Put plainly: on any given listing, there is a meaningful probability the winning buyer never closes. A backup offer is simply the discipline of positioning yourself for that probability instead of hoping to stumble onto it.

The four ways a primary contract comes apart

Understanding why deals die is what allows you to write a backup offer that looks better than the one ahead of you.

1. Inspection contingencies

The buyer typically has 10 to 14 days to investigate the property’s condition. Within that window they may order a general home inspection plus any combination of sewer or septic, roof, structural, HVAC, and termite inspections.

This is the most common failure point, and not always because the findings are catastrophic. Deals die here when the parties cannot agree on who absorbs the cost of what was found. If repairs or credits cannot be negotiated, the buyer terminates.

2. Financing contingencies

Unless a buyer is paying cash, the offer is contingent on financing — and financing is the contingency buyers have the most control over.

Get fully pre-approved before you tour a single house. Not pre-qualified. Pre-approved, with a letter, from a local lender who knows this market and can be reached by a listing agent on a Sunday afternoon. If your agent has not connected you with a qualified local lender before showing you homes, that is a meaningful signal about how they will represent you when it counts.

The reason to front-load this is simple: loan approval typically takes around three weeks, and there are more ways to be denied than most buyers realize. You want to discover a problem in your file while you are still looking, not while you are under contract.

Once your application is in, protect it. Do not make a large purchase — a car, a boat, furniture on credit. Do not change jobs. Do not move money between accounts without telling your loan officer. If you lose your job, the purchase pauses until you are employed again. Underwriters re-verify late in the process, and any of these can unwind an approval that was already issued.

3. Appraisal contingencies

When a lender is involved, an appraisal is required. If the home appraises below the contract price, the deal has a gap problem, because the lender will only finance against the appraised value.

Three outcomes: the seller reduces to the appraised value, the buyer covers the difference in cash, or the contract terminates. In competitive markets where buyers have bid aggressively above list, this is a frequent point of collapse — and NAR’s tracking shows appraisal issues behind a persistent share of delayed settlements each month (NAR REALTORS® Confidence Index).

4. Buyer’s remorse

The least technical and most common reason of all. The offer was made quickly under competitive pressure, and once the buyer has time to think, the math or the fit stops working. The renovation budget does not exist. The commute is worse than it looked. A better house comes on the market a week later.

Sometimes buyers simply walk, forfeit the earnest money, and move on. Redfin attributes much of the current elevated cancellation rate to exactly this — buyers getting cold feet as costs stay high.

How to write a backup offer worth accepting

A backup offer is not a lowball placeholder. It only works if the seller would genuinely rather have you than return to market.

• Come in at or near asking price. You are competing against a contract the seller already agreed to. Anything materially below it gives them no reason to hold your position.

• Include the pre-approval letter. In second position, your credibility is the entire product you are selling.

• Keep your contingencies clean. Reasonable inspection window, no home-sale contingency if you can avoid it, realistic closing timeline.

• Get it in writing and get it acknowledged. A verbal “let us know if it falls through” is not a backup offer. It should be a signed contract with clear language on when second position converts to first.

• Understand your own exit. Know the terms under which you may withdraw, so you are not indefinitely tied to a property while the primary buyer takes their time.

Why this matters right now

Backup offers are usually framed as a tight-market tactic, and in a bidding war they absolutely are. But the current environment makes the case even more directly: cancellations have been running near record highs for this point in the calendar (Redfin). More contracts falling apart means more second positions converting.

Losing a house you wanted is not always final. Frequently it is a timing problem rather than an outcome — and the buyers who understand that are the ones holding a signed contract when the first deal unravels.

One practical note: ask your agent to calendar a check-in on the property two weeks after the primary contract is signed. That is roughly when the inspection period closes, and it is the single most likely window for the deal ahead of you to come apart.
