Signing a letter of intent (LOI) feels like the finish line. It isn't. An LOI is typically non-binding on price and most commercial terms, which means either side can still walk away before closing — and understanding why business sales fall through helps sellers spot warning signs early enough to address them, rather than discovering the deal is dead after weeks of work.

There's no way to make a deal collapse-proof. But most of the common causes are foreseeable, and several are within a seller's control to reduce.

The Most Common Reasons Deals Fall Through

ReasonWhat It Typically Looks Like
Buyer financing falls throughLoan approval conditions in the purchase agreement aren't satisfied, or the buyer's lender pulls back after diligence
Due diligence uncovers a problemFinancial discrepancies, undisclosed liabilities, or contract issues surface once the buyer looks closely
Valuation gap reopensThe buyer tries to renegotiate price downward based on diligence findings or market conditions
Third-party consent issuesA landlord withholds or delays consent to assign the lease, or a key contract requires approval that isn't forthcoming
Seller has second thoughtsThe seller becomes uncomfortable with the transition, the price, or the terms as closing approaches
Key employee or customer risk emergesA critical employee signals they'll leave, or a major customer relationship looks less stable than represented

Financing Gaps Are Often the Most Preventable

A buyer's financing condition is a routine part of most purchase agreements, but it's also one of the more common reasons a deal stalls or collapses — particularly if the buyer's financing wasn't well advanced before the LOI was signed. Sellers can reduce this risk by asking direct questions about financing status early, before investing heavily in exclusivity, and by having their lawyer negotiate a reasonable timeline for the buyer to satisfy financing conditions rather than leaving it open-ended.

Diligence Findings That Can Kill a Deal

Due diligence exists precisely to surface issues before closing, and it's not unusual for it to find something. What often determines whether a deal survives is how the issue is handled once it's found:

A seller who is transparent about known issues from the outset — rather than letting the buyer discover them during diligence — generally preserves more trust and negotiating room than one who doesn't.

Reducing the Risk From the Seller's Side

Frequently asked questions

Can I recover costs if a buyer walks away after signing an LOI?

It depends on what the LOI actually says. Because most LOI terms aren't binding, cost recovery usually depends on specific binding provisions — such as a break fee or cost-sharing clause — that were negotiated into the document itself.

Is it normal for price to be renegotiated after diligence?

It happens fairly often when diligence uncovers something material, though it isn't automatic or guaranteed. A seller who has disclosed known issues upfront is generally in a stronger position to resist an aggressive renegotiation.

What if I get cold feet as a seller?

It's worth discussing openly with your lawyer and, if involved, your broker, rather than trying to slow-walk the deal informally — an LOI's binding provisions, such as exclusivity, may still apply even if you're having second thoughts about proceeding.

Does a deal falling through mean something was wrong with my business?

Not necessarily. Deals collapse for reasons ranging from buyer financing to unrelated buyer circumstances, and a failed attempt doesn't automatically reflect on the underlying business — though it's worth reviewing what happened before relisting.
