Why Do House Sales Fall Through?
No Fees, No Obligation, Cash Offer.
Around one in three house sales fall through before completion. The most common reasons are broken chains, mortgage refusals or down-valuations, problems uncovered in the survey, buyers getting cold feet, and slow conveyancing. A cash sale removes almost all of these risks, because there’s no chain and no mortgage to fall apart.
The most common reasons sales collapse
- A broken chain. If any buyer or seller in the chain pulls out, the whole chain can collapse – the single biggest cause.
- Mortgage refused or a down-valuation. The buyer’s lender declines, or values the property below the agreed price, and the deal falls apart.
- Survey problems. A survey flags structural issues, damp or subsidence, and the buyer renegotiates or walks away.
- Cold feet or changed circumstances. A job move, relationship change or simple change of mind.
- Gazumping and gazundering. A higher offer tempts the seller, or the buyer drops their offer at the last minute.
- Slow conveyancing. Long delays give doubts time to grow and chains time to break.
How to reduce the risk
- Sell to a buyer who isn’t in a chain and doesn’t need a mortgage.
- Be upfront about the property’s condition so nothing derails the survey.
- Use a proactive solicitor and keep the process moving.
The certain alternative
Selling to a genuine cash buyer removes nearly every one of these risks at once: no chain, no mortgage lender, and a price held to completion. It’s the difference between a hoped-for sale and a guaranteed one. See how we break broken chains, or compare the routes in our cash buyer vs estate agent vs auction guide.
