Should I accept a cash buyer or one with a mortgage?

Two offers on the table, one cash and one with a mortgage, and the mortgaged one is a little higher. It is one of the better problems to have when selling, but it still keeps sellers up at night. The good news is there is a clear way to weigh them.

Is a cash buyer always the safer choice?

Usually, but not automatically. A cash buyer is someone buying without a mortgage, using money they already hold. Because there is no lender involved, two of the most common reasons a sale collapses simply cannot happen: the mortgage being declined, and the lender down-valuing your home.

That certainty is why cash buyers have grown. Hamptons found cash buyers made up about 35% of purchases across Great Britain in 2026, up from 30% a year earlier, as higher borrowing costs pushed more people to buy outright. Cash buyers often offer slightly below asking, and the discount is really the price of certainty.

How do I check a buyer really has the cash?

You ask for proof of funds. Proof of funds is written evidence, such as a recent bank or investment statement, that a buyer holds the money they say they have. A buyer who calls themselves cash but actually needs to sell their own home first is not a cash buyer; they are a buyer in a chain, with all the same risks.

When is a mortgaged buyer the better bet?

A mortgaged buyer is not a weak buyer. A mortgage in principle is a lender's early indication of what it might lend, not a firm offer, but a buyer with a large deposit, a mortgage offer already in hand, and no chain can be every bit as safe as a cash buyer, and they may be paying more.

The size of the gap matters too. If the mortgaged offer is meaningfully higher, that extra money can be worth a few more weeks and a little more risk, especially if their finances are strong. Certainty is valuable, but it is not the only thing on the table.

How do I decide between a safe offer and a bigger one?

1. 1. Ask both buyers for proof in writing

   Get a bank or investment statement from the cash buyer and a mortgage in principle plus deposit evidence from the mortgaged buyer. No proof, no serious consideration.

2. 2. Check what cash really means

   Confirm the cash buyer is not relying on selling their own property first. If they are, treat them as a chain buyer, not a cash buyer.

3. 3. Compare on certainty, not just price

   Weigh the size of each offer against how likely it is to actually complete. A slightly lower offer that completes beats a higher one that collapses.

4. 4. Look at each buyer's chain

   A chain-free buyer of either type is safer than one waiting on their own sale. Ask both how many links sit behind them.

5. 5. Weigh the money against the risk

   Decide what the extra pounds from the higher offer are worth to you against the added chance of delay or a fall-through.

6. 6. Keep the runner-up warm

   Ask your agent to stay in touch with the buyer you did not pick, so you have a fast fallback if your chosen sale wobbles.

Whichever you lean towards, read the buyer by what they have put in place, not by what they promise. The strongest signal is money and paperwork already committed: proof of funds seen, a mortgage offer issued, a solicitor instructed. Hold off on your own big spends and on coming fully off the market until you have seen that proof.

A cash buyer is only cash if the money is already in their account. Always ask to see it.
