My buyer wants money off because mortgage rates rose

This is a negotiation, not a verdict on your home. A buyer who has found the money more expensive has a real problem, and some of them are asking sellers to share it. Your job is to find out whether the problem is real before you decide whether to pay for it.

Why are buyers asking for money off because of rates?

Mortgage costs moved a long way in 2026. The Bank of England has held the base rate at 3.75% since December 2025, but lender pricing has moved independently of it, driven by the war in Iran and by what markets expect to happen next. At the July 2026 meeting six members of the Monetary Policy Committee voted to hold and three voted to raise, which tells you how unsettled the picture is.

The practical effect for a buyer is a higher monthly payment on the same house. Zoopla put the increase at around £125 a month on the average mortgage once rates reached 5% in April 2026, and around £232 a month for a first-time buyer in London. A buyer whose budget was already tight can genuinely be short.

Have mortgage rates actually gone up since my buyer offered?

Often, no. This is the single most useful thing to check, and almost nobody does it.

Rates did not climb in a straight line through 2026. They spiked in the spring and have come back down since, so the answer depends entirely on the date your buyer got their quote.

A buyer who agreed to buy your home in April and is asking for a reduction in August is asking you to compensate them for a rate that has fallen. That is worth knowing before you reach for your calculator.

What is normal here and what is a red flag?

What should I do when a buyer asks for a reduction on rates?

1. 1. Ask for the date and the figures in writing

   Ask your agent to get the request in writing, with the date of the mortgage quote the original offer was based on and the rate they have now been offered. A buyer with a genuine problem will provide this without complaint.

2. 2. Check the claim against the market

   Compare the two dates against the published average rates. If their quote is from the spring peak, rates have fallen since, and the request is a negotiation rather than a necessity.

3. 3. Work out what the cut actually costs you

   Take the reduction off your sale price, then off your net proceeds after your agent fee, conveyancing and your mortgage redemption. A £5,000 reduction is £5,000 off your side of the move, not off an abstract number.

4. 4. Check what the buyer has already spent

   Ask whether they have instructed a solicitor, paid for searches, booked a survey and submitted a full mortgage application. Money already spent is the most reliable measure of commitment there is.

5. 5. Decide from three options, not two

   You can hold your price, meet part of the gap, or return to the market. Part-meeting is often the right answer with a committed buyer, and holding firm is often right with one who has spent nothing.

6. 6. Put your answer in writing and set a date

   Give your decision through your agent in writing, with a short deadline for the buyer to confirm they are proceeding. A clear date ends the drift that costs sellers the most.

How do I protect myself while I decide?

Read commitment by what a buyer has spent and instructed, never by what they say. Warmth costs nothing. These do:

• A solicitor instructed and paid on account.
• Local authority searches ordered.
• A full mortgage application submitted, not a decision in principle.
• A survey booked and paid for.

Keep your own spending in step with theirs. Instructing your solicitor early is inexpensive and keeps momentum, but the larger commitments, including paying for a leasehold management pack or committing to your onward purchase, are better held back until your buyer has money of their own in the deal.

A buyer who has paid for searches is negotiating. A buyer who has paid for nothing is still shopping.

What happens if I say no?

Sometimes the buyer proceeds anyway. Sometimes they walk, and you go back to the market. Both outcomes are survivable, and the numbers help you weigh them.

Around 23.7% of agreed sales in the UK collapsed before completion in the first quarter of 2026, according to TwentyEA, so a fall-through is a known risk of every sale rather than a punishment for holding your price.

Against that, Rightmove put the average time to find a buyer at 63 days in July 2026, and there were more homes on the market in August than in any August since 2014. Returning to the market is realistic, and it is slower and more competitive than it was a year ago. Weigh both halves of that.

What is the calm way to handle this?

A rate-driven request for money off is a question, and you are allowed to answer it slowly and with evidence. Get the dates, check the claim, price the decision against your own net proceeds, and read the buyer by what they have spent.
