Here’s why even modest UK mortgage rate hikes are devastating first-time buyers
House prices in the UK slipped 0.5% in March 2026, erasing the modest 0.3% gain recorded in February and pushing the average property price down to £299,677, according to the latest Halifax House Price Index.
Annual growth also cooled sharply, slowing to just +0.8% from +1.2% the previous month. While Northern Ireland continued to lead the country with +8.7% annual growth and the North East posted a solid +5% rise to £184,119, southern markets weakened further.
The South East fell 1.9% year-on-year to £383,573, and London dropped 1.2% to £536,751.
The culprit, according to Halifax, isn’t a sudden crash in demand butthe quiet but corrosive effect of rising mortgage rates on the most vulnerable buyers in the market.
“House prices fell -0.5% in March, following the modest +0.3 per cent increase seen in February,” said Amanda Bryden, Head of Mortgages at Halifax.
“The pace of annual growth has also eased, slowing to +0.8 per cent from +1.2 per cent the previous month, suggesting the market has lost some momentum as spring begins.”
Bryden pointed directly to geopolitical uncertainty from the ongoing conflict in the Middle East. Concerns over higher energy prices have lifted inflation expectations, which in turn have pushed up mortgage rates.
That shift has dented buyer confidence and delayed the interest-rate cuts many had been banking on earlier in the year.
A headache for first-time buyers
For first-time buyers, even these relatively modest rate increases are proving devastating.
These buyers already face a brutal combination of high average prices near £300,000 and the need to scrape together a deposit, often 5-10% for those stretching every pound.
A small rise in mortgage rates translates into hundreds of pounds more per month on repayments, wiping out the affordability gains that first-time buyers had hoped would materialise this year.
Many are now pausing altogether, waiting to see whether rates will stabilise or climb further before committing.
While UK home sales rose 5.6% month-on-month in February to 102,410 transactions (the highest since March 2025), they were still 5.6% lower than a year earlier.
Mortgage approvals for house purchases increased 3.9% to 62,584, but remained 3.9% below February 2025 levels.
The latest RICS Residential Market Survey painted an even bleaker picture: new buyer enquiries slumped from a net balance of -15% to -26%, and agreed sales fell from -9% to -12%.
Bryden noted that the current rate rises remain far smaller than the dramatic spikes seen during the 2022 mini-budget crisis. Many existing homeowners are protected on fixed-rate deals, shielding them from immediate pain.
Yet for those trying to get onto the ladder for the first time, the psychology is different. Every extra pound on the monthly payment feels like a direct hit to their already stretched budgets.
“The effect on house prices will largely depend on how long-lasting these pressures prove to be and the wider implications for the economy and unemployment,” Bryden said.
“Mortgage rates are a key factor for buyers, particularly those getting on the ladder for the first time, who are already balancing the challenge of saving a deposit, with the cost of borrowing.”
