UK house prices fell 0.5% in March, reversing February’s 0.3% rise and leaving the average property value at £299,677, while annual growth slowed to 0.8% from 1.2%, according to Halifax.
For landlords, the more useful takeaway is not the monthly dip on its own but what caused it. Halifax said wider uncertainty around the conflict in the Middle East pushed up inflation expectations, fed through into higher mortgage rates and dented buyer confidence just as the spring market got going.
Halifax says higher mortgage costs are cooling buyer demand
Halifax said recent mortgage rate increases have been modest compared with the disruption seen after the 2022 mini-Budget, but still significant enough to slow momentum. That matters for landlords weighing purchases, refinancing or exits, because borrowing costs remain the key pressure point even where underlying housing demand has not collapsed.
Amanda Bryden, head of mortgages at Halifax, said: “The recent slowdown in the housing market reflects the wide uncertainty regarding the conflict in the Middle East.”
Nathan Emerson, chief executive of Propertymark, said: “We are at an important intersection where we must clearly acknowledge future challenges ahead.”
Emerson said a run of sub-4% mortgage deals had been withdrawn in recent weeks and warned that inflation, Bank of England rate decisions and the next Ofgem energy cap update could all weigh on affordability through the rest of the year.
Ryan Etchells, chief commercial officer at Together, said: “The mortgage market’s sudden about-turn in March has definitely rattled would-be buyers, and it’s starting to push house prices down as a result.”
Jonathan Hopper, chief executive of Garrington Property Finders, said the first warning light on the market dashboard had switched on but described it as “amber rather than red”, arguing that one month of data was still too early to call the direction of travel with confidence.
This follows Landlord Knowledge’s report on the Bank of England’s warning that 5.2 million borrowers face higher mortgage costs, which highlighted the squeeze from rising repayments. Combined with Landlord Knowledge’s recent coverage of house prices remaining 7.6 times average earnings, the latest Halifax figures suggest affordability is still fragile even before any further inflation shock feeds through.
What the March house price dip means for landlords
For buy-to-let investors, this is less a story about a collapsing market than a reminder that price growth and deal flow are becoming more rate-sensitive again. Landlords with cash or lower borrowing may still find opportunities if sellers trim expectations, but heavily debt-reliant buyers face a narrower margin for error.
There is also a timing issue. If inflation stays sticky and mortgage pricing remains elevated, the spring selling season could soften further. That would not automatically be bad news for landlords looking to negotiate, but it does increase the risk of overpaying if financing assumptions are based on rate cuts that do not arrive quickly.
What this means for landlords
- If you’re buying this spring: stress-test deals against mortgage rates staying higher for longer rather than assuming an early cut.
- Watch for: further lender repricing, Bank of England signals and the next inflation prints, all of which could move affordability quickly.
- Bottom line: the market is slowing rather than seizing up, but landlords relying on debt need sharper pricing discipline than they did earlier in the year.
Editor’s view
The Halifax dip matters less as a headline and more as a warning about funding conditions. For landlords, the key risk is not that values suddenly fall away, but that mortgage costs stay high enough to choke off weak deals and punish anyone still underwriting purchases on optimistic rate-cut assumptions.
