UK house prices fell for a second consecutive month in April, as Halifax halved its estimate for the annual rate of growth owing to the conflict in the Middle East.

Halifax, which is part of Lloyds – Britain’s biggest mortgage lender – said that the cost of a typical UK home fell by 0.1% in April, to £299,313. This followed a 0.5% fall in March.

Halifax said the annual rate of house price growth had slowed to 0.4% from 0.8%.

Amanda Bryden, head of mortgages at Halifax, said: “After a strong start to the year, recent global developments have added a greater degree of uncertainty to the outlook.

“In particular, higher energy prices have fed into inflation expectations, prompting markets to reassess the path for interest rates – a shift that has already pushed up borrowing costs for many buyers.

“This understandably leads to more caution among some households, with the cost of living once again front of mind and extra thought being given to planned property moves.”

On Thursday, the average two-year fixed mortgage rate stood at 5.77%, up from 4.83% at the start of March, according to Moneyfacts. The average five-year fixed rate mortgage was 5.69%, up from 4.95%.

Before the conflict in the Middle East, the UK housing market had shown solid growth this year, with the price of an average home rising 0.8% month-on-month in January and 0.3% in February.

The strong start to the year had led Halifax to forecast 1.2% house price growth on an annual basis in February.

“The problem facing the market at the moment is that many sellers are still pricing based on expectation rather than current market reality and that’s creating a growing disconnect between buyers and sellers,” said Chris Hodgkinson, managing director of House Buyer Bureau.

“Whilst demand is still there, buyers are far more price sensitive in the current climate and homes that aren’t positioned correctly from day one are simply sitting on the market for longer, forcing sellers into larger reductions further down the line.”

The economic turbulence caused by the Middle East conflict has created huge uncertainty in the housing market.

Last week, Nationwide’s surprised estate agents and economists by reporting that house prices had jumped in April at the fastest annual pace in 11 months.

The UK’s biggest building society said its mortgage data showed that house prices unexpectedly rose by 3% in April compared with a year earlier, from 2.2% in March, making the typical UK property worth £278,880.

Nationwide, which measures activity in the housing market differently to Halifax, has recorded four consecutive months of price increases.

The lender reported a 0.4% rise in April after a 0.9% increase in March. City economists had been expecting a 0.3% monthly fall.
