The boom in buy-to-let investing has had only a moderate impact on rising house prices, new research has found, challenging the belief that buy-to-let investors have priced first-time buyers out of the housing market.
The rush of buy-to-let investors on to the housing market, particularly since 2003, pushed up house prices by an additional 7 per cent, according to an independent body that advises government on housing market affordability.
The study, from the National Housing and Planning Advice Unit, suggests the flood of new buy-to-let mortgage issuance in the past five years is not responsible for the sharp drop in first-time buyers over the same period.
Buyers of an average house today who took out a 100 per cent mortgage are making monthly payments just £90 higher than if there had been no buy-to-let investment, the NHPAU says. If buy-to-let lending is stripped out, the average house price in the second quarter of 2007 would have been £169,000 rather than £183,000. Interest rates, the rising number of households and constrained supply have been far greater contributors to house price inflation, the study concludes.
Analysts Capital Economics agreed in a report last week that the impact of buy-to-let investors had only been one factor pushing up house prices, but suggested that buy-to-let investors had prevented the market softening sufficiently to allow new buyers on to the housing ladder. Capital Economics found that buy-to-let now accounted for one in every 13 mortgages; at the end of 2003 the ratio was one in 27 loans.
The findings suggest that the key for first-time buyers was affordability, defined as the proportion of national average take-home earnings absorbed by a new mortgage. In 2003, rising interest rates and declining affordability led to a drop in first-time buyers, as it had in previous cycles. But unlike previous cycles house prices continued to rise, a trend that Capital Economics believes was strengthened by the presence of buy-to-let investors.
However, both Capital Economics and the NHPAU conclude that buy-to-let investors had on balance made substantial contributions to the quantity and quality of the private rental sector in Britain.
“In any analysis of BTL, it is important to consider the wider benefits [to the economy],” said Stephen Nickell, chairman of the NHPAU. “Together with the regulatory changes in the 1980s, the expansion of BTL lending has supported growth of the private rented sector, which now provides homes for 3m households. Increased competition has kept rents low relative to house prices.”
The studies also examine how buy-to-let investors might behave if house prices start to fall. Without the assumption of continued increases, investors may chose to sell.
“Given that BTL investors have boosted house prices during the boom, the likely drying-up of new investor demand is another reason to expect house prices to fall back in the coming years,” Capital Economics said.
Weakening market for homes
UK house prices were unchanged in January and 1 per cent lower than they were in the previous quarter, according to the Halifax House Price Index, in yet another sign of a weakening market for homes, writes Norma Cohen.
On an annual basis compared with the same quarter a year ago, prices were 4.5 per cent higher to the end of January – the lowest annual rate of inflation since late 2005. This compares with an annual rate of 5.2 percent in the three months to December and a peak of 11.4 percent in the three months to August.
Halifax said its forecast for 2008 was for house prices to remain flat, rather than slumping. It noted that the number of people in employment – a key driver of housing demand – had risen to a record 29.36m over the past year.
Martin Ellis, chief economist, said: “We expect sound economic fundamentals and lower interest rates to support house prices,” adding that he expected the Bank of England’s monetary policy committee to cut rates twice in the coming year.
