WASHINGTON — U.S. home sales picked up slightly in February but remain sluggish due to tight inventories, affordability problems and nasty winter weather.
Sales of existing homes rose 1.2 percent last month to a seasonally adjusted annual rate of 4.88 million, a slight rebound after plunging in January, the National Association of Realtors said Monday.
The real estate market has hibernated through the first two months of 2015. Strong job growth and relatively low mortgage rates have failed to awaken buyers. Meanwhile, relatively few homes are being listed for sale and builders are mostly catering to the wealthiest slivers of the market. Sales are running below last year's pace of 4.93 million, which represented a 3.1 percent drop from 2013.
Despite February's uptick, buying activity appears to have been slow coming into March because of a series of harsh winter storms. The weather last month shut down construction and hurt open houses, likely putting a limit on buying activity this month.
Housing starts plunged 17 percent in February, the Commerce Department reported last week. Buyer traffic also slipped last month, according to the National Association of Home Builders/Wells Fargo index. Mortgage applications slipped in March, according to the Mortgage Bankers Association.
Sales tumbled 6.5 percent last month in the Northeast, which was hammered hard by snow, the Realtors said. Home-buying was unchanged in the Midwest and increased in the South and West.
The recent storms have led several economists to expect a strong recovery in the coming spring months, when more buyers usually step up their search and sellers decide to list their properties.
Still, some homeowners are trapped by mortgage debt, making it unprofitable for them to sell. Their negative equity is a lingering aftershock from the recession and housing bust, limiting the supply of available homes on the market.
The real estate data firm Zillow reported last week that 16.9 percent of homeowners owe more on their mortgage than their homes are worth. In several metro areas including Philadelphia, Houston and Boston, that rate actually increased from the levels in the third quarter of 2014.
The Realtors reported Monday that just 4.6 months of supply was listed for sale, compared to a full five months a year ago.
That meager inventory has helped push up sales prices, creating additional affordability pressures despite strong monthly job gains averaging more than 200,000 for the past year.
Median home prices increased 7.5 percent over the past 12 months to $202,600, almost quadruple the pace of average hourly wage gains.
Sales to investors and for all-cash have also declined over the past year, while first-time buyers have yet to return. First-timers accounted for only 29 percent of home sales, compared to a historical average of 40 percent.
Nor have buyers responded much to the comparatively low mortgage rates.
Average 30-year fixed rates were 3.78 percent last week, according to the mortgage giant Freddie Mac. That average has plunged from a 52-week high of 4.41 percent, which should help to make housing more affordable.
Because of tight credit, few potential buyers have been able to take advantage of the low rates.
An Urban Institute index measuring credit availability found that lenders are taking fewer risks with mortgages, choosing buyers with high credit scores and providing them routine mortgages, rather than the exotic and opaque loans that inflated the housing bubble and led to the financial crisis.
The restricted credit "has been, and threatens to continue to be, a headwind for the housing recovery," said Michelle Meyer, a senior economist at Bank of America Merrill Lynch, in a client note.
