The lagging sector is new single family homes, where a shortage of skilled labor and buildable lots is holding back construction. Thinkstock By David Payne, Staff Economist November 18, 2014 Eight years after heading into the tank, the housing market is finally nearing normal. Come 2015, sales of existing homes are likely to match or top the average for 1999-2002, before home buying mania seized the U.S. A strong rental market already has the construction of multifamily dwellings back to that historical norm.See Also: 10 Markets Where Housing Prices Have Risen the Most The big exception is new single-family homes. Both construction and sales of them are running at just 50% of their pre-bubble levels, and they won’t regain those norms until at least 2017. Demand is lagging for a couple of reasons: New homes tend to be more expensive than older ones, limiting the pool of buyers with the credit to buy them. And a paucity of first-time buyers means fewer owners of existing homes are able to sell and move up to a larger, more costly home. But supply is also a constraint. Builders can’t keep up even with the currently muted level of demand, according to the National Association of Home Builders.. These days, a new home typically sits on the market for just three months versus the four or five of the past. There aren’t enough skilled tradesmen: carpenters, framers and others who left the field in droves when the bubble burst. There are too few build-ready lots. It takes 15-36 months to prepare sites—building roads, water and sewer lines, bringing in electricity and so on, plus clearing regulatory hurdles. In some localities, jumping through the regulatory hoops alone can take up to seven years. Making matters worse, many lenders—gun-shy after the steep plunge in housing prices—have been loath to lend for development of raw land. So only builders with deep pockets are able to create new subdivisions. Though all these pressures are easing, it will take time for them to disappear. Meanwhile, for the housing market as a whole, several positives are at work: Credit is getting easier. Half of mortgage lenders surveyed expect improved access to credit for lower prime borrowers (FICO scores of 620 to 720) over the next six months. Lenders are becoming more comfortable with the standards for loans that can be off-loaded to Fannie Mae or Freddie Mac, soothing their concerns. (Parallel rules for mortgages that can be securitized and sold will kick in next year.) So there’s more flexibility on debt-to-income ratios, and minimum down payments are sliding from 5% to 3% for Fannie- and Freddie-conforming loans, for example. Of course, compared with the boom years, mortgages are still much harder to obtain. About half of mortgages still go to borrowers with FICO scores above 740. Though that’s better than the 60% such borrowers accounted for in 2013, it’s far more restrictive than in the early 2000s, when the average borrower score was 680. The Federal Reserve’s July 2014 Senior Loan Officer Opinion Survey on Bank Lending Practices indicated that half of mortgage loan officers considered conditions still to be tighter than average. Also helping are higher incomes and employment; more consumers can afford purchases. In addition, there are a million more potential home buyers than usual—a backlog of young adults still living with their parents but eager to strike out on their own as soon as possible. Mortgage rates will remain modest, despite a likely slow climb over the coming year. As for prices, we expect them to increase more slowly in 2015, now that the first pendulum swing from downturn to upturn is over and investors are seeking better returns elsewhere.
