Mortgage rates are about a full percentage point higher today than they were at the beginning of March. The average rate on the 30-year fixed hit 4.80 percent by the middle of last week, according to the Mortgage Bankers Association. That is the highest since April 2011.

Rates have been trending higher on expectations that the Federal Reserve will begin to taper its investments in mortgage-backed securities.

Home prices are also trending higher in part due to the fact that there are fewer distressed properties for sale. Excluding distressed sales, prices were up 11.4 percent year over year. Distressed properties have seen big price jumps in the past year, as investors fight to get the remaining bargains.

Markets hit hardest by the housing crash have seen some of the biggest price gains: Nevada home prices were up 27 percent annually in July, California up 23 percent and Arizona up 17 percent. Completed foreclosures nationally were down 25 percent in July from a year ago, according to CoreLogic.

Prices are also getting a boost from the sheer lack of properties for sale. Inventories are way down in local markets across the nation, and home builders are not ramping up production fast enough to meet new demand.

While the inventory situation is not expected to ease very much over the next year, home prices are expected to weaken slightly, as higher rates and weak income growth put a cap on just how high prices can go.

“We can thank investors for that limited inventory, of course, as many entry-level buyers are now going to have no choice but to rent,” said Peter Boockvar of The Lindsey Group.

Even as investors move out, cash is still king in this market. Thirty-one percent of sales were all-cash. That share is usually below 10 percent. June’s home sales were largely unaffected by the recent rise in mortgage rates, as contracts for those sales were signed in April and May.

The Realtors’ group expects higher rates to slow sales in the coming months, and if investors, who drove the market for so long, continue to exit, those sales could be even slower.

“Buyers buy based upon payment, and those payments are still highly affordable relative to their incomes,” he said. “Even with 100 basis point swing, there’s still plenty of room in that [affordability] index.”

The concern, however, has been that as mortgage rates rise, home prices would necessarily fall, as buyers lose purchasing power. That may not be the case, according to a new analysis.

“History shows that a rapid rise in interest rates tends to have little correlation with home prices. Rather, rising rates are more likely to contribute to a decrease in home purchase volume and an increase in the market share of adjustable-rate mortgages,” wrote Mark Palim in a Fannie Mae commentary.

“This reflects a characteristically volatile multi-family sector rather than renewed weakness, and we expect homebuilding volumes to rise further later this year,” wrote Paul Diggle of Capital Economics.

Housing starts fell 9.8 percent, but the drop was entirely in apartment construction, which accounts for 30 percent of all residential construction activity, according to the U.S. Commerce Department. Multi-family starts fell by 26.2 percent in June compared to May. Single family housing starts fell by just 0.8 percent month-to-month.

“Should we be concerned? Not yet,” wrote Patrick Newport of IHS Global Insight. “Builders are still not putting up enough homes. Far from it. By our estimate, underlying demand is running close to 1.4 million. Meanwhile, housing completions in July were 755,000 [annual rate], while housing permits were 911,000.”

Listings were down 17 percent in March from a year earlier, according to the association, with several factors affecting inventories. Millions of Americans still owe more on their mortgages than their homes are worth, and that makes it impossible for them to move without incurring major expense.

Others are watching home prices rise and may be waiting to see just how high they go before listing their homes.

Meanwhile, home builders, while trying to ramp up production, are faced with a lack of land, labor and materials. Single-family starts were at a seasonally adjusted annual rate of just 619,000 units, an improvement from the worst of the crash but far below historical norms.

Regionally, the pending home sales index was unchanged in the Northeast from February, up 0.3 percent in the Midwest, up 2.7 percent in the South and up 1.5 percent in the West.

Existing home sales in March, based on closings, fell just under one percent in March. While higher than a year ago, home sales appear to have leveled off, despite this being the normally busy spring season.
