On the current path, home prices, sales and construction should continue upward, said economist Jed Kolko of Trulia. Meanwhile, vacancies, delinquencies and foreclosures will be dropping. “Inventories may be down too as a necessary part of the housing recovery.”

Homes are still undervalued relative to rent, Kolko said, and a full housing recovery is a few years away.

Currently there are no signs of over-building and little sign of over-borrowing, he said. “Prices would have to rise at current rate for several years to return to bubble territory.”
