Also, the price projections in the study are based, in part, on the fact that the ratio of purchase prices to annual rents is still higher in many areas than the historical average, which is roughly 15 times rents. While past figures may well have some predictive value, I have never been convinced that first-time buyers compare a home that they could own and one that they would rent in purely or even primarily economic terms.

When Jaime and Michael Proman moved this fall to Minneapolis, his hometown, from New York City, they craved a different sort of life after two years together in a 450-square-foot studio apartment. “We didn’t want a sterile apartment feel,” said Mr. Proman, who is 28 (his wife is 26). “We wanted something that was permanent and very much a reflection of us.”

The fact is, in many parts of the country there are few if any attractive rentals for people looking to put down roots and enjoy the sort of amenities they may spot on cable television home improvement shows. Comparing a rental with a place that you may own seems almost pointless in these situations, especially for those who are now grown up enough to want to make their own decisions about décor without consulting the landlord.

The basics are back, like spending no more than 28 percent of your pretax income on mortgage payments, taxes and insurance. Even if a lender does not hold you to this when you go in for preapproval, you should hold yourself to it.

You will also want to start now on any project to improve your credit score because it may take several months to get it above the 720 level that qualifies you for many of the best mortgage rates.

John Ulzheimer, president of consumer education for credit.com, a consumer credit information and application site, suggests starting to pay down and put away credit cards months before you apply for a loan. That is because the credit scoring system could penalize you if you use a lot of credit each month, even if you always pay in full.
