I love the condensed insight we get in this: Last Tuesday the Case-Shiller Home Price Index for 20 cities came in UP a seasonally adjusted 0.4% for October. This was the fifth consecutive monthly increase for the index. Year-over-year, prices are still down 7.3%, but that’s a less steep rate of decline than we’ve been seeing.

It looks like home prices could be stabilizing, though well below their peaks in most markets. This price decline, plus the dramatic drop in mortgage rates, have made homes more affordable than they’ve been in a long time. A writer for the Wall Street Journal compared home price index values, mortgage rates and average weekly earnings going back to 1987. The finding? On average, housing is as affordable now as it was in the mid-1990′s, when homes were a real steal. Of course, this conclusion is based on average prices, so affordability may be greater or less in individual markets.

Christmas Eve, the Treasury lifted the limit on the money it can put into Fannie Mae and Freddie Mac to keep their net worth positive over the next three years. Some economists point out that Fannie and Freddie could now replace the Fed as a big buyer of mortgage-backed securities to help keep mortgage rates down after March 31. That would be great, but nothing is certain. Smart buyers are taking advantage of TODAY’S low mortgage rates AND the expanded tax credit that requires a signed contract by April 30 and a closing by June 30!
