Will your home gain value over the next 12 months? Nobody can know for sure, of course, but should recent housing trends continue, there’s concrete cause for optimism.

The housing economy has suffered since 2007, knocking home values down nearly 20% nationwide. And while some areas have fared better as compared to others but, in general, home values are down.

Mortgage rates are down, too, and that’s good news for buyers. The combination of low rates and low prices has led home affordability to an all-time high. As you’ll hear in this 4-minute interview with NBC’s The Today Show, carrying a mortgage costs 25% less per month as compared to just 3 years ago.

Some other notes from the interview include :

• There are more buyers out looking for homes today, which leads to more sales
• The housing market is expected to get gradually better, month-by-month, in 2012
• Foreclosures will continue to be a big part of the housing market

With housing supplies shrinking, buyers may find their best “deals” today — before the Spring Buying Season begins in February.

However, we can’t forget that housing markets are local — not national. Each town and neighborhood has its own market drivers and prices where you live may have already started to climb.
