Credit Still The Key 

In the recent past, the biggest problem with lenders was being sure they didn't lure you into a mortgage with a payment that was too large, or a loan that didn't amortize, or an adjustable rate mortgage for borrowers for whom it was inappropriate.  Foreclosures on mortgages with those characteristics are rising, so lenders are getting more careful.  They are raising requirements for credit scores, and cutting down on 100% financing and low (or no) documentation loans.  Having good credit is becoming more important for home buyers again.  If yours is less than ideal and you want to buy a home, begin work to improve it as soon as possible.
