The real estate slump (in Atlanta) and elsewhere is likely to worsen, given that most of the adjustable rate mortgages written in the last three years will be reset with higher interest rates, said Christopher F. Thornberg, an economist with Beacon Economics in Los Angeles. As a result, borrowers of an estimated $800 billion in loans will be forced in the next 12 months to 18 months to make bigger monthly payments, refinance or sell their homes.

A big reason the fallout is occurring faster here is a Georgia law that permits lenders to foreclose on properties more quickly than in other states. The problems include not just people losing their homes, but also sharp declines in property values, particularly in lower-income and working-class neighborhoods.
