Signaling a possible turning point in mortgage demand, home equity installment balances rose 0.3% in August - the first monthly increase since November 2007 - according to new data from Atlanta-based Equifax.

Equifax reports that although the total number of home equity installment loans has fallen 43% over the past four years (from 7.7 million in August 2007 to 4.4 million in August 2012), home equity installment balances declined 49% from their $278 billion peak in September 2007 to just $143 billion in August.

Leading the growth in percentage terms in home equity installment loans was New Mexico, which posted both the largest gain in dollar balances (2.3%) and in the number of loans (1.7%) outstanding. California (2.3%), Nevada (2.1), Colorado (2.0%) and Florida (1.9%) round out the top five for percentage growth in balances; Florida (1.6%), Nevada (1.5%), California (1.35) and Colorado (1.3%), which make up the rest of the top five for percentage growth in number of loans.

"The residential real estate market finally seems to be finding solid ground," says Equifax Chief Economist Amy Crews Cutts. "We're seeing signs that the contraction in mortgage debt is slowing and delinquencies continue to trend down at the same time that mortgage rates set new record lows on almost a weekly basis. The environment has been set for growth for a while – now it looks like it may finally be happening."
