Through December 2009, out of the 1,164,507 trial mods offered to date, only 6% or 66,465 homeowners received permanent loan mods under the HAMP plan.  However, the government claims that an additional 46,000 permanent offers are awaiting borrower acceptance as a result of the the Treasury departments increased pressure on servicers.

Approximately 89% of eligible mortgage debt outstanding is covered by HAMP participating servicers.  During the 4th quarter of 2009, the number of servicers who have signed servicer participation agreements to modify loans under HAMP rose from 63 to 102.

WARNING:  Keep in mind that not every investor or loan pool within a servicer's portfolio necessarily signs up for the HAMP plan.  Investors can opt out on an individual basis.
