Keystone management will remain intact as will the regional offices and 19-employee servicing center, GMAC's Scott Rombach told GlobeSt.com. The acquisition is strictly being done to beef up the nation's leading commercial mortgage banker's presence in the southwest and the life insurance end of the mortgage industry. "We thought it should be stronger," he explains of the motivating factor to acquire Keystone.

GMAC, says Rombach, is always looking for acquisitions. Just last week, the banker had closed on a takeover in Memphis. Keystone's buyout firms up GMAC's plans for now with regard to the southwest, says Rombach. "But we're always open to available deals," he says, careful not to rule any prospective deals for the region.

The Dallas servicing center marks a first in the southwest for GMAC. Its other centers are located in its headquarters city, Chicago and Richmond. Keystone originates more than $1 billion in commercial mortgages annually and maintains a servicing portfolio of more than $2 billion.
