The Charleston region is witnessing rising home sales, developers shaking cobwebs from once-stalled new projects and area banks adding staff to meet mortgage demand.

So, what's another indication that the Lowcountry's housing front is rebounding? Real estate firms are expanding.

Keller Williams Realty Inc., recently opened a West Ashley office at 1180 Sam Rittenberg Blvd., marking the firm's second office in the region.

“We are experiencing unprecedented growth at Keller Williams Realty; our associate count increases by an average 1,500 a month,” said Mark Willis, chief executive officer of Keller Williams Realty International.

Real estate firm RE/MAX also is planning three more locations this year in the region, according to Eddie Sturgeon, the company's business development consultant for the Carolinas.

Real estate firms and banks retrenched when the housing crisis sent things into a tailspin years ago.
