A number of real estate franchises now offer to foot the costs of renovations and repairs, agreeing to be paid when the sale closes. But late this summer, the Coldwell Banker chain expanded its RealVitalize program to its entire network of some 94,000 agents in 3,000 offices. With RealVitalize, listing agents connect their sellers with a dedicated project consultant from HomeAdvisor, which matches homeowners with local service professionals. The brokerage will cover the upfront costs of the repairs, which will be repaid by the seller when the sale closes or the listing expires. Meanwhile, Curbio, an independent presale renovation company based in Maryland, works through real estate agents -- regardless of their affiliation.
