We are looking at a house that had mold, all the drywall, insulation, carpet, flooring,roof were replaced help?

Help please, this home had a water pipe from meter brake in the basement as it was unoccupied/empty, the owner/builder replaced all the drywall, insulation, flooring, carpet, tile, roof, windows, hot water tank, furnace, bathroom and kitchen cabinets, new paint on all, basement ceiling was spray painted black (to hide something or to seal it?). the neighbor says the home was gutted and mold tested three times, its completely redone basically a new home inside, feedback please, it "looks" great
