I’m in a contract to buy a house, and the closing is in two days. It rained hard the night before my walk-though. When my broker and I entered the house the next morning, we saw a stream of water running from a drain outside, going under the patio door and through the living room. In addition to whatever caused the leak itself, which has not been determined, the basement carpet is wet and stained. We’re negotiating with the seller to pay for repairs, but how exactly will this be handled financially, with the closing so soon?
