Buying a house with water issues can be tricky. It is very similar to buying a house that needs new roof or siding. It can either be worked into the deal as a dollar amount off, or it can be contingent upon the sellers remedy to the problem.  Unfortunately, water issues in the basement tend to be an overlooked problem in the house buying world. We get many calls from new homeowners who find water problems that weren’t disclosed. An unfinished basement that needs waterproofing is the best case scenario because it is the least expensive time to do it.
