Topographical survey in flood plain?
A house I'm interested in is in flood plain. The seller's agent (yes, seller's) recommended at the open house that we get a topographical survey, or that we ask for one as part of the offer. It's a house being sold by executors of a woman who passed away.
I understand that it would show what part of the property might flood or not, but why else would I want this? I've lived on sand near a lake for years and this is new to me. Anyone hear of it before?
