In a situation like this, the best way to determine if it has the potential to flood is looking up the FEMA flood maps and secondly, contact an insurance company to see if any claims have been made in the past.The contacting an insurance agent should be done if you have serious interest.
A good home inspector should be able to determine if it had flooded previously. Any mold that is noticed should also be inspected , tested and treated.
If you have any further questions, please call or email me.
