I'm house shopping and all the houses seem to have some kind of issue. Ugh. The latest one looks great until you get to the basement where there is evidence that water has been in the basement (water lines along the bottom of the old drywall). Barring any kind of structural issue, what is the worst case (most expensive) scenario to correct the basement flooding? Exterior French drain?
The house is well priced about $20k below market so I'm actually considering putting in a low offer even with the basement. The seller will not consider fixing it.
