Interior Drain Tile and Foundation Questions

[Kyle B.]

I have questions for two different homes I have seen and am hoping to get some advice from the BP community. I apologize for the long post in advance.

My first question is regarding water seepage in the basement of the first home. The home currently does not have gutters, so I was told installing these would more likely than not fix the problem, but worst case scenario is that I would have to install an interior drain tile which I was given a rough estimate of around $3-$5k. In a case like this, should my offer price simply incorporate this projected expense or is there a better way to determine whether or not a drain tile is necessary before making an offer? Up to this point, I'm getting my information from a plumber who verified no leaks in the current piping, and that adding gutters would probably fix things - but there was no way to know for sure until installing the gutters and seeing what happens after a heavy rain.

Second questions is regarding a foundation issue for a ranch style house. In the basement, the foundation has a crack along several of the walls, where it is bowed in slightly. For people who have dealt with this issue before, what were the costs associated with this fix? Obviously will depend on each situation, but just trying to get a ballpark figure.

Thanks!
