Cost of Piering the Foundation

[Carrie Hallensleben]

We are considering whether to buy a REO that has major foundation problems. We've looked at the comps but aren't really sure about how much to allocate for piering. I called one place and it was 1200 per pier. We had our own basement done and that sounds on target. I'm not sure how far apart they are usually placed so as to get an estimate.

There are huge cracks throughout the house. There is a finished basement next to a subbasement and everything above the subbasement seems stable but the slab on the finished side has cracked. Here are some photos I put together in a Google doc. https://drive.google.com/open?id=0B0hhDVxbmkfJUTlLT2pyVFNaUUE&authuser=0

I'd appreciate any insight you have that would help us determine cost of worst case scenerio.
