The tree has caused extensive damage; beams are coming down through the ceiling, the AC is leaking, duct work is coming through the ceiling, roof is damaged, etc. 

For replacement costs on my average deal, HVAC is 3-5K, roof 5-6K, water heater $1K, and foundation can of course vary depending on severity and whether slab or pier and beam as examples.Third, decide if there will be any additions, conversions or demolitions whether adding a bath, converting a room to something else, or removal of walls to open up the space. 

I suspect there are other foundation, beam settlement problem and it is not a 1/4" problem.

I've had a structural engineer look it over and it looks like the main beam may need to be replaced as well as a large number of joists.

If you have shifting or movement of walls and needs piers or beams along an entire wall - call an engineer.

The house is an1800 sq ft pier & beam, 2/2, and located on a large lot. 

I can share some laser-tight criteria that you can pull in List Source to get the best return on your money.

I can connect you with a couple of wholesalers as well, but those deals aren't very laser focused on any specific buying profile... so it could take a very  long time to find the needle in the haystack with wholesalers. 

@Dustin Beam , all of the above.

Thanks @Dustin Beam for your reply!
