I can feel like a speed bump in one spot in the room, is that like a foundation beam?

If I were you, so that you become laser focused is to focus on 1-2 markets, so that you understand all of the market fundamentals for each market.

I live in a 100 year old house and had some sagging floors due to the main beam in the house shifting over its life.

If you are dealing with an addition built on 12" beams (or if the original foundation is old and not built to current standards), the repair company might not be able to push the piers down to refusal depth or psi due to the beam not taking the load, thus leveling it, but not guaranteeing it will not continue to move in the future, thus not providing warranty.9.

So you must be laser focused, realistic and do a lot of homework on the ARV of the property you're BRRRR'ing.

I love adding additions to houses with pier and beam foundations. 

They are Asking 1799002 bed 2 full bath (trying to get it back to three bedroom)1694 sq ftHouse needs support beam replaced or at least jacked up and supported better.

Also check for, not just active termites, but old termite damage and dry rot on the support beams as best they are accessible.Sometimes the assessor's office or building inspectors office will have records of when the house was updated.I have some 1900 houses and I like the arch detail, so I  would buy more. 

Inspection biggest finds were a bulging section of the stone foundation and a bowing beam in the cellar both cause slight (but noticeable) slanting of stairs and floor on main level.My main question at this point is who is responsible for the cost of fixing the problem?
