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.

A foundation company installed beams and did epoxy injected cracks couple years ago.

I was only expecting one wall to be load-bearing during my original walk-thru and the wall that I did not realize was load barring required a very large beam that lead to us having to open another wall to support the beam.

If the floor is level on concrete vs pier and beam house.  

This is not with a steal beam, just wood, and a column in the middle.

This all needs some investigation.I see a few options, in two main veins:Piecemeal replacement:1) Jack a section from the inside by attaching a support beam to the studs and take enough pressure off the structure to knock out all the rotten wood, cut and sister the bad studs and put in pressure treated lumber.

We have our first two duplexes under contract and are completing inspections.After the general home inspections, a few minor issues were found like a couple of plumbing leaks, a roof leak, couple of venting issues, a split beam in the attic.One of the HVAC units didn't come on when tested, so that's a possible issue.

If you want to laser-focus your efforts, REOs are probably easier.

Now, the Pareto rule states that 20% of the activities generate 80% of the results, so I try to laser focus on those line items.

Helps you to laser focus on some of those properties.Good Luck!
