A couple other questions I would have - What's the age of the home and is the foundation slab or pier and beam? 

We were doing this huge project and found a bad beam in the ceiling.

.$6500 / $300 month higher rent = 22 month recovery.Typically, anything in the 3-5 year recovery range is worthwhile.WARNING: who is going to determine how to add the proper support beam when the wall is removed?

The main beam in my basement still has bark on it.

I also had an inspector discover that the center support beam was completely destroyed by dry rot on one property and the only way to get a new beam in would be to take off a sizable section of one of the outside walls to the house because the basement was too small to get the beam in through the one door into it and then turn the beam to the correct direction.

Anyway, do any of you have experience with finishing basements with these beams?

@Ben McMahon inspector is telling me he suggest some support beams to be added down the middle of the home.

Send someone under the house with these to take lots of pictures of the floor system to include the plywood or planking deck, joists, and beams with the meter stuck in the wood in the photo. 

My internet provider has that which is handy because we have our gear mounted to a beam in the ceiling (don't ask). 

My structural engineer already drafted up a plan with new girders/ beams to give a better support.I’d really appreciate any foundation contractors referral.
