An exception could be a structural issue like a post and beam foundation in an old building that could present a funding issue.

Will Barnard I really like your kitchen design as well as the ceiling beams in the living room.

These are just basic numbers I've come up with outside of standard things I want to do when I get the unit (there's a checking beam in the basement, that I want to replace even though the inspector said it would be fine for a few more years since there's been support built into it.

As you probably know sometimes you have to jump to avoid a rollerskate, or duck to avoid a low beam.

Is it post and beam foundation?

If you look at most of the extremely successful RE investors, they laser focus on one strategy.

It looks like you are tearing out the hallway wall, but re-building a new wall in it's place so you may have to temporarily 'shore' the roof joists, but you shouldn't need any beams or anything.I think Thomas' budget of $10 to 15K seems reasonable for my area, but I could see it creeping up to $20k.

Another trick is to place a ball on the floor and see if it rolls in any particular direction as that can be a sign of sinking foundation, failing beams or joists or buckling due to water damage.From there, you need a professional to evaluate your findings.

I think it might need a new cement beam poured and new base-plates & rebars installed.

I may have been laser focused strictly on long term P&I products but the 10 year balloon option is something I never considered.
