@Taylor Chiu  I currently work in the healthcare field and did home health for a while and saw patients in numerous ALF's in SFR here in california. 

Again, thanks for your help and explanation.  

There are some exceptions as to when you can get away with a single stair (full explanation below) but you'll see it is not easy to do.I actually used to live in/rent a third story attic space with a single stair, and as a tenant I thought it was fine.

You seem to have a lot of competition in your field, but you keep plugging along.I've bought numerous homes on the private market, and I wouldn't have it any other way.

and what was their explanation? 

I keep hearing how people are cost segregating, but I have pushed my accountant numerous times on this and he just saying that if we did the cost seg, all of that depreciation would just go into a reserve that would then be applied when we sell the home. 

But it could be numerous reasons...

Assuming I had the experience, I would only buy a place with structural issues if I had 1) an experienced and trusted structural engineer telling me a clear, and verifiable explanation of the cause(s) of the problem and a viable and affordable solution, 2) trusted and experienced tradespeople who would be implementing the solution (carpenter, mason, etc.) confirming with me that they could fix the issue (with 90% or higher confidence that the issue could be resolved within budget), and 3) confirmation from city inspectors that the issue (and an inability to fix the issue) would not result in condemnation/revocation of occupancy permits. ...and even then, I'd only proceed if I had the cash reserves to ride out a major series of unexpected problems (e.g.; time overruns, budget overruns, unexpected revocation of occupancy permits from the city, etc.) 

This past year there have been numerous disagreements, arguments, difference of thinking, etc which drove us to wanting out.

I've bought numerous properties with none of my own money - but you have to work to find these deals and make a lot of offers, and hear a lot of no's.
