It appears that I will need to have a single tenant for the entire building,  or at the very least one tenant to lease the 1st and second floors otherwise the compliance issues would be too onerous to be practical... i.e. if separate tenants for each floor, a 3rd floor office tenant would need an elevator installed at a min cost of $80k if it was even possible.A challenge being that he is disabled.

He must have redesigned the elevations a dozen times, none of that was at our direction.

This surprised me since the property was not near any creeks or mountains and is even in a little bit of a hilly area and it is not at the lowest elevation.

On decorating, my first reaction is that the aesthetics in the back don't match the front elevation and the interior, which both look great.

The other couple of banks that I considered going with were First National, Elevations Credit Union, Key Bank. 

Not much you can do for the water infiltration/sewer back up issue; I would say it happens every 8-10 yrs in Euclid (Euclid is close to Lake Erie where all higher elevation suburbs' storm run-off have to go thru city's sewer system; if your property is north of I-90 then you are at risk).

Like @Jd Martin had mentioned from what you're describing you have what they call a sewage ejection pump installed due to elevation differences from the lower bathroom area.

I've looked at quite a few MFs lately that are doing much worse than 50% expense ratios due to elevated vacancies, distressed units needing rehab that the owner can't afford, and very high turnover-related expenses.These situations call for apartment turnaround specialists, which I don't claim to be, but clearly units can be bought for $7-12K each all over fly-over country and someone who knows what they're doing can do very very well against a backdrop of rapidly rising numbers of renters in years ahead, due to tightening lending standards and so many more people with blighted credit.

I step off the elevator and Rich practically throws me out of the hotel saying "go home, it's over!"

The reason for this is that many contractors try to hide elevated labor cost in their estimates along with supplies.
