This followed after a 2X overflow of a tenant on a first floor that flooded his bathroom using a portable washing machine and flooded the basement apartment.

The longest delay is the floor plans. 

Through your local bank that you are using, are you reapplying for each new home for a seperate construction loan or are you setup as a credit line with them and just submit a new budget for each new home 7 mil credit line  ... new budget for each plan that has been pre appraised in the MAI at the beginning of the project.. they did have to update the Mai last summer but again did it at their cost not mine.. banks have to paper their files.. even though we are selling the same floor plans for 100k more per plan than the original numbers came it at and bank has been paid and has all the closing statements showing this data..

It takes longer to get up and down on floor than it does to tighten bolts same goes for seat.

., same tile, paint, flooring, etc.

For example, the 2nd to last photo of a random wall and floor with part of open door; what is that supposed to be telling?

Definitely get the structural engineer to look at the joists & support beams to see what's up with the uneven floors.

We do lower rates, and I'm curios if others have run into a "floor price" below which you just get problem guests.

Some need new furnaces, flooring, and paint.

That's already in the law and applies to floors, windows, lawn, etc.
