The process would be much slower yes, but you would be preventing the debt pile up. 

The foundation was already approved, permitted and finaled years ago for a 3400 sf house, and its solid and I won't be building directly on the overhang edge; but rather back away from the edge a few feet to prevent any load issues all the weight will be on the longer sides of the existing footing.

While it can feel like a hassle, these inspections help prevent bigger (and costlier) problems down the line.

It might be worth talking to a lawyer but not sure if it's small claims or worth it.Also, you might already have all of these things but for future prevention:- smart thermostat (so you receive alerts when the inside temperature dips below whatever preset you have)- Minut (or similar device) would also alert you to the inside (and outside) temperatures; for example, I have 2 devices inside the house and outside on the hot tub deck.

Condo bylaws prevent airbnb usage, so not that.

What specifically did you expect them to do to prevent them?

This contract includes an exclusivity clause to prevent your clients from bypassing you and going straight to the lenders to cut out your commission. 

If multiple people chose another house for the same reason or avoided yours for the same reason, maybe you can pivot a little to prevent that issue being a factor for future prospective renters. 

Having a strong understanding of your "walk away" price (maximum you're willing to pay) gives you leverage and prevents emotional decisions. 

BUT there was nothing preventing DOCUMENTATION.
