If you're concerned, it’s a good idea to clarify with your lender or shop around for one with more lenient requirements.

I have also heard concerns about removal and tampering with these devices. - Water: I'm currently including water in rent for both of my buildings, because I've luckily not had to meter my water use.

Yes I'm concerned about the more wasteful tenants.

There are no other safety concerns or visible signs of the fire left intact.

The only item of concern is the line about a "minimum of 1-acre".

That assumes beachfront -- oceanfront, of course, doesn't have that concern (but may have others).

I put that project on the back burner since higher development costs and thin margins were already causing us concern. 

Maybe I am miss understanding your concern... a Non-Disparagement Clause normally means that you will not publicly speak bad about each other.

I'm only concerned with the financial logistics to get the mortgage in my name rather than theirs.

If they are overpaying and you are concerned with turnover, then I would help them out with the landscaping.
