Properties that are zoned mixed-use or commercial can be an exception.

We barely found this new build home at $375k and I was almost forced to take it because everything in the area was sold out, except for this one that was a fallout.

The one we are buying is 1.6M so...He said no exception would work for us unfortunately.

We did NOT have any appraisal contingency and got the deal excepted, so if we hadn't appraised, we would have gone back and renegotiated.

I'm looking to purchase something there and the math so far is not mathing real well for me, especially looking at the fact you can't do any STRs except in the commercial district. 

Exception to the Rule: Using a title like ‘Work from Home’ can get you a large response because the value to the applicant is present in the title before they even click on it.

The numbers didn't change & have actually done exceptionally better this year.

Based on the limited information you've provided, as long as there's no exception in the title policy for a claim made by the ex, if he does make a claim to the property post closing, it sounds like it should be a matter covered by the policy. 

Walls two and three are shared, (except corner units) wall four has bedroom windows.

It sounds from your description that you could also be eligible to use the last principal residence exception to withholding.
