I know this would likely have some impact on depreciation as well as refinancing.

Non ad valorem would be taxes that are evenly applied to all properties regardless of value on a per-property basis, commonly for community road improvements, new fire stations, CDD (community development district), or other items like that which impact a small part of the county which those seeing benefit repay over a period of time.

It will depend on whether or not the property looks like a crypt itself that would have more of an impact.

But that’s not the case here.What you’re describing is a situation where a tenant had personal property damaged and is trying to force the landlord to pay for it by deducting the cost of that property from their rent.

It is also in between both Nellis and Creech Air Force base so many Airmen and their families look to rent in this area.

To your point however it doesn't seem to impact the monthly cash flow number and only impacts the "profit if sold" metric.

I doubt it would boost the re-sale by by much more than $2,000, and it may have $0 impact on an appraisal. 

The first time the market had dropped and we were forced to rent the property.

You may want to calculate the gain situation and think about reducing price a little to force a sale but offset that with tax savings and still come out ahead but get rid of the albatross.

A few ways I have seen to get around this is to use the BRRR strategy with a company like Pine Finacail taking the temporary financing and then refinancing later when your forced appreciation meets more traditional guidelines.
