Property is in a stable area often inhabited by university-affiliated professionals.

Tell the guy where he can stick your security deposit and move on.I'm a veteran myself, and one of the things I love about being a civilian now is how many problems just disappear with the proper application of money. 

Is the property turning into inhabitable ?

I would eventually like to refinance it into non-owner occupied conventional loan but would any banks finance it right now in "non-inhabitable" condition? 

Termite tenting and re-roofing definitely don't take a month.For the roof, you can probably do the work while the tenants inhabit the building.For the termite tenting, you can put your tenants in a hotel for 2-3 nights.

I understand things aren't as strict in the civilian world so it's just a growing pain.

They're nothing that makes the place inhabitable.

The city has an inspector go into the property and do a detailed write-up of all the items needed to make the property inhabitable, It's supposed to be the minimum needed, but some inspectors mention every single thing.

Call the DRE.And as far as doing something verbally with a civilian, imagine standing before the judge and explaining that.
