@Adam MatlockHave you asked them why they won't extend insurance to you? 

Not just service animals, but it now extends to emotional support animals via the Fair Housing Amendment Act. 

I suspect that the best solution varies from location to location but for those owners with units near universities, SabbaticalHomes.com is unbeatable for extended stays.

If he loses his job for an extended time are you cool covering the mortgage while he lives there and how long would that be ok?

The high level risks are discovering unplanned repairs, anything that extends your timeline (since a decent part of your budget is holding costs), and problems with contractors.
