I have a couple of questions:
1. What is the market value if you chose to sell?
2. What is the loan balance roughly?
3. How did you come up with $1500 as fair rent?
4. What the heck are you doing in Oklahoma, it must be brutal living in the bible belt and being gay (I’m only assuming that becuase domestic partner is rarely used in lieu of girlfriend/boyfriend).
5. Do you have the cash and income to qualify for a second purchase down the road and being able to carry both houses with reserves if there is a gap in renters.
My advice without knowing the answers, live where you and your partner are happy, have a management company handle the rental and just rent somewhere because you have a job that is subject to moving you great distances. Get to one of the coasts where nobody cares what your orientation or living situation is.
