Sell or Hold NWI SFR?

[Ryan Vanderlugt]

I purchased a SFR in NWI in 2014 as a primary residence for $120,000 w/ 4.25% 30 yr mortgage. A couple years later we started renting it out for $1200/month. The tenant has been a dream and there have been hardly any issues. The market has appreciated in the area and the house is now worth $150-160k. There is about $90k left on the loan. The tenant has expressed interest in buying it. Should I sell or hold? Due to having to move because of military orders I believe that if I sell it in the next few months I can forego the capital gains in the sale.
