should i sell my first SFR?

[Benjamin Rogers]

I'm trying to decide whether to sell the first SFR I bought or to continue to rent it.

Purchased at auction in 2017 for $84,500. I have a tenant paying $1,350/month since I've owned it. Market value $175,000. Other houses in the neighborhood are listed for $1,695/month. I've not pushed the rent since I didn't want turnover and my tenant takes good care of the house. 

My thought is to sell and to reinvest the gains, possibly in an opportunity fund to avoid capital gain taxes. 

Any advice?
