Rookie question: keep renting or sell

[Kathleen Albert]

I never set out to be a landlord, but I am. I bought a foreclosure for $285k in 2009. No mortgage, HOA $630/mo. Annual prop taxes $5500. I moved from here about 6 months ago. Renters pay $3850/mo.

I could net $850k+ right now if we sold. I do not plan on moving back to this property. After expenses we net $32k/year - so that's a 11% on ROI and 4% ROE. (BTW just learned concept of ROE, like I said not a professional yet). Note: rental prices and house valuation has not increased in the last 2 years.

Would you sell to get all that $ out?  I feel like a 4% return is quite low.
