Sell or keep income producing duplex

[Tiffany Palaskas]

Hi, I currently own a duplex in Puyallup WA. We recently moved to TN and have both sides rented. We profit about $1200 a month from both units. My question is, is it wise for me to sell it and profit $150-200k after owning it for 4.5 years and invest where I currently live? Or should I keep tenants in units and once they move out turn it into midterm rentals for traveling nurses, etc? 

The property is in a great location,  close to stores, restaurants, fair grounds, freeway access, and less than a mile from hospital. Each unit is 3bd/1.75ba, single car garage and fully fenced backyard. 

Any advice would be helpful. We want to build our portfolio. Just trying to see what is the best option. 

Thanks,
