Keep rental income or sell?

[Jim Halpert]

Reaching out to find advice for my best course of action. 

I have a duplex I renovated and have both sides occupied. After I pay my mortgage I bring in 1400$ a month . I’m currently renting myself because of well the crazy housing market . I really want to get my own home to live in and renovate some to have a “home base “ . 

Should I continue to collect rent and try to secure a secondary/vacation home loan. Or sell the duplex and use the profit to purchase .. ?
