I apologize in advance for the length of the post below...A little background on me; I have a little (mostly negative) experience as a landlord after we, my wife and I, moved out of our first home in late 2010 and looked to renting because, shocker, we were underwater.

I live with my wife in our own home and we both have full time jobs that take up a 12 hours of our day.

Hii everyone, I am from Philly and have done a little real estate here before but making the switch to full time for now.

You should check out the latest BP Podcast with @Steve Garner as he talks about using this method.https://www.biggerpockets.com/renewsblog/bp-podcast-193finding-managing-rental-properties-working-full-time-steve-garner/

You could also complete a full 1031 exchange and then refi to take cash out (You would not want to refi the existing property if you anticipate selling it and doing a 1031 in the next few months).  

BP is full of experienced investors that can help answer questions.
