Newbie itching to get started

[Andrew Powers]

I currently own a home with my wife and newborn girl. I'm in the military for the next 2 years and would like to started in REI by the time I get out. We have a 3 bed, 2 bath single family home in a decent neighborhood that could easily be converted to a 4 bed. I bought the house at 219k, it is paid down to 205k, and is listed at 240k. Ideally, I would like to add the 4th bed and move into a multifamily for a house hack, but I've only so far been doing research and am still wrapping my head around the finances. Our total debt including the mortgage is ~240k. Income is 60k after childcare. What are your thoughts? Is it too much to keep the house as a rental? Should I sell instead and dive into a house hack?
