Dave Ramsey... Should I save for 2nd home or pay off 1st

I just bought my first rental home (with 10% down) where I plan on living in one room the first year while renting the other two out. My question is it more benificial to save up more money to pay for a second home and accumulate more debt or pay off this first one asap?

My plan was to build a housing empire, it'll take a lot longer if I plan on paying each one off before I buy another.
