Adding rental properties

[Elmer Wayne Fisher]

I currently own an SFR for a little over 2 yrs now. My question is what is the best way to use the equity to go buy another property? And how long do you build value in my first home before buying another property? Reason I ask is there is another property local here that I would love to buy if the numbers present themselves feasible.
   I’m looking to move to Florida in another year from now so I also need to consider those circumstances as well. Any suggestions?
