Quote from @Emily Gowen: I only recommend investors sell when they can move the money to a better-performing investment or when the sale moves them closer to a specific goal.

Conversely, a new built A class SFR, in A class market of significant growth via a well laid out planned city development, great schools, area people are glamouring to move to, a-class tenants, very very low risk.

Would a cash-out refinance to free up equity and keep growing be a smart move, or should I focus on paying down my existing debts?

If one tenant moves out, the property remains cash-flow positive. 

Courts move super slow.

Welcome to BP Daniel, I did the same move from Seattle down here a few years back! 

Remember, confidence grows with each step, so take action and keep moving forward!

I have done 100s and 100s and 100s there, thousands of move in and outs best part I live in Fl my PM handles it all.

Sharing this idea in case others can comment on it.I agree, the US is more friendly about receiving investments from foreignors.You are planning to move back to Spain?

But if you feel like you can learn the same skills on your own through experience and other resources, saving that extra tuition for your first investment might be the better move.
