These rates can get very high, but access to more lending unsecured if needed. 

You’d probably end up with a bigger after tax gain if you sold the 2nd property for any amount of money and did that.

Buy low sell high..

End of story. 

Zillow is saying the house is worth $90k but recently a tree went through the back end of it and I was hoping to get some information on possible ideas or suggestions on what I should do about the situation.

Real estate agents are not highly regulated in Costa Rica as opposed to North America.  

My end goal is change the lives of others one property at a time and I am hoping this group will help me do just that. 

Maintenance and admins fees are high.

I strongly suggest you stop, and get a team around you, or it will not end well. 

That way, there is some type of cushion to help against any high usage months, should they just happen to use more than your previous tenants did, or if you unfortunately get tenants who abuse the "utilities included" opportunity.
