As I develop trust and confidence in them, I invest more, and I've come to have a significant portion of my net worth invested with some operators. 

Where is vacancy, maintenance/cap ex, asset protection, PM (include it even if self managing as you deserve to be compensated for your efforts), utilities, misc.  

Single family or multifamily, flips or rentals, new developments in light areas or infill lots?

Are you self managing those properties?

On paper they were amazing deals, in reality they sucked so badly I went into self storage instead.

Without accounting for management fees (I have not yet decided if I will try to self manage), and with planning to raise rents to typical market of $825 for each of the smaller units, and $1200 for the larger unit, does this seem like a worthy first investment? 

For C to B-Larger developments announced nearby-Increased activity in new construction-Building of commercial retail in or near the neighborhood. 

Hopefully it'll be lower, but that where's my urban developers in a few other markets are seeing their numbers come in.

I wanted to share my situation and get some advice.I currently own an apartment in a highly developing area in Guaynabo, PR.

The government of Costa Rica has a policy to limit development and doesn't invest much in infrastructure to bring tourism.
