There's obviously opportunity here to build this out and turn it into a basement apartment, which I think would cash flow because of course there's no mortgage. 

These LOCs are typically interest only and adjustable rate, which of course is planned for, again with the equity and the cash flow of the investment, it shouldnt be a problem to at the very least break even, even in the worst of scenarios.

Wondering if anyone knows a software that does that or is our only course manually pay remitted taxes…

There are many cost segregation specialists to choose from, so it’s important to perform due diligence.

Of course, my focus is veterans so I may be biased. 

(and money of course, but that can come from these things)

That has informed us for this year's trip, and we'll be staying in Langosta/Tamarindo, Potrero/Flamingo, and Hermosa (Guanacaste not Jaco).Of course, there are tons of beautiful places in CR, and the better climate (read: less hot) is found at higher elevations. 

They typically provide education and also have classes/courses to take.

I know of some folks in KC and Memphis doing new builds like this, but they are doing it within a much larger and long-term project that includes upwards of 300-500 units built over the course of 5-10 years.Assuming you're looking in Columbia, do you have a "B+/C" neighborhood in mind?

And of course other states are following suit..
