Your best bet is to get on the phone, get multiple opinions, multiple quotes, and make decisions on the type of build before pulling the trigger.

Hey guys im looking at real estate in South America ,for the price of a studio here in the U.S there you can get a 3br +1000sqf house in nice area of town ready to move in, been pondering on getting a personal loan here in the U.S to invest in a house in SA, what banks are best for this type of loan, i would like a low interest and monthly payments.

These types of agreements can get a little in-depth, but that is what you want for your protection and that other partner.

To be clear I’ve never done this so I don’t know if you would need a $10,000 or $25,000 or what type of payment.

This is the type of deal where doing your homework upfront pays off big time later.

I agree that DealCheck (or the BP calculator) does not provide enough tools or functionality to analyze those types of transactions (yet).But I would argue that it does a great job at analyzing more traditional buy & hold SFRs and multi-families, as well as flips and rehab projects. 

Things like your vacations, entertainment, toys, food, clothes, housekeeping, pets, guns etc.

It depends on how many guns you want to carry!!
