I'm considering doing this with our primary residence in La Mesa when we move out of the home, but I want to connect with experts in the area who are already doing this.

And Argentina already is a primary source of investment in Paraguay real estate so no need to verify that.

We recently did the same thing with our primary house.

In most places you can only do work requiring a building permit if it is your primary residence or unless you are a licensed and insured contractor. 

We could do it as a primary residence for her if the 1 bedroom side were open. 

It would not work as well, I assume, for my primary home, where my interest rate is 3%.There is a calculator at: https://www.allinoneloan.com/#calculatorThe calculator says it should work well for my investment condo - but I would actually love to hear from others who might have taken out this product and paid off their property much faster as a result!

In the upcoming year, we are getting roommates to help with expenses while continuing occupying as primary residence.

I need money to rehab should i do a heloc on my primary residence ?

I lived in Sugar Land (until 2 weeks ago) and kept my old primary residence as a long term rental.

We would eventually move into the second property and establish it as our primary residence (6-10 years from now).
