My wife Karolyn and I started Real Estate journey in April 2021 with bigger pockets, and we have since closed on 75 doors, Multifamily and Single Family.

If you are this close to the border or cost you need to purchase through a corporation or through a bank trust (Fideicomiso - Think of this trust to be similar to an inheritance trust or a living family trust in the US.)At all times you are the legal owner of the property, the best way to see it is as a permit or license that allows you to purchase, use, enjoy, rent, renovate, inherit, etc. a property in this zone.
