You could locate your office in your living place if you can close it off and have a minimum of distractions, especially if they are  personal.Try to maintain control of the things you are responsible for.  

Additionally, since you aren't living in Mexico you may have to consider additional cost of a management company that will take care of renting, cleaning and maintaining the property.

He agreed but only if i would also purchase a second house which was not in as great an area but was structurally much better maintained for another 70K to which I also agreed Now i didn't have the cash necessary to buy both houses but I agreed anyways thinking "If I've got the deals the money will find me".
