I don't know if most/any of your improvements are going to raise your rents, but they will certainly make your units easier to rent and more likely to maintain higher quality tenants.

My understanding is you live in your primary home and rent the other unit, just looking at your housing situation I don't see a need for LLC, since you live and maintain the home. 

Gene it sounds like the lease was not set up optimally when originally created.A commercial real estate attorney familiar with retail and business litigation should be able to properly evaluate the situation and make recommendations.Does the tenant per the lease have to disclose sales,business financials, and ongoing personal?

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.
