I currently manage my parents' Condos for short-term renting.

I established a parent LLC that held two subsidiary LLCs—one for the properties in Georgia and Indianapolis and another for those in Alabama.

If so, I'm not sure how you're envisioning qualifying for the parent-child exclusion for property taxes? 

Qualify all student applicants AND THEIR PARENTS OR GUARDIANS before renting. 

Now Grandparents , Parents, and Adult Children all have their own place. 

Cap ex withholding?

I owed 3 months of child support, recently divorced, back home living with parents, driving an old car with over 100k miles and had been recently fired from a job.

How do other members in the community get around you when they are walking on the sidewalk (perhaps in pairs or parents with strollers) especially when there is concomitant traffic and you are not stepping back onto the property / grass / lawn to get out of their way.4.

I'd argue that if you're buying in a high priced market, some inexperienced teenager who lives in his parents basements is even more dangerous to consumers.The fact of the matter is you've got to go to school for 6+ years to be a lawyer or an engineer. 8+ to be a Doctor. 5 year apprenticeship to be an electrician. 

If you don’t have to move out of the parent house recommend since you’re in Texas look at property Tax sales.
