There is a solution tailor made for you coming this fall.

I kind of made the Carleton Sheets comment as a joke, but making a point that I was already pursuing real estate at 16. 

Thanks for reading if you made it this far!

They have made me write a lot of explanation letters.

If so, get whatever you agree to in writing, and make sure the language is clear that your payment ends all obligations of your lease and that they cannot come after you for anything after payment is made.

This is my first time venturing into a short sale where I made an all cash offer to purchase a property back in April of this year.  

These aren't necessarily agents associated with that property, but you can see on that page how many recent transactions they've had and a customer rating, and click through to their agent biography. 

We did a complete rehab on a single family and it made sense to add central air.

You may want to see if you can charge tenants for water/sewer so they are made responsible for their usage.  

For example, I can work from anywhere and have customers in Texas, so in theory I could (and would) spend half my time there if it meant the ability to start things in real estate.
