Thank you to the many experts already named on this thread, and many more besides, who respond on a regular basis to the questions asked by new investors!

I preach about this regularly to people looking to invest in Texas and San Antonio ore specifically.

We had jobs there and we took summer classes to lighten the load of the regular semester.

A more likely scenario is you will be a landlord with a tenant, and you will be responsible for the upkeep on the rental as well as your own unit Then when your renter moves out or you evict the renter for non payment of rent you will need to pay to have the unit turned unless you can do this type of work yourself.
