San Antonio Southside Room Rental

[Matthew Perry]

I recently purchased my first investment in the southwest side of San Antonio. I am working with a contractor who has been active in this market for over 10 years and is encouraging me to rent the property by the rooms after the rehab is completed. I had never heard of renting a property by the room outside of university systems and would like to know if anyone has experience with this and what criteria they used to chose this over traditional property renting. The house is a 3/1 with a detached 2 car garage that also has a medium sized enclosed room that was rented out by the previous owner. There is no water, kitchen, or bathroom in the garage room. All 4 rooms would share the one bathroom in the main house (which is my major concern).  

What do I need to know to make a safe, fair, and profitable decision???
