Should I buy the house I am renting from my parents?

[Tony Doland]

I am new to real estate and BP. I am looking to make my first purchase. Currently, I am renting my parents house in the Oklahoma City area. They are not making money off of us we are just paying their mortgage. I have no debt and 15k to work with. (not enough for 20% down on what I am looking to buy) My question is should I buy my parents house, putting 3.5% down, live in it for a year or two then rent it out when we move? 

Is that a good way for me to get into my first house? 

Thank you in advance.
