I'm with @Ben Zimmerman on this one,
Not to discourage you or persuade you to do other wise but if you only have $7,000 think about all the expenses you'll occur since it's a flip, do your research and don't consider a low-end estimate.
-Can you afford the mortgage, taxes and all utilities by yourself? Since it's a flip having roommates will be nearly impossible due to the living conditions if you're hacking at walls, gutting bathrooms and so on. This can cause legal issues quickly and they'll probably win...
- Do you have the time? Flipping with a full-time job is rough but doable especially at your age just no that you will probably not need a phone anymore since you wont have a social life haha.
- Do you have friends that are handy because this will help a lot especially if you can bribe them once in a while with pizza and beer.
I can't stress enough on the expenses! If you need appliances, new roof, A/C, tools, new tile or carpet, any other main renovations. While $7,000 looks great at 22 you can spend that on decent A/C.
If you can manage all of this than Do it, if not take an extra year and save for at least $10K just for the flip.
