You'll probably be moving a lot the first few years, until you get to your first Fleet squadron. Frequent moves destroy furniture. My personal advice would be to travel light and disposable until then (think Ikea), bank some deployment money, and buy some grownup furniture when you'll be in one place for more than a year. In that vein, also postpone the acquisition of camp followers until then.
In the TRACOM, there are always people with a room to rent. Flight school studs come and go (see above re: frequent moves). You can buy all your bare necessities - bed, dresser, desk, etc, enough to furnish a room - from Amazon or Ikea for well under a G. Fit everything in one mid-size U-Haul or smaller.
If you really want your own place and don't want to buy furniture, the Q in Pensacola has some permanent party (i.e., long term) suites, or at least it did. If you can get into one, it's probably a more sound use of your money than a furnished place in town. Don't let the crazy wait list put you off - a lot of those are people who put their name on the list and then went and got a place out in town. If you follow up every so often (like, once a week or so), you'll probably get a room.
Technique only, though - don't be that guy, the hermit who lives on base. You can be sensible with your pay and still have a social life. Having friends to study and socialize with will make your time in the TRACOM a lot happier, healthier, and more successful.
This is the last time in your life you'll be young, unencumbered, and well-paid. Don't nuke it.
