so i'm gonna assume your friend is going to rollins, ucf or fullsail judging by winter park area.
rent in the area can be extremely high, but doesn't have to be. there are some very swank areas of winter park, on the chain of lakes and such, but as long as you stay away from those areas to live in, you should be fine. there are multiple large apt complexes along 436 in winter park and casselberry, all of which would be fine for any of those schools, and most of them are pretty reasonably priced. there are also some houses and apts for rent in winter park/orlando behind and around the fashion square mall off of highway 50, but those will probably be a bit more in rent than the others. as far as around ucf and full sail, there are a ton of student housing developments and also plenty of neighborhoods which im sure will have some houses for rent, just drive down university blvd and look - also check out north and south on alafaya tr.
if you have any specific questions, either email or pm me, i can tell you some good hang outs and such if you're up for it, or whatever you might want to know....also talk to psychoandy, i know he's from the orlando area as well.
