Dr. lala,
First, congratulations on your acceptance to LECOM. You'll get a great education at this school.
As for housing, I too recommend Lakeview. It is fairly new and well-run. The price is excellent too if you have a roommate. I wouldn't say you have to get on the waitlist now, but I would start looking around late April/May. They don't really know who's moving out until a month or so before usually.
DO NOT move into Granada. It's cheap and that's about the only good thing I can say about it. Horrible management, poor facilities, farther from school (than Lakeview)...it can make your first year more miserable than it has to be.
Check out the 1st year student info on lecomsga.com. Also, you'll be receiving a housing packet from admissions. If you're interested in a place, post it here to see if anyone has any info on it.
Good luck,
