When I did a lease up several years ago, we had drawings each month after move-in for nice prizes. We offered free application fees (if they were approved, we applied it to their first month's rent.
Lower security deposits for those who qualified ($99 deposit).
You just have to get them excited about it. If they see you excited, it's contagious.
Have Lots of "Open Houses." If they come, look, love it, they lease it when they are ready.
Have a model that is over the top with stuff. Use the prizes as props. For example.
A TV with an XBox. Put signs on the them "Win this in January" or "Win this in February."
A friend of mine is having a "wine walk." It includes wine, cheese, crackers and tours of the community. It's getting popular!
Good Luck!!! Let us know what ideas you use that are successful.
