Move-in fee v. security deposit

[Joey Nakayama]

As a Chicago landlord, I've noticed many local apartment listings that ask for a non-refundable move-in fee instead of a security deposit. I suspect this is partially due to Chicago's strict laws regarding security deposits.

Fellow landlords, where do you fall on this issue (especially you Chicagoans)?

And for any renters out there who have weighed these options, what do you think?
