Rent is due on the first of the month and after the 7th of the month there is a $10 late charge added to your account, after the 20th of the month you unit will be over locked and you will be denied access, after 60 days your unit will be put on the lien sale list.
I have moved out, when do I get my security deposit?
Once we have noticed the lock is off your unit, the unit is cleaned out and broom swept we will process your security deposit. All security deposits are refunded by check and you can expect that within 2 weeks.
