All deposit funds and first (last ?) months rent , you should refuse personal check and only accept cash or cashiers check bought at YOUR bank . No money orders either. Cash cannot bounce , later on if you accept checks for rent so be it again cash cannot bounce. Minor children do not need to be listed on the lease , you can list the adults names and write in >five minor children x number male x number female, You can also request month and year each was born in a application. (if they stay on a long time )The reason would be later on but well before the older teens birthdays you could simply go see them in person and make a copy of the 18 yr olds ID and SS card on the spot , ( yes bring a copier that can run off a inverter plugged into your car ) the reason for this would be that at some point if the parents decided to move but now grown Suzie refuses to move with mom and dad and stays behind moving her signifigant other Spawnof Satan in , you will already have her ID information making it abit easier to evict. BTW the police dept that served the applicants last known address might be able to tell you if there were any police call records for the tenants last known address, It wont tell you if they were angels but alot of calls during the tenancy will signal a bit more research.
