First triplex need some advice

[Memi Lee]

Hi everyone I just purchased my first triplex in Ohio, I'm needing to find out if I can collect past due rents since I just acquired the property Feb 1st. Two of the three are behind. In addition where to find new leasing agreement. Also the tenants have asked about their security deposit which the previous owner denies having. what's the best way to handle these situations.

Thanks in advance.
