If you have a gap then then no return of deposit.

I naively gave them their security deposit back without them giving me the keys. 

If they were higher risk, I would charge them a larger deposit.

If need be I can still get out because of a financing contingency and get my deposits back.

- How much of a deposit should I give ? 

Hi Experts,Need your assistance, I have a very good tenant (senior couple), the guy went through some medical condition and he called me to check if I can loan half of security deposit to him just to cover expenses this upcoming month ( Jan'19), he said the rent is on auto-payment and I'll get complete rent but he wanted to see if I can give him half of security deposit to cover his expenses, I never dealt with this before and wanted to see the best way I can help my tenant here. 

@Michelle Shriver, you only need to open an account with $5 minimum deposit to become a member.

When my tenant claimed it needed repaired and admitted one of her kids did it (a towel bar is not a pull-up bar) I told her she could fix it or I could fix it when she moves out (security deposit deduction). 

My involvement was my employees had to take time off the give court depositions on a lawsuit for over $2 million.

Out of those 9, I approved 2 and  moved forward in the application process, both times those individuals bailed within a couple hours of the scheduled deposit to hold meeting.
