Key points include:Security Deposits: In Indiana, there’s no legal cap on security deposits, but you must return the deposit (minus any valid deductions) within 45 days of the tenant vacating the property.Evictions: Follow the formal process carefully.

We also received a $2400 security deposit.

You’re not using a PM, AND you’re assuming you can charge a service animal a deposit and pet rent?

The law does NOT apply to landlords:With less then 5 rental unitsThat live in one unit of a duplex and rent out the other unitThat rent out rooms in the home they occupySo, landlords can no longer state in their rental ads, "Section 8 not accepted".The reverse is also true, "Section 8 only", cannot be used.We've always recommended screening S8 tenants the same way as cash-paying tenants.Landlords waiving application fees and/or security deposits only for S8 prospects may also be violating Fair Housing.

  $2500 deposit is put down. 

After searching more, I found a few BP post where people seemed to have one account for all deposits, and keep only deposits in there.

I just had tenants move out of my investment property (duplex) without paying for the last month's rent, and the damage they inflicted onto the property exceeds their security deposit amount.

If you really want to get rid of them, sweeten the pot by offering to return their deposit after you verify the unit is empty with no damages. 

Lenders will want to see those funds deposited in a bank or other lending institution on one or two monthly statements.

No free weeks, no reduced deposit, etc.
