Could we still make it worthwhile for the investor if they put up the full deposit?

I have paid sellers a deposit and they carry back a mortgage for me for 5 years, at 6% interest only.  

I now know that she is responsible.I will be sending her the disposition of deposit but am not sure about the actual cost of repairing damages to the bedroom.

Wherever you are getting your loan or mortgage from will review your bank records for the last 2 months and money deposited in those two months will need to be verified, gifts do not count as a valid source.

In between tenants, you may ned to go out there to property assess the condition of the place to refund the securty deposit, but you can do it yourself if you are knowledgable about the laws, etc. 

Some put a cap on the amount of security deposit you can collect and whether or not you can collect last month's rent.One reason we don't collect last month's rent has to do with the confusion it causes when it is indeed time for the tenant to move-out.

Also since we are demoing the interior, we offered his full deposit, should he leave in time, and an extra $1500 if he was out in 30 days.

And if they really earn that much, they should be able to put down an extra month's security deposit (if your state allows this) to cover for the bad credit.

Arrange for a final walk-through with them once the unit is vacated before returning any security deposit;   4.
