After seeing house twice, signing 1 year lease, tenant started moving things in and decides the basement smells "too mildewy" and not liveable.She wants  her 1 month security deposit back.

A bid deposit is typically required for new auction participants.

As a buyer I could be flexible on allowing the seller to stay over with rent and large deposit held in escrow.Why not see if your buyers can be flexible?

You are putting a deposit down for the appropriate governing body to foreclose on the property for delinquent property taxes.

(I plan to do some remodel work in February, so would be looking for new leases to begin in March).2) The current owners are collecting September rent, which will be credited back to me at escrow, along the the 5 security deposits.  

I have to use the entire security deposit to cover lost rent.  

Your IRA would get a deposit each month until you are cashed out and you won't have any management issues--those fall to the owner/landlord.

We have my mom on our bank account so she can collect rents and deposit them for us.  

I have BA and been with chase, BA is great so far, my deposits clear every midnight ( i think i'm special) regardless of amount which doesn't happen in most banks.

These individuals are held to a higher standard, and also have direct deposit available through the government.
