This is the exact reason why you never collect just one month rent as a security deposit.

I get a security discount on my insurance from my ring cameras that alert on motion.

Always keep marketing the property til the security deposit is received 

Quote from @Maya Jones: You should get something agreed upon for the tenants living and the remaining rent/security deposit if there is something changing from the existing lease. 

Many lenders, including ourselves, will take your past projects into account when offering you better loan terms.If you have a proven track record, we can help you secure even more favorable terms on your next flip.

I had a tenant who had a Surety bond with Assurant for the security deposit, but they are getting out of the business and are not renewing any of their policies. 

Hello,I was wondering for the security deposit return the following:1.

Here’s the approach we took to secure capital without the usual bank delays

Not sure if this belongs here or in Legal, but anyway....I mailed out a returned security deposit (via certified mail), but the former tenant never picked it up/signed for it so it was returned to me. 

Coincidentally the list of repairs they emailed her equals the amount of her security deposit.
