Nancy, I have checked the link and per Colorado law, I am ok to "co-mingle" the funds. I have checked a similar page in the past, but thank you for another good source of info!
In regards, thought, to my original question. The answers above don't solve my problem.
Tenant A-- did not clean the apartment, so she was charged a 75$ penalty for not cleaning the apartment. That is on top of the fee that I have to pay someone to do the cleaning. This is part of her lease and is perfectly legal practice here in Colorado. So Tenant A's SD was 1200. But I only repayed them 1125 (1200-75.) I can handle writing that up in QuickBooks.
But my question is how do I handle writing up Tenant B.
I have a signed Security Deposit agreement from her that includes an addendum that states she will clean the house for a credit of 75$. So she gave me 1675$. But when she moves out she will expect $1750.
Since my security deposit is co-mingled with my rents in one account. I can't just add journal entries or credits, because I need the account to reconcile. So, how do I best handle this?
