Let’s say she gets to the bank once per week. When renters’ checks for security deposits and/or monthly rent arrive, she can post them to the clearing account individually. It will function almost like QuickBooks’ Undeposited Funds account would - as a temporary place to hold the funds until she goes to the bank.
In order to ensure that reconciling her bank account in Quicken to the bank statement goes well, I set up a clearing account (bank type account) for her. Although I favor QuickBooks, the client has her reasons for using Quicken, and it’s her business. I recently did some consulting for a client who uses Quicken for her rental property management business.
