*Full disclosure - I am a Rent Manager Employee
I would definitely check out our https://www.rentmanager.com/customer-resources/self-help-resources/ including the training videos archive, Knowledgebase, and we recently released a free Year-End Close eBook (http://info.rentmanager.com/year-end-close-ebook). These resources will walk you through a lot of the accounting you are currently doing in Quickbooks and translate it into Rent Manager.
In January, we are also focusing on Accounting and the Year-End Close process. I would encourage your assistant to join our free weekly webinars (Thursdays at 2 PM ET) where she can ask questions related to each topic.
BJY, along with the Year-End Close resources, I believe we have a few loan process resources that might help you. If you are unable to find what you are looking for, our Support Team is great about walking customers through the process on their system. I would definitely give them a call or email them.
