What "books" do you keep for your rental properties?

[Bienes Raices]

Right now I just have Quicken files for the properties, a corporate kit for the one LLC, and Excel spreadsheets where I input the information from my deductible receipts. Is there a better system? Should I be doing things differently? Thanks.

I keep all my records in Quicken as well.

At the end of the year I send my CPA a Quicken report for each property as well as a pdf with all scanned receipts for each property.

I use Quicken anyway for my personal finances, so this was a quick cheap solution for me.
