How do I do my bookeeping for my 3 rental properties

[Jayden Hamilton]

I own 3 rental properties, besides me collecting the monthly rental checks and keeping track of all my receipts that are business expenses, how do I start my bookkeeping for when tax time comes and I have to hand over all the receipts and information. I have no idea how to do bookkeeping, besides signing the lease and collecting the rental check each month, and keeping receipts, I don't know what else to do?
