Bookkeeping and Accounting

[Hunter Warren]

Hello! 

It's almost been 1 year since I bought my first property that I've been house hacking here in Fort Collins, CO and I'm planning on buying another one in a couple months, but I am wondering how to keep track of business expenses in an efficient way. I have a business debit card for my current property which makes things easy - every payment/charge on that card belongs to this property. Do I get new credit/debit cards for each property (this option sounds less than ideal)? How would I be able to keep close track of expenses if I just use 1 card for all of the future properties? 

How do you keep track of expenses on multiple properties?
