As you grow and get more complex, consider something that ties into your accounting software. 

When forcible detainer cases are heard in markets like mine where the 'care act' provided sufficient funds to cover rent for a number of months, I will be very surprised if these cases receive a lot of sympathy from court.

Creditors for future credit applications (such as a mortgage, purchase or refinance) are, and will be, allowed to discriminate on that basis even if there is no FICO impact, just like "declared bankruptcy" or "did not pay court ordered child support" - they can hold those things against you even if you have an 850 FICO score. 

You could also pay for Quickbooks (I don't recommend that yet) for tracking income and expenses.Just keep it simple and add complexity only as you actually discover a need for it.

Below are just a few of the key metrics I look at...there are many, many others: I like to purchase apartment complexes at or near 90% occupancy.

Hopefully they will move out, as the courts are currently closed.
