How do you track your ROI, etc. for individual properties?

[Curt Hilyer]

My question is specific to properties you already own. My family has a portfolio of around 50 commercial units that have been purchased over the last 20 years or so. I would like to start analyzing these properties to see what our ROI is so we can make more informed decisions about future acquisitions. How are you keeping track of ROI, cash on cash return, cap rate, etc. on your properties? Are you using excel, quickbooks, a property management software (I use AppFolio), or something else? I am very curious to see how other investors are tracking their returns.

Any help is greatly appreciated.
