Need help with the rental property calculator

[Evangeline O'Dowd]

I'm trying to determine if I should sell any/all of my rental properties in my area and invest somewhere else. Question: when using the rental property calculator, should I put in the current income/expenses or use the income/expenses in the year that I bought the property.  I've had some of them for several years and they've really increased in value.  Thanks for your help!
