Net Operating Income (NOI), Monthly Cash Flow, Cap Rate, and Gross Rent Multiplier. This tool should be the first one that you use when evaluating a property. It is designed to give a very quick overview of a property in order to sort out which properties you want to take a closer look at.
The "Property Valuation" section will give you an estimate of what the value is worth based off of the desired cap rate that you enter in the inputs. It will also give a second estimate based on the 2% rule, as well as the average value between the two previous estimates.
