Assessing Rental Income Tax For Potential Purchase

[Rachelle Malkoff]

My husband and I are looking at some rental property options in the Boston area and using Net Operating Income (NOI) to assess if the properties would cash-flow based off of downpayment, mortgage rate, rent rate, maintenance, etc. BUT....NOI doesn't include taxes on rental income as a factor in achieving cash-flow even the property comparison spreadsheets I've used don't include rental income taxes.

How did you consider income taxes on cash flow when evaluating the potential of a property?
