I am going to show you how to look at a Zillow listing and decide if the property is cashflow positive or negative. Obviously, I want you to dig into these numbers and verify the rent and expense numbers, but start with just the basic calculation. If the numbers don't work on the initial calculation, then it is not worth your time. If the numbers do work, it is time to move into due diligence and verify the rental and expense amounts. FYI in this hot market, most listing don't work. That is why it is up to you to always look at the new listings and run the numbers daily.
