@Jeremy Roll I was just discussing this topic with @Josh E.

Then I will be writing a  cease and desist if she continues.

 Given I am a lender and have seen 1000's of rent rolls across the nation, IMO this number will range from 8-12% depending on the factors @John Warren mentioned above.

Sure, they will know the size, the taxes but.... not the utilities, the insurance the rent rolls. 

And so the train continues to roll on down the track....

For example: I wanted to know what homes in a given zip code could cover the cost of a mortgage with a rent roll (based on Zillow’s rent estimate).I’ve been experimenting with many different parameters.I’m no real estate expert but I am a software engineer by trade and I was wondering if the experts here:What would be in your custom real estate report? 

Either way you're hiring contractors, swinging hammers, rolling paint, and remodeling this property.

Even if all I get out of this are true rent rolls and financials, it will be a great practice experience.  

Property is a value-add deal, in which client rolled 1031 funds into this property and will look to develop the property from 6-units to 12-units.

I think I just need an opportunity to get the ball rolling.
