Those higher paying jobs equate to more mortgages with better terms.

I like the discussion it started.From what I see $100 a door isn't a must but more a variable into an equation and sometimes not even part of the equation.- Depending if you are a cash buyer or financing that variable could be different. - Depending if your goal is monthly cash flow or equity that variable could be different. - Depending on the area of the of the world you are investing in that variable could be different. - Depending on the class type of property that variable could be different.

@Nichole LandowRather than looking at the equation like your losing something, focus on the positive.

@Destiny Prince Personally, I prefer to allocate vacancy of 8%, which equated to roughly one month a year that the unit is vacant.

@Gail Padon  Keep in mind credit score is only one part of the lending equation. 

So you better have various insurance companies there to fight the claim so you don't have to hire your own lawyer.10) If you are mortgaged on the property, your lender will require hazard and liability on the property itself.11)  How many more rentals do you plan to get, as that will figure into the equation and how quickly?

This site is full of new investors who tried to go it alone only to find they've missed key parts of the equations that cost them dearly after the fact. 

If I zero them out or max them, it adjusts the my expenses and the metric.Depreciation/tax and principle pay down are not in the equations.  

I'm using the typical general equation: ARV x .70 -  repair costs = purchase price.I understand the markets are super red hot now however. 

@Anne Williams  A couple of things come into the equation.
