Keep in mind that most residential mortgages are conforming loans that are resold on the secondary market and bundled into mortgage backed securities.

Or if they already sold it on the secondary market, still, what could be the reason for this having been added into the fine print?

Enodo (Multi-Family investors, developers and asset managers) its just math 6.

Therefore, the math can't be done.

Slowly build out a repeatable process...if you continue to change things (as in different types of properties, different levels of renovation, different finish material, different neighborhoods, etc.) you create more variables and make it harder to solve to the problem.I am a math guy and less unknowns/variables you have the easier the problem will be to solve. 

As a creative professional historically "allergic to math," I never thought I'd consider real estate investing, but life is full of surprises!

Per door does not change the numbers but makes it easier to do napkin math and for people to grasp.

Folks have a hard time with Math..

On that scale we have a range of properties in our portfolio, even though I have started to trade out properties from the lower end back in 2014/2015, and some cashflow a little better - however, when you look at the total financial picture there is a lot more than cash flow: obviously appreciation, but also principal pay down, turn over rate and soft factors like tenant quality and with that turnover cost.RE's primary superpower is equity, cash flow is secondary.

Lastly, looking to buy a commercial real estate deal either self storage or a mix use building in a secondary market with 6 cap and around $5m purchase range.
