First I have heard of Monetized Investment Sales.  

If the Self-Sufficiency Rental Income is less than your PITI, then the resulting decimal will be less than 1.Examples (fictional numbers to demonstrate):Net Self-Sufficiency Rental Income < PITIPITI = $1000/moNet Self-Sufficiency Rental Income = $500/moPITI / Net Self-Sufficiency Rental Income = 1000 / 500 = 2.0 = 200% (Not Allowed)Net Self-Sufficiency Rental Income > PITIPITI = $1000/moNet Self-Sufficiency Rental Income = $1500/moPITI / Net Self-Sufficiency Rental Income = 1000 / 1500 = 0.67 = 67% (Allowed)Which in a nutshell says that the rent that you receive on the other 3 units, cannot exceed the total payment on your mortgage.

Housing can be a very emotional decision and as investors we monetize our tenants' need for housing. 

If someone wants my direct involvement educating them then that time has to be monetized for myself.

I make $2000/mo net cash flow from my first house hack, which started as a 203k. 

It's very common for companies to introduce new product, have it all free until they get good market share, then start monetizing it.

Even with that reputation, we have found it very difficult to monetize the open house.

Dig deeper and talk to management companies, and see how long tenants tend to stick around in the specific segments of the market that you think would work best.Remember- if you research and base your decisions off of what every other investor on this forum does, you're going to end up banging your head against the wall trying to monetize concepts that have been wrung dry by the masses.

When they realize they can cut their rent payments significantly if they have a means to monetize their rented property, they will. 

This will elevate your stature as a professional and open up a lot more opportunities for you to monetize deals you can’t buy or wholesale.
