If I were pay myself, would I simply pull out money from the B account as I see fit, or reasonable pull-outs based on my own calculated profits after tax?

What I do is offfer my angry tennants the opportunity to get into real estate investing, offer them work in maintaining properties, collecting rents, and offer guidance on them being able to buy their first place of their own.Don't you think they would love to have at minimum two jobs to be able to save up the money , work their ends off to build up their credit, hunt down deals, and negotiate a purchase, invest their money knowing there is no guarantee of ever getting your money out of it or of profiting, have to spend thousands of dollars or 10's of thousands of dollars, even hundreds of thousands of dollars in order to be a ble to provide others with housing?

First, the asset starts generating CF after year 1 (but let's assume a few years) due to the depreciation of the loan, so it's not like I'm living with a complete burden.

These folks are typically trying to finance properties that someone like me can't touch, so they squeeze every dime of profit out of it they can.

When dealing with a seller you will need to obtain:-Current Rent Roll-2-3 years of Profit and Loss StatementsThese are the two most basic elements in beginning to "pre underwrite" a loan for multifamily. 

Top agents only work with listings and they are lead generation and closing machines.

Compare that to a potential $4k/year cf, it would take almost 5 years to get the same money you would if you sold (assuming 15% fees/commissions/closing).If you reinvested the profit from the sale, you should be able to still get the same or better cf in a different property.

Hope there was still some profit left after transaction and holding costs.

I have done some rough math and as I pay him back I will still be profiting.

I'm confused though as to how to calculate my gross profit.
