I personally used business credit cards to BRRRR a deal—no money came out of my pocket.

It is DSCR based and no personal tax returns are required to qualify.

I mean I got financially wiped out personally..

The offer is still typically (100% of my transactions since August 17th last year) asking for my buyer agent commission to be paid in the agreement..

Almost like being paid to live there. 

Quote from @Jeffrey Duck: I see no reason to pay an attorney for this, but it's your dime.The current lease was between you and Person B.

They specialized in concrete tilt up, but did a lot of time and materials work for a self made real estate tycoon who owned a lot of Federal Way.Along the way I got my CPA license and practiced in several differing sectors including doing some work with low income housing projects.As far as my start in RE, it was with buying my first personal SFR and later moving to a new residence. 

the property tenants paid for my wife's new car that we needed.

ALL closing costs will be paid by the cash buyer.

With some more math, you’ll see that the extra amount in dollars is not that much compared to the total amount of interest paid.
