$4k interest for 6 months with a principal of $50k is 16% and is a totally different consideration. 

I put a disclosure that I am the principal in the transaction not taking a fee.. and I am buying for PROFIT or LOSS  … they sign and acknowledge that.. and if they want to sell for what I want to pay .. deal is done.if your think your going to tell someone their house is worth X when its really worth Y just so you can make a big spread that is greater than your commission or tell them your not taking a commission.. then that's your choice..Although do keep in mind most wholesale deals are distressed wrecked houses that need rehab etc.. and commission are negotiable.. there is no law of charging a higher commission for tough to sell properties.. if that is what your aiming to do.. 00I worked a builder out of a 22  duplex's he had built was having a tough time selling.. he wanted 30

The savings principal is backed by a solid asset. 

I need help getting a HELOC on my principal residence. 

Your offer is no money down, and pure principal.  

My numbers are based on net return and include principal & interest loan payments, insurance, estimated taxes, utilities (i have to pay them), and property management.

I discovered that it would take us roughly 7.3 years to break even on the 30 year loan, as we will be paying less principal and more interest, but ultimately getting rid of PMI.

I don't think I should count the missed principal payments as cash flow because that is in effect reducing my equity in my property, but what about the interest I would not be paying for those two months?

You didn't provide me with the interest rate so I just assumed interest at 5.140% off of the principal payment you provided.
