The amount of cash flow on a home will of course be contingent on the down payment.

Perhaps we "buy" the house from them for the $328K balance to satisfy the lender and don't need a large down payment and then have a separate contract with them to pay $x per month until we've paid the full $172K amount.

One has no mortgage, their other has a HELOC for around $20k remaining and is coming to its 10year term that was established before placing with LLC.My predicament is how/best way to pull equity out of either property for a down payment for the 3 family that is valued around $450k.

Quote from @Jordan Kaylor: I'm new to real estate investing and have secured a HELOC on my existing home.  

I had a heart-to-heart with the contractor and made it clear what our expectations were and no more money (he was asking for a second payment of a three payment contract) would come his way. 

It takes a lot of energy to thoroughly vet a deal and a borrower to make sure financing is secure.

These programs offer options for less money down and in some cases DPA - Down payment assistance.As a banker for over 18+ years I am very skeptical when I hear a new name in the business only because its become tougher to lend with all of the new laws and credit/insurance requirements and regulations.  

I've never heard of a lender that wouldn't count Section 8 payments as income.

Do you already have your next down payment ready and lender ready? 

The deduction is optimized as values increase and can potentially offset the entire net investment (including down payment) for high wage earners.
