What is my minimum down payment required?

If you have debt, try to pay more than the minimum payment - even a small amount can have an impact.Don't close any credit card accounts - part of your score involves how much credit is available to you.   

The BRRRR strategy is usually used to get your initial investment back but it is necessary to purchase the property with equity built in, otherwise, the typical low down payment house would take around 5 years to reach the 20% equity mark.I would recommend reaching out to @Amber Gonion and her husband Rick. 

Do I just pay off to the bank after I receive the payment from buyer?

We currently have no money saved for a down-payment on a new place, so we'd like to research if taking equity out of our current home while continuing to rent it out is a feasible strategy to get us in a new place in Rochester.

You  CAN borrow non-recourse funds (there is a list that float around here of providers for those) that typically require 35-50% down payment.

The plan currently is to fund this flip (price at foreclosure sale + reno) by private money at a 10% interest rate with no payments until closing, after the flip.I looked through all the contracts available here on BP and none of them seemed like the right fit. 

The seller is willing to carry a note for the 5% and accept monthly payments until it’s paid off.

The balance would actually be $180k broken down and was/will be used for the following:25k - down payment on previous rental acquisition25k - refurbish our home - already spent50k - consumer debt (both cars and $15k in CC debt)80k - new primary residence down payment We'd actually cash flow $1,000 more a month with consolidating debt.Is interest only HELOC worth it?

To overcome the lack of financials without going to a private lender for the down payment and closing costs, I plan on wholesaling.
