Michelle,In the NYC market, i think our best search resource is Streeteasy, it's the most up to date and provides the most accurate historical sales data. 

My purpose for the HELOC is to get into a property without having a home sale contingency to increase my odds of the offer getting accepted.

@Dominick Tonnarini, The only issue with your plan is that you will have to pay a sizable tax on the sale of that property when you do sell. 

And they might have had a rolling discount from increase % caps. 

We would manage the sale as well (with realtor friend).

I saw that the house was for sale initially, but I wasn't willing to pay the asking price. 

One is for homeowners who are in default and upside down; one is for homeowners who are in default but still have equity in their home; and one is for homeowners who have received Notice of Trustee Sale and their house is about to be foreclosed. 

:)  Wholesaling is definitely hard work, so if that is the route you want to go with your real estate goals know you will have to hustle to find the property, negotiate the contract for it, market the proprety for sale, find a buyer, and assign the contract.
