Wants to sell this one or all of 4 adjacent parcels occupied with tenants in 7 separate units.  

The conventional lender does care that some or all of the source of the initial funds were a HELOC, and in my experience they will require that the cash proceeds from their loan first go to pay off the amount borrowed on the HELOC to fund the initial purchase.
