Acquiring a Heloc on a property, just prior to sale.

[Kenneth Fite]

My family and I are relocating out of state and are near the end of the process of getting a Heloc on our home specifically for cashflow to cover moving, earnest money, and setup expenses. Our realtors wanted to go ahead and do a trial listing on the house, and we ended up getting a few good offers. The timing of accepting an offer and of the finalization of the Heloc are going to be nearly overlapping.

My question is:   Is there a danger to the sale contract in going ahead with the Heloc just prior to or just after accepting an offer, OR to the new mortgage we would be seeking in the following few months?  Again, the sole purpose is to have cashflow to meet certain deadlines that will likely fall before closing on our current home.
