Second, go through the list of third parties who will buy your lease, plug-in the VIN as if you own it, see how much anyone will actually pay for it. This will help you to establish a trade-in value.
The challenge with HMF is they are impossibly slow to process a lease buy-out. Very few third parties want to buy out their leases. You may need to buy it yourself first (and pay any sales tax) for someone to buy it.
