I meant no offense.
What a bank using NADA thinks it is worth is very different from what I think it is worth (a lot more). I just meant that a bank might value it short at 11k and offer to finance 75% of that, and that the buyer might not be able to come up with the difference.
I lost a deal this week over someone coming up with 2k to refi, so it happens.
Hopefully you're happy with the deal. If it falls through, you might want to post here before relisting on eBay.
