make your EM as big as you can.. that can help
As Jay mentioned increasing Due Diligence or EM makes you stand out. Just remember you might lose it if deals falls thru.
Another tactic I've seen in hot markets is make an "As is offer"
All options are a bit of a gamble for a buyer but all are common in a hot market..
Thanks, Jay! Other offer fell through. Added 15k EM. Fingers crossed
