OK, so I think we can all agree: bidding wars ARE THE WORST. You get all crazy emotional, and start laying awake at night picturing your new life between your new walls, and come up with your highest and best offer, and then someone swoops in all WHEE I HAVE SO MUCH MONEYYYY and you can't even compete but you try to, and start offering more and more and more, and then don't get it anyway, and:
-> tears.
Anyway, I've been through a few bidding wars over the course of my life as a homeowner (six, to be precise, with another one on the horizon this week). I have also been on the other side, as a seller. And what I have learned is that there is nothing you can do to control the outcome (short of having unlimited reserves of cash, in which case that's wonderful and also you are probably reading the wrong website), but there is a whole lot you can do to tip the scales in your favor.
Are any of these things going to for-sure win you the house? No. But they will make it more likely, and "more likely" is better than "less likely," am I right?
