<em>Can?t imagine there being that many individual bidders capable of producing a cashiers check north of $1M, is that why the banks are the winning bidders? </em>
A related story:
I am a fisherman. I've always loved it. (The pasttime is not too different from Real Estate, actually.) My grandparents used to take us grandkids out to Lake Cuyamaca in "the Vehicle" and go RV camping during Summers when school was out. We were free to do just about anything we wanted as long as we were within shouting distance of the campsite. While my brothers would chase squirrels, rabbits, frogs and snakes, I would fish. I fished from the shoreline all day long and would only come back when required for meals and sunscreen. I didn't want to miss the chance to catch a nice rainbow trout. I would be out at the water all day long.
My grandfather, Herb (a classic grandfather name, by the way), would by contrast, come out in the morning, spend 30 minutes dropping bait next to mine, and bring a checkers board. Rarely would we get a game in, because he was usually reeling in a fish or helping net one of mine. But he always brought that board.
After a bit he'd head back to "the Vehicle" and read or nap. As a Vice Principal at the local school, he'd certainly earned some rest over summer. He'd show up again at dusk and it always seemed like as soon as he got there, the "bite" would be on.
We would head back and compare notes, and I would be so proud on the days when I happened to bring home a bigger stringer. But those days were rare. He'd spend 1 hour to my 12 and would usually outproduce me. At the time I just thought he was lucky. Maybe he was.
True story.
To answer your question, "Why are the banks 'winning' so often?" Maybe they're lucky, or maybe the old pros know when to fish.
