Depends on the timing, but an over 20% difference is pretty large. If it wasn’t a distressed sale, I’d say, you over bid but maybe just high end of market noise.
As another pointed out, once it’s been on the market and fallen out, unless it’s really mainstream it picks up some taint. People assume it’s wrong, look extra hard to see why it bailed out and bargin twice as hard because it’s old goods.
