I’m not so concerned about them leaving listings active too long.
I’m more concerned with agents who will keep a foreclosure off MLS, find a buyer themselves, then put the listing on MLS for an hour so they can pass the the bank’s sniff test and claim the house was “fairly marketed”. They actually have a term for this…the realtors call it “running it through the MLS”.
I think that is totally disgusting and robs banks, and comparables, of fair market value. This has got to be one of the most damaging and least enforced racket of the year.
