BPOs flawed, costly
The top producing REO specialist Realtor in my area asked me for some assistance in doing research for her BPOs, which she initially used to try to secure the listing, and afterwards to comply with the asset manager's requirement to provide a new BPO every month on every property listed. Since her personal inventory is in the 100s of listings at any given time, she clearly doesn't have time to do "accurate" BPOs on all of those herself. Her solution was to mark everything declining value, 9+ months marketing, excess inventory, avg condition and location etc. She didn't drive the comps, some of which had remarkably better or worse locations, didn't use nearby comps (hers were usually 1+ mile away when there were 10 within 1/2 mile), had no clue on how to adjust the subject distress sale to the market, clueless about cost-to-cure defects, and had no understanding that a 5-bedroom house in a blue-collar family neighborhood having a carpeted 7'x8' kitchen and dining area and with only 4 kitchen base cabinets was a functional problem which most certainly was a reason the property was still on the market after 635 days. When I brought those issues to her with a realistic listing value 20% below hers, she was furious because she said, "I can't tell my client in Nebraska that!" because she thought she'd lose the listing. It would have been kinder to be straight with that lender back then, using a real appraisal, because it took much more time to sell that property in a downward market, and it probably cost them an additional $300,000 in value losses than if they had hit the nail on the head with an accurate unbiased appraisal in the first place. So they got their "free" BPO, and it only cost them an additional $300,000.
Lenders apparently don't value unbiased accurate information which might enable them to make prudent financial decisions. They'd rather entrust the value to an agent who might be 'bidding' to get or retain the listing. Brainiac financial banking geniuses.
