I’ve noticed some similar hijinks near my house. This house sat on the market forever at 450k and was eventually repo’d. I think the auction price listed in the paper was high 300’s or just about 400k. Zillow lists the sale at 109k and now with it’s completely dead landscaping it shows up on the mls for 517,900 how the hell did that happen? Maybe they read the zetimate of 517,899 and figured they’d mark it up a hundred bucks. The house is horrible and couldn’t be on a worse street with am gridlock in your front yard and it’s a hundred yards from a high school. Maybe someone with better access to databases can figure it out.
