Why is it a benchmark of "accuracy" for an AVM compared to the SALE PRICE?Dude - that was a lifetime ago WRT valuation technology. I remember back in the day doing an analysis of AVM's and their accuracy. We compared AVM values to some 5,000 home sales across the US - the accuracy rate then (circa 2010 +/-) was around 80%. I'd hazard now that most of them are better than 95%. The key for the folks trying to figure out how to lean on AVM's even more in their risk management roles is trying to figure out how they can determine which homes the AVM's are gonna be wrong on. And to your point - it's the albatross homes.
To use your home as an example, why would you need an appraisal if you're in a homogeneous market? (and, of course, you have a good idea of property condition - which you get with the PDC)
You never did say whether you think Zillow (or Redfin) is accurate for your place?
Appraisers are opining market value, not sale price. It is a closed loop to use AVMs based on sale prices and then judge them by how close their result is to the sale price !
