Zillow does look different. Don’t know if anyone bought them. I have no idea what algorithm they use… I just checked my house – it’s “zestimate” is very high (inaccurate, IMO). They also show a wierd dip in the last 30 days, then almost instant recovery. That’s true for a couple of my neighbors as well. I think it’s when the house for sale across the street went pending.
As far as rents – we got a big increase in rent with our new tenant a few months ago… but that’s because we no longer are offering “family discount”. (It’s good for the pocketbook to get market rent.) Our rental is unusual so hard to comp to other places…
