Viewing a property next week, as usual checked sale history on RM, it showed no sale history recorded. However spotted a different EA sign outside the house on Streetview.
I don’t usually bother with Zoopla but did a check, and low and behold the property sold 2 years ago for 55 grand less than current asking price.
Further digging (checking out the previous EA listing) show it was sold via online auction.
I’m hoping the listing wasn’t manipulated in some way and it was an admin error, but will definitely not be taking RM info at face value anymore.
