So sorry for your frustration. If you'd like to be set up for an auto search of only 3 car and larger garages, I'd be happy to do that for you. The information sent from our local MLS is more accurate. You will get new listings and price changes the same day they happen. I think some search engines are broader so you get the smaller garages included.
If you'd like auto emails just forward to me what you're looking for besides a 3 car garage, location and price range.
You can contact me at firstname.lastname@example.org.
Have a great weekend
