The one across the street is a model match and has been sitting for 174 days, so 449k is probably not the right price. Once again comparing things to what others are not selling at isn’t a very good way to arrive at a price.
Compared to the one for auction but looking at the sattelite photo the auction house has absolutely no backyard and probably isn’t in that great of condition. The one at 449 does have a bit more yard.
