You are correct about zillow and bogus listings, it’s completely worthless for that purpose. Redfin has the best map and immrls is the most accurate. I did see a closed sale for the same exact square feet a few streets away on Fox Rd for 365k from two months ago
Consider yourself lucky or smart, almost all of the sales in crowne over the last three months have been in the 300’s, and they are trending downwards into the low 3’s as the more recent they are. Almost all of the listings are in the 3’s, look for closings in september to be primarily $100 a square, the bigger ones are already there.
The sub 3000 sq fters are asking closer to $135 a square, when gas hits $4.50 in July and August, we will see another 10% chunk come out of the local market. I only toured some of the models when they were building crown hill and can’t remember which ones were built by KB, but those were built rather cheaply and should be worth less than the others up there.
