Why didn't you just say that in the first place?
It took you a long way round to state a reasonable point that most everyone here would agree with. No reason to post examples that you don't have all the details for.
Many lots on the market have build out times left that make it impossible to buy now and meet requirements. I was told the one in WS you mentioned is one of them. So what does that make it worth? I don't know but you can't use it to prove your point.
I understand market value. I'm not implying that most properties were not sold for market value.
You pointed out specific selling prices and you can't be certain they were at market value unless you have full knowledge of the transaction.
