It's wild really, I've been seeing emails from totally trusted sources - credit card bills, bank statements - and people that I have in my contact list go directly to my spam box.
There is so much demand for more housing that a building boom would occur if restrictions were eased. Look at population charts of Texas cities like Austin, San Antonio and Houston where building is easier. Then compare to the relatively flat San Jose and San Francisco population charts.
FTFA: "I negotiated something similar to “I can mention the sale almost immediately after it happens as it will leak regardless; I agree to not disclose the price; you accept that BCC is extraordinarily well-covered on the Internets and that guessing the price will not be that difficult.”"
That's true but the article does mention how most of the things that impact price went in patio11's favor. One can reasonably infer that if the seller feels everything went in his favor at the end of the process that he wasn't bullied too far off of his asking price.
He does also mention how one seller tried to demand a 40% discount at close, and that the broker had a better deal waiting in the wings. So we can have a pretty high degree of certainty that the sale price was between $28,500 and $57,000, likely closer to $57k.
