That is kind of how it works when selling a house with a real estate agent.. they only get paid on a sale, and they went to sell as cheap as possible so they get their money.. see https://www.youtube.com/watch?v=17jO_w6f8Ck
That's my point - you don't trust them. And shouldn't trust investment banks who get paid on transactions for coming up with a correct price. (Hence you call McKinsey for the 2nd opinion since they get paid on time rather than transaction.)
Fair enough. Maybe I'm just the cynic. The real estate agent trying to sell my Mom's house came up with a dozen reasons on why it should sell for mid-300s. I did the analysis on the same data and came up with mid-400s. We'll see where it lands.
