they may not know for every single client, but they know in general where it’s coming from.
I have to call BS on this one. How on earth can ANYONE know how many people are out there waiting to buy and what their financial situation is. If they don’t even know their own clients’ financial detail, what make you think they’ll know anything about future buyers.
Your question will NEVER be answered by anyone with any hint of credibility and support their answers by facts. Also, majority of the people who meet your 3 criteria are not the typical buyer of move up areas like NCC.
