My father in law is a realtor so I have access to MLS. However I believe that there are some public web sites where you can look that up. You will be very surprised that the majority of buyers are mortgaged to the hilt and most are doing near 100% financing. It is astonishing, I would never dream of buying a $1M+ home and not at least putting 40-50% down payment. From my observation looking at Stonebridge, IvyGate, Derby Hill and others, that 75-80% of the buyers have put less 20% down and are carrying $1M+ mortgages. This is a ticking time bomb, wait until all of these mortgages reset or the economy takes a dive.
