One of the better indicators of market activity in the real estate market is the under contract ratio. This ratio shows the relationship between the houses that have found a buyer and are waiting to close and those that are still waiting to find a buyer. The higher the percentage the more activity there is in that particular market segment.
The first two graphs below show the under contract ratio for Boulder, Louisville, Lafayette, Longmont, Boulder County as a whole and Weld County as a whole. The first shows single family homes and the second shows attached dwellings or condos.
The third graph is quite interesting. It shows the under contract ratio across price ranges. This shows very clearly that the activity in the market is in the lower price ranges. Just over 40% of homes listed for under $250,000 are under contract while less than 2% of the homes listed for over $1,250,000 are under contract. 
There are a lot of homes which are yet to be sold in the US. For homes of cheaper rate the demand is high! Many people have booked in advance for such homes! I know of a certain website which promotes real estate business! People can buy and sell homes in the US. Almost any kind of property can be bought and sold. Lot of foreclosure homes are available which are available to be sold!
The graphs are easily understandable. But was it carried out using proper methods? Can it be taken as correct. I checked the website that you mentioned MC and found it to be really helpful with awesome experience.Foreclosures deals can be made and experience will lead to success.
