Black Diamond Market Statistics

For Sale vs. Sold

This graph compares the number of homes currently on the market (for sale) with the number of homes that have recently sold. Together, these two data points reveal how balanced—or competitive—the housing market is at a given time.

When the number of homes for sale is high compared to homes sold, it can indicate a slower market where buyers have more options and negotiating power. When sold homes outpace available listings, it often signals strong demand, increased competition, and upward pressure on prices.

CDOM & Sales Price vs. Sold Price

This graph combines two important indicators of market behavior: Cumulative Days on Market (CDOM) and the relationship between a home’s list price and its final sold price. CDOM shows how long homes are taking to sell, including time from previous listings, while the list-to-sold price comparison reveals how closely prices align with buyer demand.

Together, these metrics provide insight into market momentum and pricing accuracy. Shorter CDOM and sold prices at or above list price typically signal strong demand and a competitive market. Longer CDOM and sold prices below list price may indicate softer conditions, where buyers have more leverage and pricing needs to be more strategic.

A note about statistics:

Real estate statistics are inherently backward-looking—they reflect what has already happened in the market, not what is happening in real time. Data points such as recent sales prices, days on market, inventory levels, and list-to-sale price ratios are based on closed transactions, which typically represent decisions made weeks or even months earlier.

While this means the data doesn’t predict the future with certainty, it is incredibly valuable for understanding where the market currently stands and where it may be heading. By analyzing trends over time—rather than a single data point—we can see shifts in buyer demand, seller confidence, and pricing momentum as they begin to form.
