Why Housing Jargon Matters
Scroll through any real estate report or housing news story and you'll encounter a thicket of acronyms and data points: DOM, MOI, absorption rate, list-to-sale ratio. For everyday readers, these terms can feel like insider code — and when you can't decode them, it's hard to know what a headline is actually telling you.
This glossary cuts through that noise. Whether you're navigating the homebuying process for the first time or simply trying to follow housing news with more confidence, understanding the vocabulary gives you the foundation to do it.

The Core Terms, Defined
The terms below appear most frequently in housing data, news coverage, and MLS reports. Each one measures something specific — and knowing what that is helps you assess what a market is actually doing.
Days on Market (DOM)
The number of days a listing has been actively available for sale before going under contract. Low DOM typically indicates high demand; high DOM can signal overpricing or weak buyer interest in a given area.
Months of Supply (MOI)
An estimate of how long it would take to sell all current listings at the current sales pace, assuming no new listings are added. Under four months generally favors sellers; over six months generally favors buyers.
Absorption Rate
The rate at which available homes are sold in a specific market over a given period, usually expressed as a percentage. A high absorption rate signals strong demand relative to supply.
List-to-Sale Ratio
The final sale price expressed as a percentage of the original list price. A ratio above 100% means buyers paid more than asking, indicating a competitive market; below 100% means sellers accepted less.
Active Inventory
The total count of homes currently listed for sale in a given market at any point in time. It is distinct from new listings, which measures only homes added during a specific period.
Pending Sales
Homes under contract but not yet closed. Pending sales data is a leading indicator of near-term closed sales volume and reflects current buyer demand.
Median Sale Price
The midpoint sale price in a set of transactions — half sold for more, half for less. Median is preferred over average because it is less distorted by a small number of very high or very low sales.
Price Reduction Rate
The share of active listings that have had at least one price cut. A rising price reduction rate suggests sellers are adjusting expectations downward, often an early sign of softening demand.
Once you're comfortable with these definitions, learn which metrics most reliably signal where a market is headed — not all data points carry equal weight.
How to Apply These Terms to Real Headlines
Knowing definitions is step one. The more useful skill is recognizing how these metrics interact. A low days on market figure and a list-to-sale ratio above 100% together signal a competitive seller's market — homes are moving fast and buyers are bidding over asking. Conversely, rising months of supply and a widening gap between list and sale prices suggest growing buyer leverage.
Context also matters enormously. National averages can mask sharp local divergences — a city with a hot downtown core may have sluggish suburban inventory in the same metro. Before drawing conclusions from any headline, use this checklist to evaluate what a market story actually means for you.
If you're renting and trying to read the market to time a move or a lease renewal, the same principles apply — our renter guidance hub addresses how broader market signals affect tenants specifically.
National Data Isn't Always Local Data
Most housing metrics reported in the news are national or state-level aggregates. Local markets — even neighborhoods within the same city — can behave very differently. When evaluating any data point, check whether it applies to the specific market you care about.
