Why Market Language Matters Before You Make a Move
Real estate listings, agent reports, and news headlines share a common problem: they assume you already speak the language. Terms like absorption rate, months of supply, and price-to-list ratio appear constantly in market commentary — yet rarely come with definitions. That gap leaves buyers, sellers, and renters making decisions based on an incomplete picture.
This glossary closes that gap. Whether you're tracking neighborhood trends, evaluating an offer strategy, or simply trying to make sense of a monthly housing report, these definitions give you a working vocabulary for understanding what the data actually signals. For a broader foundation, see our beginner's roadmap to the U.S. housing market.
| Balanced Market Benchmark | ~6 months of supply (Widely used industry convention) |
| Metric Type for Pending Sales | Leading indicator (Reflects signed contracts before closing) |
| List-to-Sale Ratio in Hot Markets | Often exceeds 100% (Indicates multiple-offer conditions) |
| Primary Use of Comps | Establishing market value (Used by appraisers and agents) |
| DOM Tracking Scope | Single listing or cumulative (Cumulative DOM spans relisted periods) |
Core Market Metrics — Defined
The terms below appear most frequently in housing reports, MLS dashboards, and real estate news. Knowing them by heart puts you in a stronger position at every stage of a transaction.
Absorption Rate
The pace at which available homes are sold in a given market during a set period, usually one month. A high absorption rate signals strong demand; a low rate suggests homes are sitting longer. Calculated by dividing the number of homes sold by the total homes available.
Months of Supply
How long the current inventory of homes would last if no new listings were added and the sales pace stayed constant. Conventionally, six months is considered a balanced market; below that favors sellers, above it favors buyers.
Days on Market (DOM)
The number of days a listing has been active before going under contract. A falling DOM typically indicates rising demand. Cumulative DOM tracks the total time a property has been listed, even across relisted periods.
List-to-Sale Price Ratio
The final sale price divided by the original asking price, expressed as a percentage. A ratio above 100% means the home sold for more than list price — common in competitive markets. Below 100% indicates buyer negotiating leverage.
Median Sale Price
The middle value of all home sale prices in a given area and period — 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.
Active Inventory
The total number of homes currently listed for sale in a given market. Rising inventory typically gives buyers more options and negotiating room; falling inventory usually tightens competition and can push prices upward.
Pending Sales
Listings that have an accepted offer but have not yet closed. Pending sales are a leading indicator of market activity — rising pending counts often signal stronger closed-sale numbers in the weeks ahead.
Price per Square Foot
A property's sale price divided by its total finished square footage. Useful for comparing similarly sized homes in the same neighborhood, though it should be paired with condition and location factors to be meaningful.
Seller's Market
A market condition in which demand from buyers exceeds the available supply of homes, giving sellers pricing and negotiating power. Characterized by low inventory, short DOM, and frequent offers above asking price.
Buyer's Market
A condition in which housing supply outpaces buyer demand, giving purchasers more negotiating leverage. Buyers can typically negotiate on price, closing costs, and contingencies when this condition holds.
Comparable Sales (Comps)
Recently sold properties that are similar in size, condition, location, and features to the home being evaluated. Appraisers and agents use comps to establish a defensible estimate of a property's current market value.
Curtailment Period
The time between a listing's price reduction and its next sale, used in some market analyses to measure how sellers respond to buyer pushback. A shortening curtailment period can signal sellers becoming more flexible.
Once you're comfortable with these definitions, the next step is learning how to apply them together. Our guide on reading a housing market report walks through exactly that process.
How These Terms Connect to Real Decisions
Glossary terms are most useful when you understand how they relate to each other. Consider a few practical relationships:
- Absorption rate and months of supply move together. A low absorption rate means homes are selling slowly; high months of supply confirms it — both signal a buyer's market where negotiating room typically widens.
- Days on market and list-to-sale ratio together reveal pricing pressure. When DOM rises while list-to-sale ratios fall below 100%, sellers are consistently accepting less than asking — a meaningful signal for offer strategy.
- Median sale price vs. median list price can diverge sharply in fast-moving markets. Tracking both helps you gauge whether published asking prices are realistic.
