The Market Action Index (MAI) is a market indicator developed by Altos Research that compares the current rate of home sales with the amount of available inventory. In simple terms, it helps show whether buyer demand or housing supply currently has more influence on the market. Altos uses 30 as its buyer/seller benchmark: an index above 30 generally indicates seller-favored conditions, while an index below 30 indicates conditions that are more favorable to buyers. The direction of the index is important too—an increasing MAI can indicate strengthening demand relative to supply, while a declining index may signal that the market is cooling.

At its core, a buyer's or seller's market is determined by the relationship between housing supply and buyer demand. A seller's market occurs when there are relatively few homes available compared with the number of buyers competing for them. Homes may sell more quickly, sellers may have stronger negotiating leverage, and multiple offers can become more common. A buyer's market occurs when available homes outnumber or outpace buyer demand, giving buyers more choices and often greater negotiating power. Other useful indicators include inventory, pace of sales, days on market, price reductions, and how closely homes are selling to their asking prices.

Real estate is inherently local because every community has its own combination of housing supply, buyer demand, property types, price ranges, employment patterns, new construction, lifestyle factors, and available inventory. Fannie Mae defines a property's market area as the geographic region from which most buyer demand comes and where most competing properties are located. That means even nearby properties can appeal to different groups of buyers, and market conditions in Salt Lake City may look very different from Park City, Cedar City, St. George, or Kanab at the same point in time. This is why statewide statistics are useful for understanding broad trends, but local market data is more meaningful when making decisions about a specific property.

Housing market conditions are constantly evolving as new homes are listed, properties go under contract, sales close, prices change, and buyers enter or leave the market. Some indicators can move from week to week. Altos Research, for example, publishes market reports using weekly housing data so changes in inventory, pricing, days on market, and buyer/seller conditions can be identified relatively quickly. Lofty's Market Snapshot also evaluates recent MLS activity and compares statistics from the previous 30 and 60 days to help illustrate how local conditions may be changing. For homeowners considering a sale, this is why market information from several months ago may not accurately reflect today's competitive environment.

No. A rising median sales price does not mean that every home in that market increased by the same percentage. The median price simply represents the midpoint of the homes that sold during a particular period, half sold for more and half sold for less. The number can also change because the mix of homes being sold changes. For example, if a greater proportion of higher-priced homes sells during one period, the median can rise even if individual property values have not increased at the same rate. Your home's value depends on factors such as its location, condition, features, comparable sales, competition, and the demand for properties like yours.

No single statistic tells the entire story. If you're considering selling, several indicators are particularly useful when viewed together: available inventory, months of housing supply, days on market, recent comparable sales, median sale and list prices, sale-to-list-price ratios, price reductions, pending sales, and the pace at which listings are being absorbed by buyers. Fannie Mae's market-condition analysis specifically examines comparable sales, active listings, absorption rate, housing supply, days on market, prices, and sale-to-list ratios when evaluating market trends. Altos Research also tracks inventory, days on market, price changes, and its Market Action Index. Together, these indicators can help show both where the market has been and where conditions may be moving.

For a homeowner, however, the most important question is not simply “How is the Utah market doing?” It is “How is the market performing for homes like mine, in my community and price range?” That is where local market analysis becomes particularly valuable.
