What Signals Indicate Property Growth

The measures that tend to move before prices do, where to find each one, and how to tell a trend that is starting from one that is ending.

Leading and lagging signals

Some measures move before prices; others confirm what has already happened. Permits, job growth and time on market tend to lead. Median sale prices and assessed values lag.

Watching both tells you whether a move is starting or ending. Rising leading indicators with flat prices can mean an opportunity; weakening leading indicators with prices still climbing is a warning.

Days on market

When homes sell faster, buyers are competing. A falling median days on market, especially alongside fewer price reductions, often comes before price gains.

Compare an area with its own history and with its metro. What counts as fast in one market is slow in another. Listing portals and local MLS reports publish this monthly.

Inventory and months of supply

Months of supply is the number of active listings divided by monthly sales: how long it would take to sell everything on the market at the current pace.

As a rough guide, under about six months favors sellers and prices tend to rise; well above six favors buyers. Inventory climbing while sales hold steady is often the first sign a market is cooling.

Building permits

Renovation permits show owners investing in existing homes. New-construction permits show developers' confidence, and also future competing supply.

A sharp rise in renovation permits in an older neighborhood is one of the clearer early signs of change. Most cities publish permit data, and the Census Bureau's Building Permits Survey covers new residential construction by county and metro.

Employment growth

Jobs are the main driver of housing demand. The Bureau of Labor Statistics publishes monthly employment figures for metro areas.

Look at growth over several years and at which industries are adding jobs. A metro growing across several sectors is more durable than one that depends on a single large employer.

Rents

Rising rents raise the value of rental property directly and push some renters toward buying. Zillow's Observed Rent Index tracks typical market rents.

When rents rise faster than prices, yields improve and investor demand usually follows. When prices outrun rents for a long stretch, yields thin out and the market depends more on appreciation continuing.

Momentum in prices themselves

Home prices tend to trend. A market that has risen for several months is more likely to keep rising than to reverse at once, and turning points usually show up first as gains that slow down.

This is why nort.estate's projection damps the recent trend rather than extending it in a straight line. When we tested straight-line extrapolation on historical data it overshot badly at turning points, and did worse than simply assuming prices stay flat.
