Existing Home Sales Explained

Resales, not new construction, make up the vast majority of the US housing market — and this report is the clearest read on real-world buyer demand.

The bulk of the housing market

Existing Home Sales, published monthly by the National Association of Realtors, tracks the number of previously owned single-family homes, condos, and co-ops that closed during the month. Resales make up the large majority of all home sales in the US — new construction, by comparison, is a much smaller slice — which is what gives this report its weight as the primary read on overall housing market activity.

Because the figures are based on closed transactions rather than signed contracts, existing home sales data reflects buying decisions made roughly a month or two earlier, when the mortgage application and closing process began. That lag is worth keeping in mind when comparing this report against more forward-looking housing indicators like pending home sales or mortgage applications.

What it signals about demand and affordability

Alongside the sales pace, the report includes median home prices and the inventory of homes available for sale, expressed as months of supply at the current sales rate. Together, these give a fuller picture than the headline sales number alone: rising sales alongside tight inventory and climbing prices points to strong demand outstripping supply, while falling sales alongside rising inventory suggests buyers are pulling back, often in response to affordability pressure from higher prices, higher mortgage rates, or both.

Because most existing homeowners carry a mortgage locked in at whatever rate prevailed when they bought or last refinanced, a sharp rise in current mortgage rates can also freeze up supply — owners with a low locked-in rate become reluctant to sell and take on new financing at a much higher rate, tightening inventory even when demand is otherwise flat. That dynamic has made inventory levels as important to watch as the sales pace itself in recent cycles.

Market reaction

Existing home sales data moves markets less sharply than payrolls or CPI, but it still feeds into the broader read on consumer health and rate sensitivity, given how directly it's tied to affordability and financing costs. Homebuilder and real estate related stocks, along with regional bank stocks with mortgage exposure, tend to be the most responsive equity segments. Bond markets read the data mainly through the affordability lens — data confirming that higher rates are meaningfully cooling housing activity can reinforce expectations for eventual rate cuts, supporting Treasury prices.
