What are Existing Home Sales?
Existing home sales measure the number of previously owned residential properties that change hands during a given period. Published monthly by the National Association of Realtors (NAR), the existing home sales report is the most widely followed housing market indicator in the United States. Unlike new home sales, existing sales are counted at the time of closing, making them a coincident indicator that reflects recent market activity rather than forward-looking demand.
Existing home sales typically account for 85-90% of all residential transactions. The report includes the sales pace (seasonally adjusted annual rate), median and average prices, inventory levels, months of supply, and regional breakdowns. For real estate investors, this data provides the foundation for understanding market conditions at both national and local levels.
Why this metric matters for investors
Existing home sales volume directly affects the opportunity set for investors. Higher sales volume means more transaction activity, more comparable sales for property valuation, and generally healthier market conditions. Lower sales volume can indicate buyer hesitation, financing difficulties, or affordability constraints that affect both acquisition and disposition strategies.
For wholesalers specifically, the existing home sales trend reveals how active cash buyers are in the market. Cash transactions are reported as a percentage of total existing home sales (typically 25-35%). A rising cash buyer percentage signals strong investor demand, which is favorable for disposition. A declining percentage suggests investors are pulling back.
Median price trends
The median existing home sale price is closely watched as a gauge of affordability and market direction. Year-over-year price changes tell you whether values are rising, flat, or declining in the broader market. While local conditions can vary dramatically from national trends, the national data provides context for understanding whether your local market is outperforming or underperforming.
Keep in mind that median prices can be skewed by the mix of homes selling. If luxury home sales increase as a share of total sales, the median price rises even if individual home values are flat. For accurate local analysis, use MLS data filtered to the specific neighborhoods and property types relevant to your investing strategy.
Sales and inventory interaction
Existing home sales and inventory levels interact to define market conditions. Sales divided by inventory equals the absorption rate, expressed as months of supply. When sales are strong and inventory is low, months of supply drops below 4 and the market favors sellers. When sales slow and inventory rises above 6 months, buyers gain negotiating power.
Investors should track both the level and direction of these metrics. A market with 3 months of supply that is rising toward 4 months is loosening -- a potential early signal of better buying opportunities ahead. A market with 7 months of supply that is declining toward 5 months is tightening -- a signal that current buyers may face more competition soon.
Regional and local differences
National existing home sales data is useful for understanding the macro environment, but real estate is fundamentally local. The South typically leads in sales volume due to population growth and relative affordability. The West tends to have the highest prices but lower volume. The Northeast has the most seasonal variation, with sales dropping significantly in winter months.
Your local MLS provides the most actionable data. Track existing home sales in your specific target neighborhoods, filtered by price range and property type. This ground-level analysis is what informs actual investment decisions -- national data just sets the context.
