When a family or individual buys a home in the Tri-Cities, the transaction doesn’t end at the closing table. It sets off an economic chain reaction of jobs supported, services purchased, and neighborhoods stabilized. It ripples through the total and individual county economies. And the numbers behind that ripple are larger than some realize.

The takeaway for consumers, business leaders, and policymakers alike is straightforward. Residential real estate is not just a housing market metric. It’s a foundational economic engine. Every closing, every deed transfer, every first-time buyer who plants local roots sends economic activity cascading. The context comes from the annual analysis of the impact of home sales by the National Association of Realtors® (NAR). 

For Northeast Tennessee Association of Realtors® (NETAR) members, these numbers represent more than data points. They are a reminder of the role they play not just in helping clients find homes, but in sustaining the economic vitality of the communities they serve. 

The 7,745 residential sales recorded by NETAR in 2024 generated a total economic impact of $934 million. When combined with the $2.4 billion in total sales volume, they contributed an estimated $3.3 billion to regional economic activity. That figure does not include off-MLS sales or the region’s commercial real estate sector.  

To put that in context: the gross domestic product (GDP) of the nine counties in the NETAR region totaled $34.9 billion in 2024. Real estate activity accounted for a meaningful share of that economic output. 

The NAR model for Tennessee breaks down each home sale’s total $120,600 economic impact into four components: 

Real estate industry income — At 27.9% of the per-sale impact, this is the income flowing directly to real estate professionals. It covers agent commissions, broker fees, and moving-related expenses. Across 7,745 transactions, that translated to roughly $260 million. 

Home purchase-related spending — Representing 4.7% of total impact, this category captures the furniture, appliances, and remodeling expenditures that new owners consistently make after a purchase, based on National Association of Home Builders (NAHB) research. That adds up to approximately $43.9 million in discretionary spending. 

Multiplier effect — At 15.6% of impact, this component, derived from Macroeconomic Advisors modeling, measures income earned across multiple sectors as a result of a home sale that is then re-spent in the local economy. A mortgage processor, an inspector, a moving company employee — each paycheck that results from a transaction circulates further. Regionally, the multiplier effect added an estimated $145.7 million in economic activity in 2024. 

New home construction — The largest single component at 51.7%, this figure is derived from a U.S. Census Bureau formula that estimates one new home is constructed for every six existing-home sales. That represents roughly $482.9 million in construction-related materials, permits, and contractor services. 

Since NAR’s analysis is based on data from the Bureau of Economic Research and the U.S. Census, there’s a time lag. Data from 2025 from the federal government sources will be the basis of next year’s report, which will include input from the National Association of Home Builders, Macroeconomic Advisors, NAR, and NETAR.
