Data centers show widely varying effects on local housing markets, with no consistent pattern of raising or lowering nearby home values, according to a new study from the National Association of Realtors. The report analyzed more than 3,200 counties and surveyed Realtor members to assess how the facilities affect housing, employment and real estate activity.
Researchers identified 1,474 data centers across 251 counties, meaning 92% of all counties have no mapped facilities. Counties with data centers generally have higher home values and stronger long-term job growth, but the association emphasized that correlation does not equal causation. "Our research does not support saying that a data center will automatically lower or raise nearby home values," said Nadia Evangelou, principal economist and director of real estate research for NAR and lead author of the report.
Loudoun County, Virginia, leads the nation with 213 facilities, followed by Santa Clara County, California, with 75. Maricopa County, Arizona, and Prince William County, Virginia, each have 63. The economies of these markets vary dramatically. Loudoun County's data center industry grew from an internet exchange established in the 1990s, while Grant County, Washington, attracted facilities through low-cost hydropower from the Columbia River. Licking County, Ohio, has seen rapid expansion driven by land availability near Columbus, the report said.
The survey of Realtor members found mixed perceptions of data center impact on nearby residential property values. Twenty-five percent reported a positive impact and 22% reported a negative impact. Roughly one third of respondents said they were not sure, with the remainder citing no changes. On demand for nearby residential properties, perceptions trended slightly more negative, with 19% reporting increased demand and 26% citing a decrease.
The commercial sector showed stronger positive perceptions. Half of respondents reported a positive impact on nearby commercial property values, with 22% saying values increased by more than 10%. Industrial properties experienced the most demand near data centers, cited by 58% of respondents, followed by land at 38%. The report's data analysis found that real estate firms make up roughly 6.4% of all businesses in counties with the highest concentration of data centers, compared with 4.9% in counties with no data centers.
Realtor respondents reported that the top concerns among clients related to nearby data centers were energy costs, cited by 61%, and water use, cited by 56%. Environmental contamination followed at 43% and impact to the immediate landscape at 32%. The report's data analysis found that residential electricity rates increased faster from 2020 to 2024 in counties with 10 or more data centers, rising 21.4%, than in counties without data centers, which rose 15.7%. However, the increase did not consistently rise with the number of facilities.
Counties with 10 or more data centers have median household incomes of about $89,000, compared with $64,000 in counties without data centers, the report said. Adults in those counties are also more likely to hold bachelor's degrees, with 41% compared with 22%. Employment from 2014 to 2024 grew about 16% in counties with 10 or more data centers, compared with 2% growth in counties without data centers. More recent growth has slowed, with the high-concentration group seeing median employment growth of about 0.6% from 2024 to 2026.
