In the first quarter of 2025, the Federal Housing Finance Agency (FHFA) released its latest House Price Index (HPI) report. At first glance, the numbers might not seem too surprising—until you realize that this is the first report based on a newly updated set of metropolitan delineations issued by the U.S. Office of Management and Budget (OMB). What sounds like a small technical change is, in reality, a restructuring of how housing markets are statistically defined and understood.
This quiet but impactful shift doesn’t just change the formatting of data—it rewrites the geographic framework that underpins how we calculate price trends, evaluate investment risk, and even make personal decisions about where to live or buy property. And for property investors, homeowners, or even renters—especially among the overseas Chinese community living or working in the U.S.—these changes matter more than they may think.
Urban boundaries in the U.S. have always been fluid, shaped by decades of migration, policy, and economic development. But recent transformations—such as the rise of remote work, the migration of tech jobs out of Silicon Valley, and shifts in population centers—have accelerated the need for an updated definition of what constitutes a metropolitan area. Many suburban counties that were previously seen as commuter zones have become full-fledged parts of major urban economies. In response, the OMB revised its metropolitan delineations to better reflect today’s patterns of living, working, and economic interconnection.
To understand how these new delineations impact property markets, the FHFA conducted a test run: it applied the new definitions to data from the fourth quarter of 2024 to see how the updated boundaries would affect price indexes. The results were telling. In some areas, the index values shifted dramatically—highlighting how important accurate geographic definitions are to interpreting market trends.
Let’s take Atlanta as a prime example. The revised delineation expanded the Atlanta-Sandy Springs-Alpharetta metropolitan area to include several previously excluded suburban counties like Paulding and Barrow. These areas have generally had lower home prices and slower growth. As a result, when added to the broader metro area calculation, they pulled the overall HPI down by around 1.5%. But this drop doesn’t mean Atlanta’s housing market is weakening. On the contrary, it reveals the importance of examining sub-regional dynamics. High-value areas like Alpharetta, for example, remain strong and continue to attract high-income buyers. For homeowners or investors with property in core Atlanta neighborhoods, the revised data actually underscores their holdings’ resilience and long-term value.
Contrast that with the San Francisco Bay Area. Here, the metropolitan area was trimmed—several fringe counties with weaker markets were removed from the core San Francisco-Oakland-Berkeley definition. The result? The index jumped by over 2.3%, as the calculation now reflects only the performance of more affluent and economically robust areas. This serves as a powerful reminder: even in an era of high interest rates and softening outer-ring demand, central urban cores—especially those with strong employment bases and high-quality schools—still hold their value. Many buyers who chased affordability in far-out Bay Area suburbs during the 2020–2022 boom now face underperforming assets, while core property owners continue to see stability.
In Texas, Austin tells a different story. The newly defined Austin-Round Rock-Georgetown area now includes Georgetown, a rapidly growing city that has become tightly connected to Austin through jobs, transit, and housing. Over the past two years, Georgetown has seen a surge in home prices, thanks to new tech development and a steady inflow of new residents. With this area now included in the broader metro index, the entire region’s HPI jumped by about 3.7%. This is a textbook example of how formerly overlooked suburban zones are becoming hotbeds for long-term investment—especially in states like Texas, which offer business-friendly policies, ample land, and strong demographic trends.
From these three examples, one truth becomes clear: changes in metro delineations are more than just statistical updates—they’re reflections of real structural shifts in population, investment, and economic momentum. These changes influence everything from how banks assess mortgage risk to how local governments allocate infrastructure funds and resources. As investors or homeowners, especially in immigrant communities, we must learn to read beyond the headlines and into the evolving patterns these technical changes reveal.
Looking forward, which regions should be on your radar in the new delineation landscape? Based on recent trends and the updated HPI framework, here are five standout areas worth watching closely. First, North Austin, Texas, is emerging as a magnet for population growth, with high-tech industries and updated zoning working in its favor. Second, Tampa–St. Petersburg in Florida continues to benefit from retiree migration and tax incentives. Third, Southeast Atlanta shows promising signs of renewed infrastructure investment under the new boundary system. Fourth, the Inland Empire region in California still benefits from spillover effects from L.A. and San Francisco despite recent price dips. And fifth, Chicago’s western suburbs are slowly rebounding, thanks to improved transit and education access.
So what should overseas Chinese and international investors take away from all this?
First, stop thinking in averages. A regional HPI may rise or fall, but that doesn’t necessarily reflect what’s happening in your neighborhood or zip code. A 2% decline in the metro index may mask a 5% rise in a specific, high-demand school district. Second, recognize the strategic opportunity in areas that have just been reclassified into major metro zones. When a suburban area is officially absorbed into a metropolitan statistical area, it typically signals an upcoming wave of public investment—in transit, schools, healthcare, and more—that will drive future property appreciation. Third, make sure your lender or financial advisor is using up-to-date delineations when assessing your property value or loan eligibility. Using outdated definitions can result in lower appraisals, higher down payment requirements, or even a rejected loan.
Ultimately, this change in HPI methodology is part of a much larger story—the ongoing evolution of American cities. Cities are not static—they grow, shrink, and change shape in response to real human decisions and economic forces. Understanding how these changes affect the housing market gives you a major advantage as an investor or buyer.
Real estate is not just about how much a home is worth today—but about what the neighborhood will become tomorrow. With delineation changes now in place, it’s more important than ever to look beyond static numbers and examine the deeper trajectory of each area. Ask yourself: is this neighborhood gaining momentum, infrastructure, and people? Or is it falling behind?
