Cap rates across Sun Belt markets have compressed significantly, squeezing yields for investors who bought the narrative. Here is where the math still works — and where it does not.
Cap rates across Phoenix, Atlanta, Nashville, Dallas, and Tampa have compressed to the point where the original Sun Belt thesis — buy yield, ride population growth — no longer holds at face value. Investors who underwrote at 6.5% in 2021 are now staring at stabilized assets trading at 4.8% to 5.2%, with debt costs that have not moved in their favor. The math has shifted. The question is what disciplined investors do next.
This post breaks down where compression has landed in each major Sun Belt market, what is driving it, and where yield still exists for investors willing to look one level deeper.
Cap rate compression is not a mystery. When capital floods into a market faster than supply can respond, asset prices rise and yields fall. The Sun Belt absorbed an extraordinary amount of institutional and private capital between 2020 and 2023, driven by population migration, remote work tailwinds, and a rate environment that made yield-seeking mandatory.
The 2024 Emerging Trends in Real Estate report from ULI documented the dynamic precisely: gateway market investors moved downstream into Sun Belt metros in search of yield, and that capital repriced the assets they targeted. The result is compression that is concentrated in specific asset classes and submarkets — not uniform across every Sun Belt zip code.
The important distinction: compression is most severe in Class A multifamily in core submarkets. Value-add, secondary Sun Belt metros, and alternative asset classes — including short-term rental properties and mixed-use — have not compressed at the same rate. The gap between perceived risk and actual risk in those segments is where yield still lives.
Phoenix was the poster market for Sun Belt appreciation. Between 2020 and 2022, multifamily cap rates in the Phoenix metro compressed from roughly 5.5% toward 4.5%, driven by a combination of rent growth and institutional demand.
Where Phoenix stands now: New supply has arrived in volume. Phoenix delivered more than 18,000 multifamily units in 2024, and absorption has not kept pace. Cap rates in core submarkets like Scottsdale and Tempe have stabilized in the 4.8% to 5.3% range — but concessions are widespread, and effective rents are running 8% to 12% below asking in some submarkets.
For investors underwriting Phoenix today, the math requires a longer stabilization horizon than two years ago. Class B value-add in East Mesa and Chandler still offers a credible path to a 5.8% to 6.2% going-in yield if the basis is disciplined and the renovation scope is underwritten conservatively.
The error most investors make in Phoenix right now: underwriting to 2022 rent comps. The competitive set has expanded, and new supply is setting the market rate. Any Phoenix underwrite that does not account for 12 to 18 months of occupancy softness in Class A submarkets is not credible.
Atlanta is the Sun Belt outlier in the current cycle. Cap rates compressed here as they did elsewhere, but Atlanta's demand fundamentals — corporate relocations, a diversified employer base, and population growth that has not reversed — have provided a floor that Phoenix and Nashville cannot match at the same confidence level.
Where Atlanta stands now: Core multifamily in Buckhead and Midtown is trading in the 4.5% to 5.0% range. The real opportunity is in Atlanta's secondary ring: Gwinnett County, Clayton County, and the I-20 corridor east of the city. These submarkets are seeing 6.0% to 6.8% going-in cap rates on Class B assets, with rent growth still positive at 3% to 4% annually.
Atlanta's build-to-rent sector deserves specific attention. Single-family rental communities in the outer Atlanta suburbs have not compressed as aggressively as institutional multifamily because the capital targeting them is less concentrated. Investors who can execute at the neighborhood level rather than the institutional level are finding returns that the major players cannot access.
For accredited investors evaluating Atlanta deals, the question to pressure-test is sponsor experience in the specific submarket. A sponsor who operates in Buckhead is not automatically qualified to underwrite Gwinnett. Selly's accredited investor deal matching service screens for exactly this — submarket depth is part of the 360-degree verification before any deal reaches the investor network.
Nashville became one of the most aggressively underwritten Sun Belt markets in the 2021 to 2023 period, and the hangover is real. The market absorbed enormous capital, cap rates compressed into the low 4% range for prime assets, and then supply responded — with roughly 15,000 multifamily units delivered in 2024 alone in the Nashville metro.
Where Nashville stands now: Effective rents in the Urban Core and Gulch submarket have softened, and Class A operators are offering significant lease-up concessions — one to two months free rent is common. Cap rates have not dramatically re-expanded yet because transaction volume has slowed; sellers are not willing to mark down, and buyers are not willing to pay the prior peak pricing. The market is in price discovery.
Nashville's secondary ring — Murfreesboro, Smyrna, Hendersonville — presents a different picture. These markets did not attract the same institutional capital during the compression cycle, which means they did not compress as far. Going-in cap rates of 5.8% to 6.5% are available in those submarkets on well-located B-class assets, and the renter demand from Nashville's spillover population growth remains intact.
The 2025 Emerging Trends in Real Estate report from ULI identified Nashville as a market where near-term caution is warranted in core, but secondary suburban submarkets retain fundamental demand strength. That framing is consistent with what disciplined underwriting produces when you run the numbers at the submarket level rather than the metro level.
Dallas has the deepest and most liquid real estate market of any Sun Belt metro. It also has the most active development pipeline. Texas's permissive regulatory environment means that when demand rises in Dallas, supply follows — which acts as a structural cap on how far rents and values can run before new product arrives to reset the ceiling.
Where Dallas stands now: North Dallas suburbs — Frisco, Allen, McKinney — have absorbed significant new multifamily supply, and Class A cap rates are holding in the 4.9% to 5.4% range on stabilized assets. South Dallas submarkets — DeSoto, Duncanville, Cedar Hill — remain meaningfully underinvested relative to their population and employment growth, with cap rates in the 6.2% to 7.0% range on quality Class B product.
Dallas also has one of the most active short-term rental markets in Texas. Neighborhoods like Deep Ellum, Bishop Arts, and the Medical District see strong STR demand that is not fully captured in traditional multifamily underwriting. Owners who have converted units or operated purpose-built STR assets in Dallas have outperformed long-term rental returns on a RevPAN basis in several of these submarkets — a fact that remains underappreciated by institutional capital allocating to the metro.
Tampa does not get the same coverage as Phoenix or Nashville, but it has experienced some of the most significant cap rate compression in the Sun Belt — driven by Florida's migration tailwinds and a relatively constrained supply pipeline compared to Texas markets.
Where Tampa stands now: Downtown Tampa and South Tampa multifamily is trading at 4.4% to 5.0% on stabilized Class A assets. The migration story is real — Tampa has absorbed consistent population growth from the Northeast and Midwest — but that story is now priced into core submarkets.
Where Tampa's math still works: Hillsborough County's eastern submarkets (Brandon, Valrico, Riverview) and Pinellas County's secondary markets (Largo, Clearwater inland) have not attracted the same institutional capital. These areas are seeing 5.8% to 6.5% going-in cap rates on Class B value-add assets, with a renter profile that is more stable than the high-turnover Class A market.
Tampa's coastal and short-term rental market — particularly the Clearwater Beach and St. Pete Beach corridor — deserves a separate underwriting lens entirely. STR properties in that corridor are not competing with multifamily on a cap rate basis; they are underwritten on RevPAN and ADR metrics, and the tourist demand drivers that support those returns are structurally different from the migration story driving long-term rental demand.
For context on how Selly evaluates STR opportunities that fall within a broader portfolio, the accredited investor deal matching program includes hospitality-adjacent assets that clear the same 360-degree verification applied to every deal on the platform.
The pattern across all five markets is consistent: yield compression is concentrated at the top of the market — Class A, core submarket, institutional-grade assets. The further you move from that profile, the more opportunity exists.
Secondary Sun Belt markets worth tracking for going-in cap rates above 6.0%:
The discipline required in these markets is higher, not lower, than in a primary Sun Belt metro. Liquidity is thinner, the buyer pool is smaller, and exit assumptions must be underwritten conservatively. But the going-in yield more than compensates for that execution risk for investors with the right hold-period horizon.
For a broader view of how Sun Belt fundamentals compare to specific Texas markets, the post on Houston real estate market versus Sun Belt cities in 2025 provides additional context on where Houston fits in this compression picture.
The investors who are not paralyzed by compression share three characteristics.
First, they have moved their return target to total return rather than going-in yield. A 5.2% cap rate deal in Atlanta's northern suburbs with 4% annual rent growth and a credible 10-year hold competes favorably with a 6.5% going-in yield in a secondary market where rent growth is flat and the exit cap is uncertain.
Second, they are underwriting to current debt costs, not 2021 assumptions. A deal that pencils at 5.5% cap on a 3.5% fixed rate does not pencil at 5.5% cap on a 6.2% floating rate. The investors who are executing today have structured their debt conservatively — longer fixed periods, meaningful amortization, reserves that can absorb a 10% rent softness scenario.
Third, they are asking the right questions of sponsors. Compression-era returns required minimal operational skill — rising rents covered a lot of execution errors. In the current environment, operator quality matters more. A syndicator who has only operated in a rising market has not been tested. For a structured framework on how to vet sponsor credentials before committing capital, the post on 5 questions accredited investors should ask before committing capital is worth reviewing before any LP commitment.
Cap rate compression across Sun Belt markets is real, and investors who are still underwriting to 2021 assumptions will find that the math does not close. But the investors treating Sun Belt as a single, uniformly overpriced market are leaving disciplined opportunities on the table in secondary metros, secondary ring submarkets, and alternative asset classes that institutional capital has not yet repriced.
Selly works with accredited investors who want curated exposure to vetted operators running assets in markets where the numbers still work. Every deal that reaches the investor network has passed 360-degree verification — financials stress-tested, sponsor track records confirmed, market assumptions benchmarked against current data.
