Headline cap rates in Southeast office markets tell you something, but not the thing you need to know before committing capital. In mid-2024, the aggregate Southeast office cap rate — the number that shows up in broker surveys and research reports — appeared relatively stable in the 6.8–7.4% range. But strip out the transaction mix, and a different picture emerges: trophy-class CBD product in Atlanta and Charlotte was trading between 5.9% and 6.4%, while suburban flex-office assets in secondary corridors were pricing at 8.5% to over 9%. That is not a single market. That is two markets wearing the same label.
Understanding why the spread exists — and where it is likely to go — is the actual work of office underwriting in 2024 and into 2025. Here is what the deal-level comps are showing, and how to read them more precisely.
The Composition Problem in Reported Cap Rates
Reported cap rate averages aggregate every closed transaction above a certain lot size. When institutional capital concentrates its buying activity in a narrow segment — as has been the case with trophy CBD office — those deals compress the average. When those same buyers pull back, the absence of transactions in that tier does not move the average dramatically, because the relative transaction count remains small.
The problem is that analysts use the aggregate number as a market benchmark when it is really a weighted blend of at least three structurally different product segments: Class A CBD, Class A suburban, and older Class B/C flex product. Each of these has its own buyer pool, its own financing environment, and its own NOI trajectory. Treating them as one "office market" produces a cap rate average that does not accurately describe any of the three segments.
A more useful discipline is to split your comp set by product type before comparing anything. When we segment Southeast office transactions closed in H1 2024 at the parcel level — controlling for building vintage, location-grade, and occupancy at time of sale — the divergence becomes unambiguous. Trophy product in supply-constrained submarkets (South End Charlotte, Midtown Atlanta) continued to see demand from institutional and cross-border capital. The financing environment for that tier has been manageable: long-term in-place leases from credit tenants allow lenders to underwrite DSCR at acceptable margins even with elevated base rates.
What Is Compressing Trophy Cap Rates
In the Southeast specifically, three factors explain why select Class A assets have continued to attract competitive bidding despite the broadly difficult office environment nationally.
First, flight-to-quality tenant migration. Large-footprint tenants with lease expirations in 2023–2025 have used the moment to trade up — leaving older product in suburban corridors and consolidating into trophy space. The buildings that captured these renewals entered the transaction market with strong in-place NOI and cleaner vacancy profiles than the national average would suggest.
Second, population and employment growth differentials. Charlotte MSA added workforce in the financial services, technology, and healthcare sectors through 2022–2024 at rates that outpaced most Midwestern and Northeast markets. That net employment growth supports occupancy in the subset of office product co-located with that workforce. Parcel-level comp analysis shows a notable correlation between drive-time proximity to residential density growth and lease-up velocity in office assets purchased post-2022.
Third, supply constraint at the top tier. Entitlement timelines in Charlotte CBD and parts of Buckhead Atlanta have extended significantly. New office deliveries in trophy locations are scarce through 2025. Scarcity in a segment where demand has partially recovered creates pricing tension that brokerage averages obscure.
Where Suburban Flex Is Widening
The other side of the spread is instructive too. Suburban Class B office and older flex-office inventory in corridors like Pineville, Concord, and South Mecklenburg is not suffering from a temporary demand dip. The absorption numbers at the submarket level show sustained negative net absorption through H2 2023 and into Q1 and Q2 2024. These assets are losing tenants to both the trophy CBD flight-to-quality dynamic and to work-from-home persistence among small-to-mid-size occupiers.
Cap rates at 8.5–9.5% for this product tier are not aggressive pricing; they reflect the cost of capital plus the discount for elevated vacancy and uncertain lease-up timelines. Consider a plausible example: a 65,000 SF suburban flex building in the Pineville corridor with 38% vacancy and a WALT of 2.1 years. At a 9.1% cap on actual in-place NOI, the effective price-per-SF is in the $65–72 range — barely above replacement cost for older product. The buyer's thesis at that price is either a heavy-lift repositioning or a land-value play if the parcel is zoned for mixed-use reuse. Neither is wrong; both require underwriting assumptions that diverge fundamentally from a stabilized Class A investment thesis.
We are not saying suburban flex is uninvestable — there are genuine value-add opportunities in the segment, particularly where submarket-level analysis shows improving demographics and mixed-use rezoning pressure. What we are saying is that bundling a 9.1% suburban flex deal with a 6.1% trophy CBD transaction into the same "Southeast office" data series produces a number that serves neither buyer's decision-making.
How to Read the Comps More Precisely
Practical comp selection for office assets in this environment requires more granularity than most automated valuation tools apply by default. Three adjustments matter most.
Use-class coherence. Restrict your comp set to same-tier product. A Class A CBD tower is not comparable to a Class B suburban campus for cap rate benchmarking purposes, even if both are nominally "office" and within five miles. Blending them introduces more noise than signal.
Recency decay. Transactions from 2021 and early 2022 occurred in a materially different financing environment — essentially zero-cost debt that supported cap rate compression across all asset classes. For 2024 office underwriting, weighting transactions from mid-2022 forward more heavily, and discounting pre-rate-cycle comps, produces a more defensible market baseline. A common approach is to apply a time-adjustment of 50–75 basis points per year for pre-2022 transactions in office, though this varies by specific submarket conditions.
Occupancy-at-sale disclosure. Many public records transactions and aggregated data sources do not capture occupancy rates at the point of sale. A 7.2% cap on an 82%-occupied building and a 7.2% cap on a 94%-occupied building are categorically different underwriting propositions. Where occupancy is obtainable — either from seller disclosure, rent roll review, or property-level data services — it should be a primary filter, not an afterthought.
The Spread as a Forward Signal
The trophy-versus-flex cap rate spread in Southeast office is not a static feature of the current market. It is a signal about the direction of capital allocation and, by extension, a preview of which asset types will see price discovery and which will see extended price stagnation.
For investors underwriting Southeast office acquisitions in 2024–2025, the takeaway from parcel-level comp analysis is specific: the headline market number is not your comp. Your comp is the set of transactions within your product tier, within your submarket, from the last 18 months, with disclosed occupancy conditions. That set will be smaller than you might like — which is itself a data point about market depth and liquidity risk for the asset type you are considering.
The broker surveys will catch up to what the comps are already showing, usually with a lag of two to four quarters. Parcel-level data analysis compresses that lag. That is precisely the edge that disciplined deal-level comp work provides in a diverging market.
