How Hyperscale and Powered Shell Financing Works in Columbus
Columbus has moved decisively into the top tier of North American data center markets, and the financing ecosystem serving hyperscale and powered shell development here reflects that status. Amazon Web Services, Google, and Microsoft have collectively committed billions of dollars to Ohio data center campuses, with the Columbus metro absorbing the majority of that activity. That concentration of investment-grade tenancy has made the market legible to institutional capital in a way that many secondary Midwest markets are not. Life insurance companies and large bank syndicates that once focused almost exclusively on Northern Virginia and Phoenix are actively underwriting Columbus deals on their own terms, without requiring sponsors to argue the market's merits from scratch.
The programmatic logic of hyperscale and powered shell financing is straightforward: a creditworthy hyperscale tenant commits to a 10- to 20-year NNN lease, often paired with a power purchase commitment ranging from 50 to 500 megawatts, and that lease becomes the primary underwriting instrument. The real estate is largely incidental. Lenders are pricing the credit of AWS or Azure, not the Columbus industrial submarket. That dynamic is particularly favorable in Columbus given Ohio's HB 9 data center equipment tax abatement, which materially improves tenant economics and has been a documented driver of hyperscale leasing activity in the metro. Deal activity concentrates in New Albany, Hilliard, Plain City, and Obetz, where large-site assemblages with substation access and fiber diversity have attracted the most advanced campus development.
Powered shell deals sit just below full hyperscale campuses in scale but share the same financing architecture. A developer delivers a conditioned shell with utility-grade power infrastructure in place, and the hyperscale tenant completes the fit-out under a long-term lease. Construction costs for the shell itself typically run between 150 and 300 dollars per square foot, but the power and mechanical infrastructure layer adds 500 to 1,500 dollars per square foot depending on power density requirements. Lenders underwrite the total cost basis against the lease economics, and the resulting debt service coverage profiles are among the strongest in commercial real estate when the tenant is investment-grade.
Lender Appetite and Capital Stack for Columbus Hyperscale and Powered Shell
Life insurance companies are the dominant execution path for stabilized, NNN-leased hyperscale assets in Columbus. When the lease counterparty is AWS, Microsoft Azure, or Google, life companies will underwrite on the strength of that credit and price accordingly. In the current rate environment with the 10-year Treasury around 4.3 percent, life company spreads for investment-grade hyperscale leases are running approximately 125 to 175 basis points over the 10-year, producing all-in rates in the mid- to upper-5-percent range for the best deals. LTV for stabilized life company execution lands between 55 and 65 percent, with 25- to 30-year amortization schedules and yield maintenance or make-whole prepayment structures that reflect the long-duration nature of the underlying leases. CMBS has been used selectively on single-tenant stabilized deals with strong lease documentation, generally in the 60 to 70 percent LTV range, but the data center capital markets in Columbus skew toward balance sheet lenders who want the flexibility to accommodate the technical complexity of the collateral.
Construction financing for ground-up hyperscale or powered shell development is sourced from national bank syndicates or specialty data center construction funds. With SOFR currently around 3.6 percent, pre-leased hyperscale construction loans are pricing at SOFR plus 200 to 350 basis points depending on sponsor strength, lease commencement certainty, and the depth of the syndication. LTV at the construction level typically runs 55 to 65 percent of total project cost when a lease is in place. Larger campus developments with staged delivery often layer mezzanine or preferred equity above the senior construction loan to reach the leverage required for speculative phases. Huntington National Bank and Fifth Third Bank are active in the Columbus market but are generally better positioned for smaller colocation and edge computing assets rather than gigawatt-scale hyperscale campuses, which require syndication capacity those institutions typically cannot lead alone.
Underwriting Criteria That Matter in Columbus
Lease credit and lease structure are the first and second items any lender will examine, in that order. A lease to an investment-grade hyperscale operator with no termination rights, full NNN expense pass-throughs, and contractual rent escalations is a fundable asset almost independent of everything else. Where lenders in Columbus are spending more time is on power delivery timelines. AEP Ohio's transmission infrastructure has been under significant strain from the volume of data center development in the pipeline, and deals where the power commitment is not yet confirmed or where substation upgrades are subject to utility approval timelines carry real execution risk in underwriting. Lenders will ask for utility confirmation letters and interconnection agreements before issuing term sheets on construction deals.
Beyond power, lenders scrutinize site control quality, fiber diversity documentation, and sponsor data center operating experience. Columbus has attracted a range of developers with varying degrees of technical expertise, and institutional lenders distinguish sharply between sponsors who have delivered hyperscale campuses before and those entering the sector opportunistically. Cooling infrastructure, water access for large thermal loads, and generator redundancy documentation all factor into technical underwriting that life companies and bank syndicates conduct alongside their financial analysis. The Ohio HB 9 abatement is a positive underwriting factor but lenders want to see the abatement confirmed and documented rather than assumed.
Typical Deal Profile and Timeline
A representative Columbus hyperscale deal in the current market involves a 200- to 500-megawatt campus development in New Albany or Plain City, with a pre-executed lease to a named hyperscale tenant, a total capitalization between 300 million and 1 billion dollars, and a construction timeline of 18 to 36 months depending on scope and phasing. Sponsors lenders are pursuing in this market have prior hyperscale or large-format data center delivery on their resume, strong balance sheets capable of absorbing cost overruns, and existing relationships with hyperscale procurement teams. Institutional equity partners or co-sponsors with data center operating credentials are common on larger transactions.
From signed LOI to construction loan closing, sponsors should budget 90 to 150 days, with meaningful time consumed by technical due diligence, syndication assembly, and AEP interconnection documentation. Permanent loan placement on a stabilized asset typically runs 60 to 90 days from lease commencement with a lender who has already underwritten the credit. Deals that miss on utility confirmation or lease finalization during the process frequently restart the lender clock, so sequencing those workstreams ahead of financing engagement materially compresses overall timeline.
Common Execution Pitfalls Specific to Columbus
Power delivery uncertainty is the most common deal-stopper in Columbus right now. The volume of active and planned data center development in the metro has created real queuing pressure in AEP Ohio's interconnection process. Sponsors who have a signed lease but an unresolved substation upgrade or interconnection timeline will find lenders unwilling to proceed past preliminary diligence. Confirm power delivery dates in writing before engaging the capital markets.
Speculative pipeline saturation is a secondary concern lenders are tracking. Columbus has more powered shell and hyperscale development in predevelopment than any prior cycle in the market's history, and lenders are beginning to ask sharper questions about absorption timing and competitive positioning for deals that are not already pre-leased. Unanchored speculative shells face materially tighter credit availability than pre-leased deals.
HB 9 abatement assumptions embedded in sponsor underwriting have created friction with lenders when the approval is not yet in hand. The abatement is real and material but is not automatic, and lenders underwriting to a cost basis that assumes the abatement without documentation will require downward adjustments to proceeds or increased reserves.
Finally, sponsors underestimate the depth of technical due diligence institutional lenders conduct on data center collateral. Lenders may engage independent technical advisors to review power infrastructure design, cooling systems, and redundancy specifications before issuing a commitment. Deals that enter this process with incomplete engineering documentation extend timelines and occasionally fail to close on favorable terms.
