How Enterprise Single-Tenant Data Center Financing Works in Columbus
Columbus has quietly become one of the most consequential data center markets in the country, and the enterprise single-tenant segment sits at the heart of that story. Unlike hyperscale campuses being built by Amazon Web Services, Google, and Microsoft across central Ohio, enterprise single-tenant facilities serve a fundamentally different purpose: they house the mission-critical IT infrastructure of a single financial institution, government agency, healthcare system, or Fortune 500 corporate tenant. These are purpose-built or owner-operated assets with power footprints typically between 1 and 20 megawatts, built and operated to stringent compliance standards including SSAE 18 SOC 2, FISMA, HIPAA, and PCI DSS depending on the tenant profile. The financing structures that support them are driven almost entirely by tenant credit quality and lease structure rather than by the real estate fundamentals that govern most commercial property types.
Within the Columbus metro, enterprise single-tenant data center activity concentrates in a handful of submarkets that offer the combination of available land, grid infrastructure, and fiber connectivity that these tenants require. New Albany has emerged as the marquee submarket given its proximity to the OhioHealth and Amazon campus activity, while Dublin, Hilliard, and Westerville attract financial services and insurance tenants drawn to established suburban office corridors. Obetz and Grove City serve more industrial-grade enterprise users, and Plain City and Gahanna offer newer development sites as inner-ring options tighten. Ohio's HB 9 data center equipment tax abatement makes the entire metro attractive from a total cost of occupancy standpoint, which strengthens the underlying lease economics that lenders underwrite.
The financing thesis for these assets in Columbus is straightforward for lenders who have done the work to understand the collateral: you have an investment-grade or near-investment-grade tenant, a long-term NNN lease tied to core IT infrastructure that the tenant cannot easily relocate, and a market with proven institutional demand validating long-term property values. The complexity arises in single-purpose collateral risk, power availability constraints, and the technical diligence burden that most generalist lenders are not equipped to navigate. Sponsors who approach this market with clean lease structures, creditworthy tenants, and an understanding of how lenders think about alternative-use scenarios will find capital available at competitive terms.
Lender Appetite and Capital Stack for Columbus Enterprise Single-Tenant Data Center
Life insurance companies are the most competitive permanent lenders for stabilized enterprise single-tenant data centers in Columbus when the tenant carries investment-grade credit and the lease structure is long-term NNN. With the 10-year Treasury in the 4.3 percent range in 2026, life company spreads for credit-tenant NNN assets in this program are running roughly 150 to 225 basis points over, depending on tenant credit, lease term remaining, and power redundancy quality. LTV on life company executions typically lands in the 60 to 70 percent range, with full-term interest-only available on the strongest deals and 25 to 30 year amortization more common otherwise. Prepayment is almost always yield maintenance, which borrowers need to model carefully against likely hold periods.
CMBS has been used selectively on stabilized Columbus enterprise data center assets where the tenant is creditworthy and the lease term is sufficient to clear the loan maturity with meaningful runway. CMBS spreads are running in the 200 to 300 basis point over range, with LTV reaching 65 to 75 percent on the right collateral. Lenders in this channel generally prefer balance sheet structures given the technical complexity of the collateral, so CMBS is a secondary rather than first-call execution for most Columbus enterprise data center deals. Regional banks including Huntington National Bank and Fifth Third Bank are competitive on smaller facilities, particularly those in the colocation or edge computing subset, where their Ohio market knowledge and existing banking relationships with enterprise tenants provide a structural advantage. Bank LTV is typically 65 to 70 percent with pricing tied to SOFR-based floating structures or fixed-rate alternatives where appetite exists.
For transitional or lease-up enterprise facilities, specialty data center debt funds fill the gap that banks and life companies leave. Bridge pricing in this program is running SOFR plus 300 to 500 basis points, with SOFR currently near 3.6 percent, which is meaningful carry cost during a lease stabilization period. Sponsors should be deliberate about bridge-to-permanent strategy before closing transitional debt, as refinance risk on single-purpose assets is real if lease-up extends beyond initial projections.
Underwriting Criteria That Matter in Columbus
Tenant credit is the dominant underwriting variable in enterprise single-tenant data center financing, and Columbus lenders are not making exceptions. Life companies and CMBS lenders want to see investment-grade or near-investment-grade tenants with stable long-term financials. Government agency tenants and regulated financial institutions occupy the top of the credit stack. Healthcare systems affiliated with major national operators are viewed favorably. Unrated or private enterprise tenants require additional structural support including reserves, letters of credit, or parent guarantees to achieve competitive pricing.
Lenders scrutinize power infrastructure heavily in this market. Ohio's grid has supported significant data center load, but power availability timelines have extended as hyperscale demand competes for utility capacity, particularly in New Albany and surrounding areas. Enterprise single-tenant deals need to demonstrate delivered and contracted power, not simply planned capacity. Redundancy configurations including N+1 or 2N power and cooling architecture are baseline expectations, and lenders increasingly require third-party technical due diligence reports from qualified data center engineers before closing.
Alternative-use analysis is unavoidable given the single-purpose nature of these assets. Lenders will stress-test what happens if the enterprise tenant vacates at lease expiration and the market for a replacement single-tenant operator is limited. Strong Columbus market fundamentals help this analysis, but sponsors need to be prepared to discuss re-tenanting scenarios with specificity, not generalities.
Typical Deal Profile and Timeline
A representative Columbus enterprise single-tenant data center financing in this program falls in the $10 million to $150 million range, with the most common permanent loan executions clustering between $20 million and $80 million. Sponsors lenders want to see have demonstrated experience in data center development or ownership, a clearly articulated relationship with the enterprise tenant, and ideally some track record with technically complex assets. Sale-leaseback sponsors tend to be financial institutions or corporate real estate teams monetizing owned facilities, which is a different profile than developer-sponsors seeking construction or stabilization capital.
Timeline from a signed letter of intent to closing on a permanent life company or CMBS execution is realistically 60 to 90 days assuming clean title, lease documentation, and tenant financials are in order. Technical due diligence, including engineering reports and compliance audits, is the most common source of timeline extension. Bridge loan closings through debt funds can move in 30 to 45 days for experienced sponsors, though documentation of power contracts and security compliance typically drives the schedule regardless of capital source.
Common Execution Pitfalls Specific to Columbus
The first and most common pitfall is misreading power availability as a given in the New Albany and central metro submarkets. Hyperscale campus development has created material utility queue backlogs with AEP Ohio, and enterprise single-tenant projects that have not secured contracted power capacity before approaching lenders will face significant friction in the financing process. Lenders are not willing to advance permanent capital against power that is projected rather than committed.
Second, sponsors underestimate the weight lenders place on lease structure details. A 10 to 15 year NNN lease tied to mission-critical infrastructure is the ideal financing profile, but leases with early termination options, co-tenancy provisions, or annual renewal mechanics rather than a hard term will be haircut significantly in underwriting or declined outright by life company lenders. Getting lease counsel involved before the financing process begins is worth the time.
Third, Ohio's HB 9 tax abatement on data center equipment is a selling point in the leasing market, but sponsors who have structured their deals around abatement benefits that are property-specific or tenant-specific need to clarify exactly how those benefits transfer or survive in a sale-leaseback or refinance scenario. Lenders will ask, and vague answers create unnecessary delays.
Fourth, alternative-use risk conversations are often avoided until lenders raise them formally in credit committee. Sponsors who come prepared with a realistic re-tenanting narrative supported by Columbus market absorption data, including the demonstrated demand from financial services and healthcare tenants in the market, will move through credit approval more efficiently than those who treat the question as hypothetical.
