How to Finance a Modular Data Center
Lenders finance a modular data center mostly by lending against the GPU servers inside it, repaid from a contracted offtake. The module, power gear and land are harder to value, and they can become fixtures claimed by whoever owns or lends against the land.
The deal turns on four things: keeping the equipment personal property, a site lease that outlasts the loan, a power contract that does too, and insurance that names the lender.
What gets financed in a modular site
A modular site has four layers of cost, and lenders treat each one differently. The case for modular data centers is speed and access to power. The financing question is which layer can carry a loan.
| Layer | What it includes | Resale market | How lenders treat it |
|---|---|---|---|
| GPU servers | 8-GPU servers, networking, storage | Deep, priced by model and age | Primary collateral, sized against the offtake |
| The module | Enclosure, cooling, power distribution, fire suppression | Thin, often site-specific | Lower advance, priced on removal cost and resale |
| Power gear | Transformers, switchgear, generators | Active, with long lead times new | Can belong to the landlord, utility or power developer |
| The site | Land, pad, access road, utility easements | Real estate | Usually leased, so the lender needs the landowner's consent |
The servers are most of the money. A megawatt of current GPU servers costs more than the building around it, and a prefabricated facility costs about the same per megawatt as one built on site. The numbers are in modular data center cost per MW.
The module is the hardest layer to value. The one public bankruptcy sale of used containers is in what a used module is worth.
Equipment or fixture
A fixture is equipment so attached to land that real estate law claims it. Article 9 of the Uniform Commercial Code (UCC), the law that governs liens on equipment, defines fixtures as goods so related to particular real property that an interest in them arises under real property law. [1]Uniform Commercial Code Section 9-102(a)(41): definition of fixtureshttps://www.law.cornell.edu/ucc/9/9-102 Once equipment is a fixture, the landowner's mortgage lender can outrank the equipment lender.
The test courts use
The classic test comes from Teaff v. Hewitt, decided by the Ohio Supreme Court in 1853: actual annexation to the land, application to the use of the land, and intent to make a permanent addition. [2]Teaff v. Hewitt, 1 Ohio St. 511 (Ohio 1853), via the Caselaw Access Projecthttps://static.case.law/ohio-st/1/html/0439-01.html Ohio courts still apply it. [3]Fifth Third Mortgage Corp. v. Johnson, 2011-Ohio-6778 (Ohio Ct. App. December 2011), applying the Teaff testhttps://www.supremecourt.ohio.gov/rod/docs/pdf/5/2011/2011-ohio-6778.pdf
In Teaff, a woolen mill's carding machines, spinning machines and power looms, held in place by cleats and moved around the floor at will, were chattels, and judgment creditors seized them. The steam engine and boilers, bolted to timbers on stone foundations laid in the earth, were fixtures and went to the mortgage lender. [2]Teaff v. Hewitt, 1 Ohio St. 511 (Ohio 1853), via the Caselaw Access Projecthttps://static.case.law/ohio-st/1/html/0439-01.html
A modular site maps onto that mill. GPU servers in racks are the looms. A transformer on a poured pad, wired to the utility, is the engine. The module sits in between, and how it is set, plumbed and leased decides which side it lands on.
Who wins a fixture fight
The default rule favors the real estate side. A security interest in fixtures loses to the owner or mortgagee of the land unless an exception applies. [4]Uniform Commercial Code Section 9-334: priority of security interests in fixtureshttps://www.law.cornell.edu/ucc/9/9-334
| Rule | Equipment lender wins if | Fit for a modular site |
|---|---|---|
| 9-334(c) | Never by default: the land side wins | The starting point |
| 9-334(e)(1) | Its fixture filing is recorded before the competing real estate interest | Works on a new site. An existing mortgage already beats it |
| 9-334(e)(2) | The goods are readily removable factory or office machines, perfected before they became fixtures | Strongest for servers, arguable for a skid-mounted module |
| 9-334(f) | The owner or mortgagee consents or disclaims in a signed record, or the debtor has a right to remove | The cleanest fix: a landlord and mortgagee waiver |
| 9-334(h) | The goods became fixtures after a recorded construction loan finished building, or that lender signs a waiver | A risk when the landowner is still building |
A fixture filing is a UCC-1, the public notice of a lien, recorded in the county land records where the site sits, the office that records mortgages. [5]Uniform Commercial Code Section 9-501(a)(1)(B): where to file a fixture filinghttps://www.law.cornell.edu/ucc/9/9-501 It sits on top of the usual UCC-1 filed in the borrower's state. Searching those county records before funding shows any mortgage or construction loan that already outranks the lender.
Taking the equipment out
A lender with fixture priority may remove the collateral after default. It must pay to repair physical damage the removal causes, but owes nothing for the lost value of the land. [6]Uniform Commercial Code Section 9-604: removal of fixtures after defaulthttps://www.law.cornell.edu/ucc/9/9-604 The landowner can refuse access until the lender gives adequate assurance it will pay.
Cutting a module off its pad, capping the cooling loop and hiring a crane are the lender's bill, set against what the module sells for.
Who controls the site
A lender can only recover equipment it can reach. When the operator leases the land or a pad from a power developer, a landowner or a mining host, the loan depends on a contract the lender is not party to.
- Lease term. The ground lease, extensions included, runs past the loan's final payment plus the months a recovery takes.
- Landlord waiver. The landowner disclaims any interest in the equipment as fixtures and waives statutory landlord liens.
- Removal right. The ground lease lets the operator remove its equipment. That right gives the lender priority over the landowner under 9-334(f), though not over a mortgagee the lease does not bind.
- Mortgagee waiver. If the land is mortgaged, the landowner's lender signs too. A landlord waiver alone does not bind it.
- Access agreement. Notice of lease default, a cure period, and the right to enter, operate or remove for a set number of days.
- Assignment. The right to assign the lease to a replacement operator, which keeps a running site worth more than a parted-out one.
A GPU lender negotiates the same access and removal terms with a colocation provider. The colocation contract side looks different: a license to occupy space instead of a lease of land.
The power contract
The offtake pays only while the GPUs run, and the GPUs run only while the power contract does. A three-year GPU loan on a site with a two-year power agreement has a refinancing problem built in.
Replacing power gear is slow. As of 2026, pad-mounted transformers carry lead times of 68 to 113 weeks. [7]CRE Daily, "Data Center Construction Costs Jump 21% Since 2024," on the Cushman & Wakefield 2026 guide (August 27, 2026)https://www.credaily.com/briefs/data-center-construction-costs-jump-21-since-2024/ A failed transformer with no spare can idle a site for more than a year.
| Power arrangement | Main risk to debt service |
|---|---|
| Utility service at the site | Tariff changes and curtailment rules for large loads |
| Power agreement with a nearby plant | Term shorter than the loan, plant outages |
| Operator-owned on-site generation | Fuel supply, air permits, a single point of failure |
Sites powered by their own generators carry plant and fuel risk of their own, covered in behind-the-meter GPU deployments.
Insurance and the loss payee
A loss payee is the party an insurer pays directly when insured property is destroyed. Lenders require it on the GPUs' property insurance so that fire proceeds repay the loan before they reach the borrower's operating account. The module and the power gear sit on their owners' policies, and the lender asks for evidence of that cover. Who insures which layer is covered in insuring modular data centers.
Which structure fits
Three structures cover most modular financings, and the choice follows who owns each layer at the end.
| Structure | Who owns the GPUs | Fits | Watch for |
|---|---|---|---|
| Equipment loan | Operator, lender holds a lien | Operators with equity and an offtake | Fixture priority on anything bolted down |
| Lease | Lessor, until any buyout | Operators short on equity | Recharacterization as a loan, so file a precautionary UCC-1 |
| Sale-leaseback | Investors who bought and leased back | Freeing cash from equipment already bought | Many owners sharing one site and one point of failure |
NFN8 shows the last row. It had sold mining machines to more than 250 separate investors and leased them back on two- to four-year terms, paid from mining revenue. [8]TheEnergyMag, "Bitcoin Miner NFN8 Files Chapter 11 After Fire" (February 9, 2026)https://theenergymag.com/news/2026-02-09/bitcoin-nfn8-bankruptcy A fire at its Crystal City, Texas facility cut the revenue that paid all of them by as much as half, and NFN8 filed for Chapter 11 in February 2026.

Frequently Asked Questions
How do you finance a modular data center?
Mostly by lending against the GPU servers inside it, which have a resale market and are repaid from a contracted offtake. The module, power gear and land carry a lower advance or are financed by their owners. Before funding, the lender gets waivers from the landowner and any mortgagee, and checks that the site lease and power contract run past the loan.
Is a modular data center a fixture or equipment?
It depends on how it is attached, used and intended, under the state fixture test that dates to Teaff v. Hewitt (Ohio, 1853). GPU servers in racks are equipment. A transformer on a poured pad wired to the utility is likely a fixture, and the module sits in between.
Who wins when a GPU lender and the landowner both claim a module?
By default the landowner or its mortgage lender, under UCC 9-334(c). The equipment lender wins if it recorded a fixture filing first, if the goods are readily removable machines perfected before they became fixtures, or if the owner or mortgagee consented or disclaimed in a signed record.
What is a fixture filing?
A UCC-1 financing statement recorded in the county land records where the equipment sits, the same office that records mortgages. It puts real estate buyers and lenders on notice of the equipment lender's lien, on top of the usual UCC-1 filed in the borrower's state.
