Underwrite a single-tenant industrial building the way its income actually behaves: as a claim on one tenant's ability to keep paying, not as a generic industrial box with a lease attached.
A multi-tenant property spreads risk across many leases. A single-tenant industrial building does not. If the tenant stops paying, the income goes to zero at once, and re-leasing a large single-user building can take far longer than re-leasing a multi-tenant one. That is why credit-tenant lease (CTL) pricing tracks the guarantor's balance sheet as much as it tracks the building.
Where A Building-First Model Falls Short
A model built around the building can get the mechanics right and still miss the point of a single-tenant deal:
- It treats a rated national logistics tenant and an unrated regional operator as interchangeable inputs to the same cap rate.
- It prices the lease off comps for the building type rather than off the spread investors demand for that tenant's credit.
- It does not separate what happens if the tenant renews from what happens if the building has to be re-let cold.
- It does not connect lease structure (who pays taxes, insurance, and structural repairs) to the risk the owner is actually carrying.
What A Single-Tenant Underwrite Has To Carry
Five inputs decide a single-tenant deal. Each belongs in the model, next to the numbers it moves:
- Who is actually on the hook. The signing entity and the guarantor, including where a subsidiary or affiliate signs and the parent does not.
- How long the income is secured. Remaining term, renewal options, and any termination or co-tenancy rights that shorten it.
- How the rent moves. Fixed bumps, CPI-linked escalations, or flat rent for the term.
- Who pays for what. Taxes, insurance, and structural or roof and wall repairs under the lease. "NNN" on the flyer and the expense clauses in the lease are not always the same thing.
- The re-let case. Downtime, leasing cost and the rent a new tenant would pay for this specific building in this market, if the current one leaves.
How Titleman Fits
Send the deal with the lease, any guarantor financial information you already have, and the offering materials. Titleman underwrites from those documents rather than from public-data inference alone, and every figure in the answer carries its source. What was assumed, such as a re-let downtime or a credit spread, is kept apart from what the documents state, so your team can inspect, adjust and defend the number instead of accepting a black-box output.
Titleman does not issue a credit rating. The credit judgment stays with your team; the underwriting puts the evidence for it next to the numbers it affects.

For investment firms
Screen single-tenant industrial and CTL opportunities with the guarantor question answered up front, not discovered during diligence.
For lenders and banks
Review loan collateral where the credit of one tenant, not a diversified rent roll, secures the debt.
For developers
Underwrite build-to-suit and sale-leaseback deals where the tenant's credit largely determines what the finished asset is worth.
For advisory and brokerage teams
Test a credit-tenant industrial deal against the questions an institutional buyer's own review will ask.

FAQ
What makes single-tenant industrial NNN underwriting different?
A single-tenant industrial building has one income stream, so its value depends heavily on whether that one tenant keeps paying. The tenant's and guarantor's credit standing, not just the building's specs, drives the pricing.
What is a credit-tenant lease (CTL)?
A credit-tenant lease is a long-term net lease backed by a tenant with an investment-grade or otherwise well-documented credit profile. Its pricing behaves more like a fixed-income instrument tied to that tenant's credit than like a typical real estate cap rate.
Does Titleman rate tenant credit?
No. Titleman does not issue a credit rating. It carries the tenant and guarantor information you supply into the same underwriting as the building and the lease, and marks what was assumed, so the credit question is visible next to the numbers it affects.
What should a single-tenant industrial underwriting model flag?
Remaining lease term relative to the loan or hold period, renewal and termination options, rent escalations, who is responsible for structural and capital items, and what happens to value and re-leasing cost if the tenant vacates.
Who underwrites single-tenant industrial and credit-tenant deals?
Investment firms, lenders and banks financing net-lease industrial assets, developers building to suit, and advisory and brokerage teams evaluating credit-tenant industrial product.
