Credit tenant lease financing

How a CTL loan differs from a mortgage

A conventional lender values the building, then lends a share of that value. A CTL lender values the lease: a stream of rent from a rated company. It discounts that stream at a rate tied to the tenant’s credit, adds structure so the rent goes straight to the lender, and lends close to its present value. The building is still collateral, but it is the fallback, not the basis.

The result is a loan that behaves like a corporate bond secured by real estate: long, fixed-rate, fully amortizing, with make-whole prepayment.

Worked example: CTL vs conventional sizing

Illustration only. Rates, cap rates and ratios are assumptions.

A distribution building is leased to a rated tenant for 20 more years at $1,000,000 a year, absolute net.

	Conventional mortgage	CTL loan
Basis	Value at an assumed 6.50% cap rate: $15,385,000	Present value of the lease rent
Sizing rule	Assumed 65% LTV	Assumed 1.00x coverage over a 20-year amortization at 6.00%
Loan	$10,000,000	about $11,632,000
Balloon at year 20	Large, unless refinanced earlier	None
Amortization	Partial, with a balloon at maturity	Fully amortizing over the lease

At an assumed 1.05x coverage instead, the CTL loan would be about $11,078,000. The CTL structure lends more here because the rent fully retires the loan. It also leaves almost no room to refinance out cash later, because the loan tracks the lease, not the building’s value. Check the payment and paydown in the amortization schedule calculator and the value side in the cap rate calculator.

Which leases fit

Lease feature	Fits CTL	Needs a fix
Tenant credit	Investment-grade, or guaranteed by a rated parent	Unrated: conventional mortgage instead
Rent obligation	Absolute net, rent due regardless of casualty	Rent abates after casualty: lease enhancement insurance
Repairs and roof	Tenant responsible for everything	Landlord roof and structure: reserve or insurance
Termination rights	None in the primary term	Early termination or go-dark rights: usually disqualifying
Term	Long enough to retire the loan	Short remaining term: smaller loan or conventional

Costs and timeline

• Rate: fixed, priced as a spread to the matching Treasury that tracks the tenant’s own borrowing cost.
• Placement fee to the arranger, plus investor and lender counsel.
• Lease enhancement or residual value insurance when the lease is not fully bondable.
• Timing: the lease review, the tenant’s estoppel and the rent direction letter set the pace.

Prepayment

Expect make-whole yield maintenance or defeasance. Investors buy CTL notes for a long fixed cash flow and will charge for losing it. If you may sell the building before the lease ends, structure the loan to be assumable by a buyer.

What CTL lenders check

1. The tenant’s rating and outlook, and any parent guaranty.
2. Every lease clause that could stop the rent: casualty, condemnation, repair obligations, offsets, termination and assignment.
3. The tenant’s estoppel and acknowledgment that it will pay rent directly to the lender.
4. The building’s dark value, what it would be worth empty, as the fallback.
5. Title, survey and environmental reports on the real estate.

Common deal killers

• Unrated or weak tenant credit. The structure only works when the tenant’s credit carries the loan.
• Landlord obligations in the lease that cannot be insured or reserved for.
• Termination, co-tenancy or go-dark rights inside the primary term.
• A tenant that will not sign the estoppel or direct rent to the lender.

Where it wins and where it loses

CTL financing wins on single-tenant net lease property with a rated tenant and a long lease, and on build-to-suits where the lease is signed before construction. It loses to a life company loan or a CMBS conduit loan when the owner wants a balloon structure with future cash-out potential, and to a bank loan when the tenant is unrated. If the building sits on leased land, read leasehold financing as well.
