How to Actually Underwrite a Sale-Leaseback (Not Just Apply a Cap Rate)

TL;DR

A sale-leaseback is where an operating company sells a property it owns and simultaneously leases it back from the buyer — effectively converting owned real estate to long-term lease liability and freeing up capital for operations. For the real estate buyer, this is both a credit investment and a real estate investment. The tenant and the seller are the same party, which changes the diligence profile materially: you're evaluating (1) the business's ability to pay rent for the lease term, (2) whether the rent-to-sales ratio is sustainable, (3) whether the property is worth the purchase price independent of the tenant, and (4) what happens if the tenant fails. This post walks through a systematic framework for each element.

What a Sale-Leaseback Is

An operating company owns its real estate. A real estate investor (the buyer) purchases the property for cash and simultaneously enters into a long-term lease agreement with the operating company — now the tenant — for continued use of the property. The operating company keeps the business running; the real estate investor owns a commercial real estate asset with a long-term lease in place.

Why the operating company does it:

• Converts illiquid real estate equity into operating cash
• Removes debt from the balance sheet (if the property was encumbered)
• Simplifies focus on core operations
• Tax treatment benefits in certain structures

Why the real estate investor does it:

• Long-term lease with specific rent economics
• Properties often sold at discount to intrinsic value (sellers motivated by other factors)
• Credit exposure to an identified business
• Potentially higher cap rate than open-market comparable properties

The Dual Analytical Challenge

Traditional commercial real estate underwriting focuses on the property, assuming the tenant is a given. Traditional credit underwriting focuses on the tenant's business, assuming the collateral is given.

Sale-leaseback underwriting is both. The tenant is the seller, and the seller's willingness to sell at a given price is often driven by urgent capital needs — which correlates with credit pressure. The transaction's economics depend on:

1. Credit of the tenant-seller — can they pay rent for 20 years?
2. Lease economics — is the agreed rent sustainable relative to their operations?
3. Property fundamentals — independent of the tenant, what's the property worth?
4. Exit strategy — if the tenant fails, what do you do with the property?

Each of these is discussed below.

1. Credit Underwriting

Start here. The tenant's creditworthiness drives everything else in a sale-leaseback.

For publicly-traded tenants

• Current financial statements: 10-K, 10-Q, quarterly earnings releases
• Credit rating: S&P, Moody's, Fitch — verify current rating and outlook
• Leverage: debt-to-EBITDA, interest coverage, debt maturity profile
• Operating trajectory: revenue growth, margin trends, market position
• Capital allocation history: share buybacks, dividends, acquisitions

For private tenants

Harder to underwrite because less public information is available. Required diligence:

• Audited financial statements for 3+ years minimum — historical P&L, balance sheet, cash flow
• Banking relationships and debt facilities (loan agreements if available)
• Ownership structure — who owns the company, any investor influence
• Industry position and competitive landscape
• Management team quality and track record

For private tenants, it's often useful to think about:

• If this company went public tomorrow, what rating would they get?
• Would a bank lending facility be available at commercial terms?
• Is this a business with stable, predictable cash flow, or is it cyclical?

Credit red flags specific to sale-leaseback sellers

The seller is often motivated by capital needs that correlate with credit pressure:

• Recent covenant violations or breaches
• Upcoming debt maturities that need refinancing
• Extended negative cash flow
• Large capital expenditures underway
• Leveraged buyout or other transformative transaction

A sale-leaseback financing is sometimes effectively a last-resort capital source. Not always — but the possibility warrants specific questions about the seller's alternative capital options.

2. Lease Economics: Rent-to-Sales Analysis

The lease economics have to work for the tenant to keep paying over the long term. The most important metric: rent-to-sales ratio.

The Basics

Rent-to-sales = annual rent / annual revenue of the business operating in the property

Different categories have different sustainable ratios:

• Restaurant (sit-down): 6-9% rent-to-sales typical; above 10% is distressed
• QSR / fast-casual: 4-8% typical
• Retail (varies): 5-12% typical
• Industrial / warehouse: 2-5% typical
• Office (single-user): 8-15% typical
• Healthcare (medical office, urgent care): 6-12% typical

Above the typical range = the tenant is paying above-market rent and may struggle. Below the typical range = the tenant is paying below-market rent, which is unsustainable from the landlord side (the tenant can renew at below-market economics).

The Realistic Version

"Sales" and "rent" aren't always what they appear. For a rent-to-sales analysis:

• Use the location's specific sales, not the company's overall sales — if the company operates many locations, only the subject location's sales matter
• Use the sustained rent over the lease term, not just Year 1 — escalations matter
• Net sales, not gross; include any applicable concessions
• Compare to current market norms for the specific property type and location

The Stress Test

Model a downside scenario: what if the location's sales decline 20-30% over the lease term? Does the rent still make sense? For most healthy businesses, a 20% sales decline would be absorbable; a 30% decline would be material.

Key Takeaway: a sale-leaseback rent that's 10-15% of the location's current sales is dangerous — even a modest sales decline could put the tenant in payment distress.

3. Property Fundamentals

Independent of the tenant, what's the property worth if you had to sell it or re-tenant it tomorrow?

Appraisal-grade analysis

• Comparable sales: recent transactions of similar property types in the area
• Comparable leases: what do similar properties lease for in the market?
• Replacement cost: what would it cost to replicate the property today?
• Physical inspection: condition, age, major systems, deferred maintenance

The specific sale-leaseback question

If the tenant vacated, could I re-tenant at or above the current rent?

This is the reversion question that determines the downside. For most single-tenant net lease properties:

• Standardized, highly re-tenantable buildings (QSR, drug stores, auto parts, big-box retail): replacement tenancy is often available at similar economics
• Specialized buildings (industrial with specialized equipment, medical office with specific build-out, restaurant with elaborate fit-out): replacement tenancy may be at materially lower rent
• Build-to-suit for a specific tenant (unique floor plate, specialized features): re-tenantability may be very limited

Location quality

A great location with a mediocre tenant is generally safer than a mediocre location with a great tenant. Sale-leaseback due diligence should include location analysis independent of the specific tenant:

• Trade area demographics
• Traffic counts and visibility
• Competing uses nearby
• Market trends

4. Lease Structure Negotiation

In most sale-leaseback transactions, the lease terms are part of the negotiation. The buyer has meaningful influence on:

Typical Buyer-Favorable Terms

• Long initial term (15-20+ years) for stability
• Corporate guaranty (if the operating entity is a subsidiary of a larger corporation)
• Personal guaranty from principals (if privately held)
• Fixed or CPI-based rent escalations with reasonable rates
• Limited tenant termination rights (no outs mid-term)
• Assignment restrictions requiring landlord consent
• Specific operating covenants (continuous operations, no dark store)

Typical Tenant-Favorable Terms

• Right to early termination with notice (sometimes with buyout)
• Right to freely assign the lease
• Limited landlord consent requirements on property alterations
• Flexible use provisions (operating flexibility)
• Personal guaranty burn-off (guaranty expires after a period)

What to negotiate for: the longest, tightest, most credit-enhancing structure the tenant will agree to. The tenant has leverage because they're the seller — but so does the buyer, because the tenant wants the cash.

5. Exit Strategy

A long hold is not the same as the buyer's intent. Many sale-leasebacks are bought with a 5-7 year hold expectation, then exited. Think through the exit:

If you plan to sell:

• Will the lease structure hold value in the resale market? Long-term leases with investment-grade credit sell easily; shorter leases or weaker credit sell wider.
• What cap rate will the property trade at when you exit? Build this into your pro forma.

If you plan to refinance:

• Will a life insurance company or CMBS lender refinance? Credit and lease term both matter.
• What loan terms will you get? 75% LTV at 5% coupon is very different from 60% LTV at 7%.

If the tenant fails:

• Can you re-tenant at or above current rent?
• Can you sell the property even without a replacement tenant?
• Worst case: how long does it take to stabilize back to income?

The Purchase Price

The "right" price on a sale-leaseback accounts for:

Cap rate = Annual rent / Purchase price

Setting a target cap rate integrates all the factors above:

• Strong credit + long term + good property + reasonable rent = tight cap rate (7-8% for core investment-grade deals)
• Mediocre credit + short term or weak property = wider cap rate (9-11%)
• Weak credit + any issues = significantly wider cap rate (11-15%+)

The point where you walk away: if the deal requires a cap rate meaningfully below market (say 5-6% on mediocre credit) to justify the price the seller wants, you're paying for optimism, not underwriting.

A Checklist

Before closing a sale-leaseback:

1. Credit analysis complete — current financials, ratings, capital structure understood
2. Rent-to-sales reasonable — within sustainable range for the property type
3. Property fundamentals solid — independent of tenant, the property has value
4. Lease structure negotiated — long term, strong guarantor, appropriate covenants
5. Exit strategy defined — clear view of how and when you exit
6. Price fits all five — cap rate reflects the actual risk-adjusted return expected

If any of these five is weak, consider walking away. The sale-leaseback market is active enough that you don't need to force a weak deal.

The Bottom Line

A sale-leaseback is one of the more interesting opportunities in commercial real estate investing — you can identify assets at below-market prices from motivated sellers while securing long-term lease income from operating companies. But the transaction requires both credit underwriting and real estate underwriting, and getting either one wrong produces bad outcomes.

For a broker representing either side of a sale-leaseback, running through all five elements above — with real data, not assumptions — is the difference between closing a good deal and closing an expensive mistake.
