The short answer: underwrite four separate things—the physical site, the actual lease and guarantor, the operating location, and the property’s next use. A quoted cap rate describes in-place income; it is not a substitute for any of these tests.
1. Identify exactly what you own
Start with title, survey, site plan and lease exhibits. An investor may buy fee-simple land and building subject to a lease, the land under a tenant-owned building, or a different interest altogether. The economics and the improvements remaining at expiration can differ considerably.
Separate the parcel from the restaurant concept. An attractive drive-thru might occupy a constrained lot with difficult access; an unremarkable building may sit on a hard corner with several plausible future uses. Neither the menu nor the logo appears in your deed.
- Confirm the legal parcel, easements and access rights.
- Map drive-thru stacking, parking, deliveries and pedestrian conflicts.
- Ask what the land and improvements could support if the current operator vacates.
2. Read the lease and identify the rent obligor
A national brand can be operated by a franchisee; the brand on the building is not necessarily the party signing or guaranteeing the lease. Obtain the executed lease, amendments, guaranty and an entity chart. Then confirm whose balance sheet supports the promise to pay.
Review remaining term, rent steps, options, termination rights, assignment, maintenance, casualty and restoration. The label “NNN” does not override the actual contract language. A renewal option belongs to the party named in the lease; your exit model should not assume exercise.
- Who is the tenant and who, if anyone, guarantees it?
- Which costs stay with the owner despite a net-lease label?
- What happens to improvements, signage and equipment at surrender?
3. Test the location, not just the chain
Request property-specific sales information when available and permitted, then compare rent to a supportable view of the location's economics. Brand-wide sales averages do not establish whether this particular restaurant can pay this particular rent. If unit-level sales are unavailable, treat that as a visibility limit—not a blank to fill with a confident guess.
The FTC's Franchise Disclosure Document guidance is useful context for understanding franchise systems, but an owner buying leased real estate is not automatically entitled to the operator's private FDD or unit financials. Request information through the seller, tenant and appropriate advisers.
4. Underwrite a dark-store exit
Set a second valuation case in which the tenant closes and rent stops. Estimate downtime, commissions, concessions, re-tenanting costs, building conversion and any demolition. Check zoning and whether the drive-thru approval is transferable or must be re-entitled. A site visit is a starting point, not a replacement for written municipal confirmation.
A useful deal memo shows both the in-place lease value and a supportable alternative-use value. A bargain purchase price cannot cure a land parcel with no feasible next use, but a flexible corner can create an exit path if the restaurant concept changes.
Investor test: If this tenant left tomorrow, who would want the site, what would they pay, and what would it cost to get there?
