Which NNN properties offer the most bonus depreciation? The honest answer depends less on the tenant’s name than on three facts about the deal: whether the buyer owns the building, which improvements and equipment actually convey with the property, and whether the property meets any special IRS classification rules. This ranking orders common NNN property types by how much of the buyer’s depreciable basis typically falls into short recovery classes, and explains the conditions behind each.
The rules in brief. Under the One Big Beautiful Bill Act, 100% bonus depreciation is permanent for qualified property acquired after January 19, 2025. Qualified property generally means property with a recovery period of 20 years or less: 5- and 7-year personal property and 15-year land improvements and qualified improvement property. A 39-year commercial building does not qualify, and land is never depreciable. Percentages quoted in marketing are often based on total price including land, or include equipment the tenant owns; neither belongs in the buyer’s estimate.
The Ranking
| Rank | Property Type | Why It Can Rank High | Main Conditions |
|---|---|---|---|
| 1 | Gas stations and convenience stores that qualify as retail motor fuels outlets | The whole building can be 15-year property, so building and site work can be bonus eligible | IRS tests: at least half of gross revenue from fuel, at least half of floor space devoted to fuel sales, or a building of 1,400 sq ft or less; buyer must own the building; fuel equipment is often the operator’s |
| 2 | Car washes (fee simple, with equipment conveyed) | Wash equipment is 5- or 7-year personal property, and site work is extensive | Only if the buyer acquires the equipment; in many sale-leasebacks the operator keeps it |
| 3 | Pad-site restaurants and auto service (fee simple) | Paving, drive-through lanes, curbing, lighting and landscaping are 15-year land improvements | Kitchen equipment, lifts and fixtures are usually the tenant’s; the building is 39-year |
| 4 | Medical outpatient buildings (fee simple) | Specialized electrical, plumbing and buildout may include shorter-life components | Medical equipment is usually the tenant’s; results depend heavily on the study |
| 5 | Standard retail boxes | Site improvements and some interior components | Most basis is the 39-year building |
| Not applicable | Ground leases (land only) | None | Land cannot be depreciated; the tenant owns and depreciates the building |
Order reflects typical structure, not a guarantee. Results depend on the purchase allocation, what conveys, an engineering-based cost segregation study and the investor’s tax situation.

Depreciation Rank Is Not Credit Rank
A property type’s depreciation profile says nothing about whether the tenant will pay rent. Some of the tenants most associated with depreciation-heavy property types are not investment grade: many gas stations and car washes are leased to private or franchised operators, and quick service brands such as Burger King (BB+) and Taco Bell (parent Yum! Brands, BB+/Ba2) are rated below investment grade at the parent level, with most leases signed by franchisees. Others, such as 7-Eleven (A-/Baa2), carry investment grade parent ratings. Check every tenant in our tenant ratings database and confirm the tenant entity in the lease before relying on a rating.
Combining a 1031 Exchange With Bonus Depreciation
Investors selling appreciated property often pair a 1031 exchange with bonus depreciation on the replacement property. The exchange defers gain on the relinquished real property. Note, however, that the replacement property’s depreciable basis generally carries over from the relinquished property, so bonus depreciation applies mainly to any additional basis (for example, new cash or debt) and to newly acquired qualifying components; and only real property qualifies for a 1031 exchange, so personal property sold with a property is not deferred. Model both with a tax adviser before relying on the combination.
Underwriting Considerations
Study cost versus benefit. Cost segregation studies often cost from about $5,000 to more than $15,000 depending on property size and complexity. Whether one pays off depends on the depreciable basis that can be reclassified (excluding land and tenant-owned assets), the investor’s tax rate, state conformity to federal bonus depreciation, and whether the deductions can be used.
Using the deduction. NNN rental activity is generally passive. Losses offset passive income first; excess losses are suspended until there is passive income or the property is sold, unless the investor qualifies as a real estate professional and materially participates in the rental activity. A large first-year deduction is only a first-year tax saving if it can be used.
Electing out. Bonus depreciation is the default. A taxpayer can elect out, but the election generally applies to all qualified property in the same class placed in service in that tax year, not property by property. Plan the election with a tax adviser.
Recapture. Bonus depreciation increases recapture on a taxable sale, much of it at ordinary income rates. Recapture on real property can be deferred through a 1031 exchange into real property; recapture on personal property generally cannot, because personal property is no longer eligible for 1031 treatment.
