Rental property is both real property and personal property at the same time. The land and the building sitting on it are real property, while movable items the landlord supplies inside the unit — refrigerators, stoves, washing machines, window air conditioners, freestanding furniture — are tangible personal property. That split is not a technicality. It controls how fast you can depreciate each asset, how gain is taxed when you sell, and whether you can defer tax by exchanging the property for another.
The Land and Building Are Real Property
Real property is the fixed, immovable part of the rental. It covers the land itself, the foundation, walls, roof, plumbing, electrical wiring, and built-in systems like central heating. It also extends down to the soil and minerals beneath the surface and up into the airspace within the property’s boundaries. Legally, the land and the structure attached to it are treated as a single unit.
Because real property cannot be picked up and carried away, ownership generally transfers through a written deed that is recorded in public records. That recording creates a chain of title anyone can verify, which protects both buyers and sellers.
Movable Items Inside the Unit Are Personal Property
Not everything the landlord owns at the property is real property. Appliances, window units, carpeting, and freestanding furniture are tangible personal property. The tax code calls these Section 1245 property — depreciable assets that are not part of the building’s structure.1Office of the Law Revision Counsel. 26 U.S. Code 1245 – Gain From Dispositions of Certain Depreciable Property
A built-in dishwasher that is bolted to cabinetry behaves differently in the tax code than a portable one on wheels, even though both wash dishes. The first has effectively become part of the building; the second has not.
How to Tell a Fixture From Personal Property
The line between the two categories is not always obvious, and courts generally look at three factors when deciding whether a specific item has become a fixture (and therefore real property) or remains personal property.
Attachment. How firmly is the item physically connected to the building? Something hardwired, plumbed in, or bolted down leans toward real property. Something that unplugs and rolls out the door does not.
Adaptation. Does the item serve the building itself or a separate purpose? A boiler that heats the structure is part of the real property. A standalone space heater is personal property.
Intent. Did the person who installed the item mean for it to become a permanent part of the building? Custom shelving built into a closet suggests permanence. A freestanding bookcase set against the same wall does not.
Getting the classification right matters because the two categories follow entirely different depreciation schedules, and misclassifying an item leads to incorrect tax filings.
Why the Classification Changes Your Taxes
Buildings wear out over time, so the IRS lets you deduct a share of the building’s cost each year through depreciation. The land itself is never depreciated. Only the structure, its components, and the personal property inside it can be written off, and each category has its own recovery period.
Depreciation of the Building
Under the general depreciation system, residential rental property is depreciated over 27.5 years using the straight-line method, so the deduction is roughly the same dollar amount each year. Nonresidential (commercial) real property is depreciated over 39 years. If you are required to use the alternative depreciation system — for example, because the property is used in a tax-exempt bond-financed project — the recovery period stretches to 30 years for residential and 40 years for commercial.2Internal Revenue Service. Publication 946, How To Depreciate Property
Depreciation of Appliances and Furniture
Appliances like stoves and refrigerators, along with carpeting and furniture placed in a residential rental, are 5-year property under the general depreciation system.3Internal Revenue Service. Publication 527 (2025), Residential Rental Property That much shorter timeline lets you recover the cost of those items far faster than the building itself.
Under the One, Big, Beautiful Bill signed into law in 2025, qualified personal property acquired after January 19, 2025 is eligible for a permanent 100-percent bonus depreciation deduction, meaning the entire cost can be written off in the first year the item is placed in service.4Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One, Big, Beautiful Bill That bonus applies to items like appliances and furniture, not to the building structure itself.
So the classification question is really a timing question. The washing machine in Unit 2 can be written off this year. The building housing Unit 2 is written off over nearly three decades.
Why the Classification Changes What Happens When You Sell
The real-versus-personal split also drives two things that matter at the end of ownership: whether you can defer gain through an exchange, and how the gain is taxed if you can’t.
Section 1031 Exchanges Apply Only to Real Property
Under Section 1031, you can swap one investment property for another of like kind and defer capital gains tax on the sale. This works only for real property.5Office of the Law Revision Counsel. 26 U.S. Code 1031 – Exchange of Real Property Held for Productive Use in a Trade or Business or for Investment A rental house can be exchanged for an office building, or a warehouse for an apartment complex, and the gain deferred.
Before 2018, like-kind exchanges also covered personal property. The Tax Cuts and Jobs Act eliminated that option, and Section 1031 now applies exclusively to real property.6Internal Revenue Service. Like-Kind Exchanges – Real Estate Tax Tips When you sell or replace appliances, furniture, or other personal property in a rental, any gain is taxable immediately, with no deferral mechanism available. One more boundary worth noting: U.S. real property cannot be exchanged for real property located outside the United States. The two are not considered like kind.5Office of the Law Revision Counsel. 26 U.S. Code 1031 – Exchange of Real Property Held for Productive Use in a Trade or Business or for Investment
Depreciation Recapture Works Differently for Each
If you sell outright, the IRS takes back some of the depreciation benefit you claimed, and it does so differently for the two categories.
For the building (Section 1250), the depreciation you claimed is recaptured by taxing that portion of your gain at a maximum rate of 25 percent, rather than at the lower long-term capital gains rate that applies to the rest of your profit. This is called unrecaptured Section 1250 gain. Any gain above the total depreciation claimed is taxed at regular capital gains rates.7Office of the Law Revision Counsel. 26 USC 1250 – Gain From Dispositions of Certain Depreciable Realty
For personal property (Section 1245), depreciation recapture is taxed as ordinary income up to the amount of depreciation previously deducted.1Office of the Law Revision Counsel. 26 U.S. Code 1245 – Gain From Dispositions of Certain Depreciable Property Because appliances and furniture are often fully depreciated to zero, most or all of the sale proceeds for those items can land at your ordinary income rate rather than at capital gains rates. The fast write-off is generous upfront, but it has a cost at the back end.
A Second Split Within Real Property: Residential or Commercial
Within the real property category, there is one more line to be aware of. Under federal tax law, a building qualifies as residential rental property only if 80 percent or more of its gross rental income comes from dwelling units — houses or apartments used as living space.8Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System A dwelling unit does not include a hotel or motel room if more than half of the units in the building are rented on a short-term, transient basis.
Fall below the 80 percent threshold — a mixed-use building where ground-floor retail generates more than 20 percent of total rental income is the typical example — and the property is classified as nonresidential real property. That shifts the depreciation schedule from 27.5 to 39 years and can affect how lease terms are structured.
The residential-versus-commercial line also shapes tenant protections. Residential tenants generally benefit from an implied warranty of habitability, meaning landlords must keep the property in safe, livable condition. Commercial tenants typically negotiate their own lease terms with fewer built-in legal protections, on the assumption that business parties have relatively equal bargaining power. These protections vary by jurisdiction, so landlords and tenants should check local rules.
