Do houses depreciate? Yes — the physical building loses value from the day it’s finished, as roofing, mechanical systems, and finishes wear out and as layouts fall behind what buyers want. But the land underneath does not depreciate, and in most U.S. markets land appreciates fast enough to more than offset the building’s decline. That’s why total property values keep climbing even as individual houses age. U.S. house prices rose 1.8 percent between the fourth quarter of 2024 and the fourth quarter of 2025.1FHFA.

How Buildings Physically Wear Out
Every component of a house has a limited useful life. Asphalt shingle roofs typically last 20 to 30 years. HVAC systems often need replacement after about 15 years. Standard carpet may hold up for only a decade under normal use. When these major systems approach the end of their lifespan, the home is worth less because the next owner will need to budget for replacements. Buyers routinely discount older homes to reflect the remaining life of these expensive components.
Structural elements like foundations and framing last far longer, but they aren’t immune. Soil shifting, water intrusion, and settling can create cracks and instability over decades. Foundation repairs range widely, from a few thousand dollars for minor crack sealing to $20,000 or more for a full replacement, and the mere presence of foundation problems can scare away buyers even when repairs are feasible. A professional structural assessment runs roughly $500 to $2,000 depending on the scope of the inspection.
Daily exposure to weather and normal household use accelerate deterioration across all systems. Repairs and routine maintenance slow the decline but cannot stop it entirely. Newer homes with integrated smart technology add another layer to the timeline: smart thermostats last roughly 10 years, security cameras 5 to 10 years, and voice-activated assistants only 3 to 5 years.
When a Home’s Design Falls Behind
A house can be in perfect physical condition and still lose value because its layout or features no longer match what buyers want. Appraisers call this functional obsolescence. A four-bedroom house with only one bathroom, a floor plan that routes traffic through a bedroom, or an undersized kitchen in a market where open-concept cooking spaces are standard — all of these reduce a home’s appeal regardless of how well the structure has been maintained.
Some functional obsolescence is curable. An outdated kitchen can be renovated. Other forms are impractical or impossible to fix, like a house built on a lot that is too small for the neighborhood or a layout that would require tearing out load-bearing walls to modernize. Buyers factor these shortcomings into their offers, and appraisers account for them when comparing a home to similar properties that have been updated. A professional appraisal typically costs a few hundred to over a thousand dollars depending on the property and location.
External Forces That Drag Value Down
Economic and environmental changes outside your property lines can reduce value even when the home itself is well maintained and functionally up to date. Local industry closures, rising crime rates, declining school quality, or a zoning shift that introduces industrial use near residential areas are all examples of economic obsolescence. A new highway ramp that increases traffic noise or the loss of nearby green space can reduce demand for an otherwise desirable location.
Environmental reclassifications create measurable losses as well. Research on New York City properties after updated flood maps were issued found that homes newly placed in a flood zone experienced an average price decrease of roughly 8 to 9 percent, with lower-priced homes losing as much as 15 to 17 percent of their value. That study reflects one market, but the principle applies broadly: when government agencies reclassify an area’s risk level, property values respond quickly and often permanently.
Market trends can also shift away from certain architectural styles or neighborhood types. These external pressures are largely outside your control, which is why monitoring local employment data, school district rankings, and planned infrastructure projects can provide early warning signals. Selling before conditions deteriorate further is sometimes the most effective way to preserve equity when a shift looks permanent.
Why Total Property Values Usually Rise
The reason real estate prices climb while houses depreciate is that you own two very different assets: the building and the land beneath it. The building is a depreciating asset that requires constant spending on upkeep. The land is a permanent asset that does not wear out, become obsolete, or get used up. That’s exactly why the IRS does not allow depreciation deductions on land.2Internal Revenue Service. Publication 946, How To Depreciate Property
Land is finite, and demand for desirable locations tends to grow over time. In many markets, that appreciation outpaces the physical decline of the structure sitting on top of it, producing net gains in total property value. Over long historical periods, nominal U.S. home prices have averaged roughly 3 to 4 percent annual growth, though after adjusting for inflation the real gain is much smaller.
The practical takeaway for a homeowner: two identical houses on two different lots can move in opposite directions over the same decade. The one in a neighborhood with rising land values may gain equity even as its roof, furnace, and kitchen age out. The one in a neighborhood losing employers and schools may lose value even after a full renovation. Maintenance protects the building side of the equation. Location determines the land side.
Depreciation as a Tax Deduction: Rental Property Only
“Depreciation” also has a specific tax meaning, and it matters if you rent your property out. Section 167 of the Internal Revenue Code allows a “reasonable allowance for the exhaustion, wear and tear” of property used in a trade or business or held to produce income.3Office of the Law Revision Counsel. 26 USC 167 – Depreciation Section 168 sets the recovery period for residential rental property at 27.5 years, using the straight-line method.4Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System
In practice, that means deducting roughly 3.636 percent of the building’s cost basis each year. If the building portion of a rental property is worth $275,000, the annual depreciation deduction is about $10,000. This is a non-cash deduction: it reduces your taxable rental income without requiring any additional spending that year.
Only the building qualifies. Land never does. When you buy a property for a single lump sum, the IRS requires you to allocate the purchase price between land and building by multiplying the total by the ratio of each component’s fair market value to the whole. If you don’t know the fair market values, the assessed values from your local property tax bill are a reasonable proxy.5Internal Revenue Service. Publication 551, Basis of Assets
Residential rental property also follows a mid-month convention, meaning the IRS treats the property as placed in service at the midpoint of the month regardless of the actual date. In the first year you only claim depreciation from that midpoint forward. IRS Publication 527 provides percentage tables that build the convention in, so you don’t need to calculate it by hand.6Internal Revenue Service. Publication 527, Residential Rental Property
One boundary matters here: you cannot depreciate a home you live in as your primary residence.3Office of the Law Revision Counsel. 26 USC 167 – Depreciation Physical depreciation still happens to your house in the real-world sense described above, but there is no annual tax deduction for it. The deduction is reserved for property used to produce income, and even then, only the building portion of the basis is eligible.
