Definition
Depreciation is a non-cash tax deduction that lets property owners recover the cost of eligible real estate improvements over time. In practice, depreciation can reduce taxable income even when the property is generating cash flow—and even when the property is increasing in market value.
What Gets Depreciated
In most real estate investments, the land is not depreciable. Depreciation generally applies to:
- Building improvements: the structure and major systems.
- Personal property: items like appliances, carpet, certain fixtures (often accelerated).
- Land improvements: parking lots, landscaping, fencing (often accelerated).
Your depreciable basis typically starts with the purchase price and closing costs, then is adjusted by allocations (land vs. improvements), capital improvements, and other accounting items.
How It’s Measured
Depreciation is usually calculated using a property’s depreciable basis divided by a prescribed recovery period under tax rules. Investors often talk about this as “annual depreciation.â€
Common formulas
- Depreciable Basis = Purchase Price + Eligible Closing Costs + Capital Improvements − Land Value (allocation)
- Annual Depreciation (simplified) = Depreciable Basis ÷ Recovery Period
- Taxable Income (simplified) = NOI − Interest − Depreciation
Why It Matters
Depreciation can materially improve after-tax cash flow by lowering taxable income. This is why two properties with identical NOI and financing can have very different investor outcomes depending on basis allocation, improvements, and tax strategy.
Investor Uses
- After-tax underwriting: estimate cash-on-cash returns after taxes, not just before-tax NOI.
- Cost segregation planning: accelerate depreciation on eligible components to increase early-year deductions.
- Renovation strategy: track capital improvements that increase basis and future depreciation.
- Hold vs. sell decisions: understand depreciation recapture exposure and timing.
Example
An investor buys a small apartment building for $5,000,000. An appraisal allocates $1,000,000 to land and $4,000,000 to improvements (depreciable). Ignoring closing costs and later capex for simplicity:
- Depreciable Basis = $5,000,000 − $1,000,000 = $4,000,000
- Annual Depreciation (simplified) = $4,000,000 ÷ 27.5 = $145,454/year
If the property produces $200,000 of NOI after interest, depreciation could reduce taxable income dramatically—even if cash flow is strong. (Actual results depend on the tax method, timing conventions, and your situation.)
Cost Segregation and Bonus Depreciation
A cost segregation study can reclassify certain components into shorter-lived categories, which can increase depreciation in the early years of ownership. When available under current law, bonus depreciation may allow a portion of qualified components to be expensed faster than straight-line schedules.
- Why investors care: accelerated deductions can improve early-year cash flow and IRR.
- Tradeoff: more front-loaded deductions can increase recapture later and may affect sale/refinance planning.
Common Pitfalls
- Depreciating land: land is generally not depreciable; allocate purchase price properly.
- Confusing cash vs. taxes: depreciation is non-cash—great for taxes, but doesn’t increase NOI.
- Missing basis adjustments: failing to track capital improvements and dispositions can distort deductions.
- Ignoring recapture: depreciation benefits often come with potential recapture at sale.
- Assuming it applies to everyone: passive activity rules, material participation, and entity structure can change outcomes.
