If you own or are considering a Clarksville, Tennessee rental property, depreciation may reduce your taxable rental income even though it does not require an annual cash payment. In most cases, residential rental property is depreciated over 27.5 years using the Modified Accelerated Cost Recovery System, or MACRS.
For a former residence converted into a rental after a PCS from Fort Campbell, the calculation generally begins with the lower of the property’s adjusted basis or fair market value on the conversion date. You then separate the building value from the land because land is not depreciable.
Depreciation can improve your after-tax return, but it does not automatically make a property cash-flow positive. You still need to evaluate rent, vacancy, management, repairs, insurance, financing, and reserves.
“Depreciation is valuable because it can reduce taxable rental income without reducing the rent deposited into your operating account. However, investors should view it as one part of a complete analysis, not as a substitute for realistic pricing, reserves, and disciplined property management.”

What is depreciation on a Clarksville rental property?
Depreciation is the federal tax method for recovering the cost of an income-producing property over its useful life. Instead of deducting the entire cost of a residential rental building in the year you purchase it, you generally deduct a portion each year.
For a typical Clarksville single-family rental, depreciation may apply to:
- The residential building
- Structural components such as the roof, HVAC system, plumbing, and wiring
- Qualified capital improvements
- Certain appliances, furniture, fencing, and other assets under separate recovery periods
Depreciation generally does not apply to:
- Land
- Mortgage principal payments
- Ordinary repairs and maintenance
- Personal-use portions of a property
The IRS Publication 527 guidance for 2025 explains that depreciation is a capital expense used to recover the cost of property placed in service for rental use.
How do you determine the depreciable basis?
Your depreciable basis is the amount assigned to the building and other qualifying assets for tax purposes. The calculation depends on how you acquired and used the property.
If you purchased the property as an investment
You generally begin with the purchase cost, then add eligible capitalized acquisition costs and improvements. You must allocate the total between:
- Land, which is not depreciable
- Building, which is depreciable
The allocation should be supported by reasonable information, such as an appraisal, closing documents, or assessed values. A simple percentage estimate may be useful for preliminary underwriting, but your tax professional should determine the appropriate allocation for your return.
If you converted your former home into a rental
This situation is common when a Fort Campbell service member receives PCS orders and keeps a Clarksville home as a long-term rental.
For property changed from personal use to rental use, the IRS generally uses the lower of:
- Your adjusted basis on the conversion date, or
- The property’s fair market value on the conversion date
After determining that amount, you allocate the basis between land and the building. Only the building portion is depreciated.
For example, assume:
- Adjusted basis at conversion: $285,000
- Fair market value at conversion: $300,000
- Building allocation: $240,000
- Land allocation: $60,000
The depreciable building basis would generally be $240,000 in this illustration because the building value is below the total property value and the allocation is supported by the applicable basis rules. Your actual calculation may differ.
How much depreciation can you claim each year?
Residential rental buildings typically use the MACRS General Depreciation System, straight-line depreciation, over 27.5 years.
Using a hypothetical depreciable building basis of $240,000:
$240,000 ÷ 27.5 = approximately $8,727 per year
The first and final years may be prorated because residential rental property uses the mid-month convention. That means the IRS treats the property as placed in service halfway through the month in which it becomes available for rent.
You generally begin depreciation when the Clarksville property is ready and available for rent, not necessarily when the first tenant signs a lease. Advertising the property, completing required repairs, and making it available for occupancy may help establish the placed-in-service date.
How does depreciation shield Fort Campbell rental income?
Rent paid by a Fort Campbell household is still rental income for federal tax purposes. Whether the tenant pays from salary, housing allowance, or another source does not make the rent tax-free.
However, depreciation may reduce the amount of that rental income that is treated as taxable income.
Consider an illustrative Montgomery County rental:
- Monthly rent: $1,800
- Annual scheduled rent: $21,600
- Annual operating expenses before debt service: $10,140
- Depreciation deduction: $8,727
- Mortgage interest: approximately $17,000 in an early loan year
The property could have taxable rental income that is significantly lower than its gross rent, and potentially show a tax loss, after operating expenses, interest, and depreciation are considered.
That tax result is separate from actual cash flow. Depreciation is a non-cash deduction. It does not pay the mortgage, fund a repair, or cover a vacancy.
Passive activity rules, income limits, active participation, at-risk rules, and your broader tax situation can restrict how much of a rental loss you may use in the current year. Ask a qualified tax professional to review your circumstances.
How do current mortgage rates affect the cash-flow math?
Depreciation does not change based on your mortgage interest rate. Your loan terms affect financing costs and cash flow, while depreciation is based primarily on depreciable basis, recovery period, and placed-in-service timing.
Freddie Mac’s Primary Mortgage Market Survey dated October 1, 2026 reported:
- 30-year fixed-rate mortgage: 7.28%
- 15-year fixed-rate mortgage: 6.60%
These are national conventional mortgage benchmarks, not guaranteed investment-property quotes. Investor loans may carry different rates, down-payment requirements, fees, and underwriting standards. Still, the benchmarks demonstrate why financing must be included in a Clarksville rental analysis.
For example, using a hypothetical $192,000 loan:
- At 7.28% for 30 years, principal and interest would be approximately $1,310 per month
- At 6.60% for 15 years, principal and interest would be approximately $1,687 per month
The 15-year loan has a lower benchmark rate but a substantially higher required monthly payment. Depreciation may reduce taxable income under either structure, but it does not eliminate the higher debt-service obligation.
Before purchasing, compare cash flow under multiple financing scenarios. Haus’s guide on running the numbers on a Clarksville rental property discusses rent, taxes, insurance, vacancy, management, maintenance, capital reserves, debt service, cap rate, and cash-on-cash return.
What happens when you sell the rental property?
Depreciation reduces your adjusted tax basis over time. That can increase the taxable gain when you sell.
You may also face federal tax on depreciation that was claimed, or that was allowed to be claimed, even if you did not take the deduction correctly. This is commonly referred to as depreciation recapture or unrecaptured Section 1250 gain.
A former primary residence does not automatically avoid these rules after a PCS conversion. Your ownership period, personal-use period, rental-use period, selling price, improvements, and depreciation history may all matter.
Keep complete records for:
- Purchase documents
- Closing costs
- Improvement invoices
- Appraisals or valuation support
- Land-and-building allocation
- Placed-in-service date
- Annual depreciation schedules
- Prior tax returns
- Mortgage interest statements
Your CPA or tax adviser can help coordinate depreciation, passive-loss limitations, basis adjustments, and sale planning.
Which improvements should Clarksville investors track?
A repair generally keeps the property in its existing condition and may be deductible as a current rental expense when properly classified. An improvement generally adds value, restores the property, or adapts it to a new use and is typically capitalized and depreciated.
Examples that may require capitalization include:
- A new roof
- Major HVAC replacement
- Kitchen modernization
- A room addition
- New flooring throughout the property
- A driveway, fence, or other qualifying site improvement
- Built-in appliances
Do not rely on a general rule for every invoice. The correct treatment can depend on the scope, cost, timing, and applicable tax provisions.
How should you use depreciation when evaluating a Clarksville rental?
Use depreciation as part of an after-tax investment analysis, not as the primary reason to buy.
A complete review should include:
- Market-supported rent based on comparable leased properties
- Vacancy and collection-loss assumptions
- Property taxes and insurance
- Management and leasing costs
- Repairs and capital-expenditure reserves
- Mortgage payment and interest expense
- Depreciation and potential tax effects
- Long-term appreciation assumptions
- Exit costs and possible depreciation recapture
- Fort Campbell demand, neighborhood competition, and tenant turnover
Montgomery County properties near Fort Campbell may benefit from consistent military-related demand, but demand does not remove pricing, maintenance, vacancy, or turnover risk. Review local conditions by property and neighborhood. Haus also provides investor-focused information on Clarksville rental investing, cash flow, and the Fort Campbell factor.
What should you do before claiming depreciation?
Before filing a return, gather your closing statement, improvement records, conversion-date valuation, land-and-building allocation, and prior depreciation schedules. Then ask your tax professional to confirm:
- The correct depreciable basis
- Whether the property uses GDS or ADS
- The placed-in-service date
- The correct recovery period
- Whether improvements require separate treatment
- Whether passive-loss rules limit your deduction
- How depreciation may affect a future sale
If you are evaluating a purchase, conversion, or current rental, request a Clarksville rental-property analysis from Haus. A property-specific review can help you compare realistic rent, financing costs, operating expenses, projected cash flow, and investment returns before you commit.
