Cash Flow Isn’t Everything When You Buy Rental Property

Many investors fixate on the monthly cash-flow figure when evaluating rental properties, yet that single number rarely tells the complete story. A property showing solid pre-tax cash flow can still underperform once taxes, reserves, and financing realities enter the picture.

Cash Flow Is One Lens, Not the Whole Picture

Cash flow matters for liquidity, but it must be weighed against taxes, debt structure, reserves, maintenance, vacancy, insurance, and appreciation assumptions. A modest pre-tax number can look very different after legitimate non-cash deductions such as depreciation.

The Depreciation Case Study

IRS Framework

IRS Publication 527 and Publication 946 establish the rules. Land cannot be depreciated; only the building portion of the purchase price qualifies. Residential rentals generally use straight-line depreciation over 27.5 years under MACRS GDS with the mid-month convention.

Illustrative Monthly View

Consider a $300,000 purchase with land valued at 20 percent. The $240,000 building basis produces roughly $727 of monthly depreciation. When subtracted from $750 of pre-tax cash flow, taxable income drops dramatically, illustrating how the deduction can improve after-tax results even when pre-tax cash flow stays unchanged.

Depreciation is a non-cash deduction that does not reduce the rent check or mortgage payment but can meaningfully lower taxable rental income.
