CapEx

Capital expenditure

Capital expenditure is money spent on components with a useful life longer than a year — roof, furnace, windows, a full kitchen. It is not deducted in the year you spend it; it is added to basis and depreciated. In underwriting, a CapEx reserve of 5% to 10% of gross rent is set aside monthly so the eventual bill is already funded.

CapEx reserve = gross scheduled rent × reserve percentage

Worked example

5% of $31,800 of scheduled rent puts $1,590 a year, $133 a month, into the reserve.

Every example in this glossary uses the same deal: a $265,000 duplex renting for $2,650 a month, bought with 25% down at 6.75% over 30 years, producing $19,310 of net operating income.

The mistake to avoid

Confusing a repair with an improvement. Patching a roof is a repair and deductible now; replacing it is capital and depreciates over 27.5 years. Getting this wrong misstates both cash flow and the tax return.

Where this is calculated

The rental property depreciation calculator computes this from your own numbers and shows the arithmetic expanded. 27.5-year straight line with the IRS mid-month convention, the annual tax shield, and recapture at sale.
