A rental property quietly loses value on paper every year, and the IRS lets you deduct that loss even while the actual house in Franklin is holding or gaining market value. That gap between the paper loss and the real-world value is the whole point of depreciation, and it's one of the biggest reasons rental real estate pencils out the way it does.
Most first-time investors run their numbers on rent minus mortgage minus taxes minus insurance, land on a modest cash figure, and never add depreciation to the math. That's the deduction doing the heavy lifting in the background, and it's the one people most often leave on the table in year one.
The idea is that a building wears out over time. Residential rental buildings are depreciated over 27.5 years, which is the standard schedule the tax code uses for homes you rent out.
You take the value of the building (not the land under it) and divide it across those 27.5 years. Each of those years, you get to deduct roughly that slice against your rental income, which lowers the income you actually pay tax on.
Land doesn't depreciate, because dirt doesn't wear out. So a $400,000 purchase isn't $400,000 of depreciable basis. You separate out what the lot is worth and depreciate only the structure on top of it.
Say you buy a three-bedroom rental in a neighborhood off Hillsboro Road for $500,000. Your county appraisal and your closing documents help you split that between land and building, and let's say the building portion works out to $400,000.
Divide $400,000 by 27.5 and you get about $14,545 a year in depreciation. That's a deduction you claim every year without spending another dollar, on top of your real expenses like the roof repair or the property management fee.
If that rental throws off, say, $9,000 in taxable income after your other deductions, the depreciation can wipe that out entirely and then some. You collected the rent, but on paper the property shows a loss, and that paper loss can offset other income depending on how you file.
Here's where new investors cost themselves money: they either forget to separate land from building, or they assign too much value to the land and shrink their deduction for no reason.
The split matters because only the building depreciates. If you let a lazy estimate push more value onto the land, you're handing back deduction you were entitled to, year after year, for nearly three decades.
A common approach is to use the ratio from your property tax assessment, where the county already breaks out land value and improvement value. It's not the only method, but it's a defensible starting point your accountant can work from.
There's a catch worth knowing before you fall in love with the deduction. When you sell, the IRS wants to settle up on the depreciation you claimed, and that's called recapture.
The depreciation you took gets taxed when you sell, generally at a rate separate from your capital gains. So it's less a free lunch and more a timing advantage, deductions now, a bill later, with your money working for you in between.
Plenty of investors manage recapture through strategies like a 1031 exchange when they roll into the next property, which can defer it. That's a conversation for your tax professional, but knowing recapture exists keeps the surprise out of your eventual sale.
Depreciation shouldn't be an afterthought you discover at tax time. It should sit in your spreadsheet before you ever write an offer on a Franklin rental, because it changes whether a deal that looks thin actually works.
Two properties with identical rent can have very different after-tax returns depending on their purchase price, their land-to-building split, and your tax situation. The one with more building value relative to land gives you a bigger annual deduction, which is the kind of detail that separates a decent buy from a good one.
This is exactly where we spend time with investor clients at Redbird Real Estate, running the real after-tax picture on a property rather than just the headline cap rate. We're not your accountant, and we'll always tell you to loop one in, but we can make sure depreciation is in the conversation while you're still choosing, not after you've closed.
Keep your closing statement, because it's the document that anchors your basis and your land split. If you made improvements, like a new HVAC system or a kitchen renovation, those can be depreciated too, sometimes on their own schedules, so hang onto those invoices.
Talk to a tax professional who handles rental property specifically, not just a general preparer. The difference between someone who knows real estate and someone who doesn't can be thousands of dollars in deductions you're actually owed.
And if you're buying your first Franklin rental this fall and already weighing the numbers, build depreciation into them now. It's the quietest line on the spreadsheet and often the one that makes the whole investment make sense.
