To value a short-term rental property, start with the income it can realistically produce: project a year of bookings, subtract every operating cost to reach net operating income (NOI), and divide that NOI by a cap rate drawn from recent sales of comparable rentals. Sold comps and replacement cost then tell you whether the number holds up, and the depreciation you can claim decides what the property is worth to you after tax.
As co-founder of Seneca Cost Segregation and a real estate investor myself, I see STR purchases from both the buyer’s side of the table and the engineer’s side of the report. We see a familiar pattern when coordinating with CPAs after closing: the buyer ran careful revenue numbers, then signed a contract that rolled the land, the house, and the furnishings into one price that has to be pulled apart before any depreciation can be claimed.
Below, I walk through the five-step valuation, a worked example on a furnished cabin, and the tax layer most valuation guides skip, including how the price splits for depreciation and what that does to your first-year return.
TL;DR — How to Value a Short-Term Rental Property
- ●Value starts with NOI: project a year of bookings, subtract every operating cost, and divide by a cap rate taken from local STR sales.
- ●A one-point cap rate swing moves value by about $100,000: in our example, $36,200 of NOI is worth $658,182 at 5.5% and $556,923 at 6.5%.
- ●Offer on market value and judge the deal on investment value: your financing, hours, and tax bracket decide whether the deal works for you, and they belong outside the price you offer.
- ●Split the price before you close: land is never depreciable, and the IRS lets you use the assessor’s land ratio when fair market values are uncertain.
- ●A study can more than triple year-one depreciation: our hypothetical cabin goes from $37,331 to $131,380 with 100% bonus on furnishings and reclassified components.
- ●Plan for recapture at exit: furnishings and other personal property recapture as ordinary income, and building gain is taxed at up to 25%.
Know Which Value You Are Estimating
Two different numbers can answer the question of what an STR is worth, and buyers who blur them tend to overpay.
Market Value Versus Investment Value
IRS Publication 561 defines fair market value as the price a willing buyer and a willing seller would agree on, with neither forced to act and both reasonably informed. That is the number an appraiser, a lender, and the next buyer will look for.
Investment value is narrower, measuring what the property is worth to you specifically, given your financing, the hours you will put in, and your tax bracket, so two buyers can study the same cabin and reach different investment values while its market value stays put.
The working rule is to build your offer from market value and use investment value to decide whether the deal clears your bar.
Treat the Listing Price as a Starting Point
Listing prices for STRs are often set from the seller’s best year, a pro forma, or the sale price of a similar house nearby. None of those tell you what the property will net under your ownership.
Ask for the platform payout reports, the booking calendar, and the expense records for at least the last 12 months. Peak-season screenshots show the best case, and payout history shows the whole year.
Value a Short-Term Rental in Five Steps
The income approach anchors the number, and comps, cost, and cash-on-cash tell you whether to trust it.
Build a Realistic Revenue Estimate
Rental revenue comes from two inputs: the average daily rate (ADR) and the number of nights booked. Multiply them, then add the cleaning fees guests pay, since those fees land in revenue and the cleaning bill lands in expenses.
Build the estimate month by month from the seller’s trailing 12 to 24 months of payouts, and cross-check it against market data tools that track nearby listings. Seasonality matters more than the annual average, because a lake house that books solid in July can sit empty in February.
If the seller ran the property part-time or blocked weeks for personal use, adjust for the calendar you plan to run instead of copying their totals.
Subtract Every Operating Expense
Net operating income is what remains after a full year of running costs. STR expense lists run longer than a long-term rental’s, since you are operating a small hospitality business.
Include each of these, even when the seller’s numbers leave some out:
- ●Cleaning and laundry for every turnover
- ●Management or co-host fees, if you will not run the rental yourself
- ●Utilities, internet, and streaming services
- ●Consumables such as toiletries, coffee, and paper goods
- ●Short-term rental insurance and property tax
- ●Repairs, maintenance, and pricing or booking software
- ●Platform and payment processing fees
- ●A reserve for replacing furniture, mattresses, linens, and appliances
Apply a Market Cap Rate to NOI
The capitalization rate converts one year of NOI into a value, and Publication 561 lists capitalization of income among the standard methods for valuing real estate. The formula is NOI divided by the cap rate.
Derive the rate from recent sales of comparable STRs in the same market by dividing each sale’s NOI by its sale price. House comp sheets often leave NOI out, so you may need to request operating figures through the agents involved.
Small changes in the rate move the answer a lot. On $36,200 of NOI, the gap between a 5.5% and a 6.5% cap rate is more than $100,000 of value.
Check the Result Against Sold Comps
The comparable sales method measures the property against similar ones that have sold. For an STR, that comparison only holds when the comps could legally operate as rentals and changed hands in similar condition.
Adjust for the differences that move rental income:
- ●Permit or license status, and whether it transfers to a buyer
- ●Whether the sale included furnishings, linens, and kitchen equipment
- ●Amenities guests pay more for, such as a hot tub, game room, or view
- ●Bedroom count and sleeping capacity, which cap the nightly rate
- ●Review history, which may help bookings but may not move to a new owner’s account
When the income value and the comps disagree by a wide margin, find out why before you write an offer. A large gap usually means the revenue estimate is off or the comps are not true STR comparables.
Cross-Check With Cost, GRM, and Cash-on-Cash
Three quicker checks catch errors in the main number:
- ●Cost approach: estimate the land plus the cost to rebuild, less wear. Publication 561 notes that this method used alone usually does not establish fair market value and tends to set the upper limit, so a price well above replacement cost deserves a second look.
- ●Gross rent multiplier: divide the price by gross annual revenue. The GRM ignores expenses entirely, so use it to sort listings and use NOI to value them.
- ●Cash-on-cash return: divide annual pre-tax cash flow after debt service by the cash you put in, including the down payment, closing costs, furnishings, and startup costs. Cash-on-cash is where financing enters your investment value.
Buyers planning a long hold sometimes add a discounted cash flow model, projecting several years of NOI plus a sale price and discounting them back to today. A DCF earns its keep when you expect income to change, such as after a renovation or a new permit.
Work Through a Short-Term Rental Valuation Example
Assume a furnished three-bedroom cabin is listed at $725,000. The seller’s records show 170 booked nights at an average rate of $430 across 48 stays, and the buyer plans to use a co-host.
Suppose comparable STR sales in this market traded at cap rates between 5.5% and 6.5%. Applying that range to the cabin’s NOI gives these values.
At the asking price, the cabin would trade at a cap rate just under 5.0% and a GRM of 8.9. If sold comps do not support a rate that low, the income math points to an offer between roughly $600,000 and $660,000, and in this example the buyer closes at $640,000.
Separate Land, Building, and Furnishings in the Price
The price you agree on is also the starting point for depreciation, and the IRS expects it to be split before any of it is deducted.
IRS Publication 551 says that when you buy several assets for one lump sum, you allocate the price among them in proportion to their fair market values. Settlement fees and closing costs such as title insurance and legal fees add to basis, while amounts escrowed for future taxes and insurance do not.
Land comes out first, since IRS Publication 527 does not allow land to be depreciated. When fair market values are uncertain, the IRS lets you divide land and building using the assessed values on the property tax bill, and our guide on how to determine land value compares that ratio with an appraisal.
Furnishings are the second piece. A turnkey STR often sells with furniture, linens, kitchenware, and decor, and those items are personal property with a far shorter recovery period than the house.
Working with STR buyers on post-closing studies, what we see consistently is a contract that names one figure for everything, which leaves the CPA estimating the furnishings value after the fact. A separate bill of sale at a supportable value gives you a documented number from day one, and our article on tangible personal property identification explains which items belong in that category.
Add Depreciation to the After-Tax Return
Depreciation sits outside NOI and market value, yet it can move your first-year cash flow more than any expense line.
Match Each Part of the Property to Its Recovery Period
Each part of the price depreciates on its own schedule:
- ●Furniture, appliances, and carpeting: 5-year property when used in a residential rental real estate activity, according to Publication 527.
- ●Land improvements: fencing, landscaping, and paved walkways fall in the 15-year class under IRS Publication 946.
- ●The building: 27.5 years if it qualifies as residential rental property, or 39 years as nonresidential real property.
The building class is the judgment call for STRs. Under 26 U.S.C. 168(e)(2), a dwelling unit excludes a unit in a hotel, motel, or other establishment where more than half the units are used on a transient basis, so your CPA decides whether a short-stay rental runs on the 27.5- or 39-year schedule.
Model Year One With and Without a Cost Segregation Study
A cost segregation study breaks the building into its components and moves the shorter-lived ones out of the building line. For property acquired and placed in service after January 19, 2025, those 5-, 7-, and 15-year components qualify for 100% bonus depreciation, and our breakdown of bonus depreciation under the Big Beautiful Bill covers the lower rates for earlier contracts.
Assume the cabin goes into service in March 2026 and a study moves $96,000 of the building into shorter classes. The table uses the 39-year schedule, and a 27.5-year classification would raise the building line a little.
The last row only applies if you can use the loss against other income. Under IRS Publication 925, a property with an average guest stay of 7 days or less is not treated as a rental activity, so the loss can be nonpassive when you materially participate, and our page on whether cost segregation can offset W-2 income explains the tests.
Every preliminary estimate we provide at Seneca is built by our engineering team from the purchase price, the land allocation, and the property details you send, so this comparison can run on real figures before you file. Our guide to a cost segregation study for a short-term rental covers what our engineers look for on furnished properties.
Price Depreciation Recapture Into the Exit
Depreciation lowers your basis, so part of it returns as taxable gain when you sell. Depreciation on personal property such as furnishings and appliances is generally recaptured as ordinary income under Section 1245, up to the amount of the gain.
The building portion follows a different rule, with unrecaptured Section 1250 gain taxed at a maximum 25% rate under IRS Topic 409. Our page on the depreciation recapture tax rate walks through the math, and a DCF that skips these taxes will overstate what the hold is worth to you.
Adjust the Value for Permits, Rules, and Amenities
Two STRs with identical revenue can still deserve different prices once legal and physical risk is priced in.
Start with legality. Confirm the property may operate as a short-term rental under the local ordinance, whether a permit or license is required and transfers on sale, and whether HOA covenants restrict rentals; a property that cannot legally rent short-term should be valued as a house. Pending ordinances deserve the same scrutiny, since a cap on permits or a minimum-stay rule can cut the revenue the value rests on.
Amenities cut both ways. A hot tub, game room, or fire pit can lift the nightly rate, and the equipment and site work behind them can include short-life property a study identifies, but each one also adds upkeep and replacement cost that belongs in your expense line.
Avoid These STR Valuation Mistakes
Each of these leads buyers to pay too much or to lose part of the tax benefit they counted on.
- ●Valuing off the best months: annualizing a strong summer overstates revenue and value. Build the estimate month by month from payout history.
- ●Skipping the furniture reserve: furniture, mattresses, and appliances turn over with guest use, and leaving replacement out of expenses inflates NOI. Budget a yearly reserve before applying the cap rate.
- ●Paying for your own tax benefits: bonus depreciation depends on your participation and bracket, so building it into the offer transfers its value to the seller. Offer on market value and keep the tax upside as your margin.
- ●Ignoring permit status: a comp or subject property that cannot legally rent short-term breaks the income approach. Verify the permit and its transferability before you rely on any revenue figure.
- ●Lumping furnishings into the house price: one undivided price leaves the furnishings value to be reconstructed later. Document furnishings on a bill of sale at closing.
- ●Leaving recapture out of the exit math: the sale price overstates what you keep after tax. Model Section 1245 and Section 1250 recapture into the final year of any hold-period analysis.
