Short-Term Rental Cap Rates in 2026: What Investors Need to Know Before They Buy

Gulf Shores, Alabama produced an average STR cap rate of 8.1% in the first half of 2026, according to StaySTRA data. Breckenridge, Colorado (where investors are also standing in line to buy) produced 4.6%. Both numbers are correct. Both markets have buyers writing offers today. The reason anyone can hold those two numbers in the same brain without contradiction is that they understand what a short-term rental cap rate actually measures, and why market type changes everything before you run the math.

Cap rate is the most-cited metric in STR investment conversations, and also one of the most misapplied. The formula looks simple. The inputs are not. Most online sources still treat STR cap rate the same way they treat long-term rental cap rate: same vacancy assumption, same expense ratio, same interpretation of what a “good” number looks like. That produces comparisons that mislead investors in both directions. Properties that look attractive are sometimes marginal, and properties that look marginal are sometimes the stronger deal.

This article walks through how STR cap rate actually works, how it differs from the LTR version most investors learned first, what StaySTRA data shows across market types in 2026, and how it connects to the other metrics that together build a real investment picture.

What STR Cap Rate Is and How to Calculate It

The cap rate formula is the same regardless of rental type:

Cap Rate = Net Operating Income (NOI) / Property Purchase Price

Net Operating Income is gross revenue minus operating expenses. Think of it like the operating profit a business produces before financing costs. Cap rate is designed to evaluate the property as a standalone income-producing asset, independent of how you choose to finance it. Before debt service, before your down payment, before your personal tax situation enters the equation.

For a short-term rental, that works out to:

STR Cap Rate = (Gross Annual STR Revenue minus Annual Operating Expenses) / Purchase Price

Here is a worked example using StaySTRA’s 2026 data for Destin, Florida.

StaySTRA shows an average daily rate of $395 and an average occupancy rate of 62.8% for Destin in the first half of 2026. At that occupancy level and ADR, a representative property generates roughly $76,560 in gross annual revenue. Operating expenses for a professionally managed STR in a beach market typically run 38-42% of gross revenue. At 40%, that is $30,624 in expenses, leaving a net operating income of $45,936. The median home price in Destin in 2026 is approximately $645,000.

Cap rate: $45,936 divided by $645,000 equals 7.1%.

That is the number. Now here is what makes it interpretable: it does not include any mortgage payment. It tells you that this property, bought for cash, would produce a 7.1% annual return. Whether it makes sense for your deal depends on what you paid, how you financed it, and what 7.1% means given your financing costs. That is where cash-on-cash return enters the picture, and we will get there shortly.

How STR Cap Rate Differs From Long-Term Rental Cap Rate

The formula is identical. The inputs are where STR and LTR diverge, and where most first-time investors make their first calculation mistake.

Vacancy: Dynamic, Not Fixed

Long-term rental underwriting treats vacancy as a fixed assumption, typically 5-10% annually. An investor modeling a long-term rental in Nashville might plug in 8% vacancy, meaning the property sits empty for roughly one month per year under normal conditions.

STR vacancy does not work that way. Occupancy is a function of ADR, listing quality, platform visibility, local event calendar, seasonality, and market competition level. A 55% annual occupancy rate in Gatlinburg is not the same risk as a 55% occupancy rate in Nashville. One is driven by tourism seasonality; the other often reflects a market supply dynamic that a new listing walks into regardless of how well it is managed. StaySTRA data helps you understand which situation you are walking into before you close, not after.

Operating Expenses: Meaningfully Higher Than LTR

This is the input that catches investors off guard most often. Long-term rental operating expenses typically run 25-35% of gross revenue, covering property management (8-12%), repairs, insurance, and property taxes.

STR operating expenses run 35-50% of gross revenue. The difference comes from costs that simply do not exist in long-term rentals: cleaning and turnover between every stay (often $100-250 per cleaning depending on property size), consumables like toiletries and paper goods, platform fees, STR-specific insurance, and the higher management fees that professional STR property managers charge (typically 20-30% of gross revenue versus 8-12% for long-term rental management).

Do not let the higher expense ratio discourage you before you look at the revenue side. The point is to use accurate numbers in your model, not to treat higher expenses as a dealbreaker. Think of it this way: a long-term rental is something like a vending machine you service monthly, while an STR is more like a hotel room that needs to be reset and restocked before every guest. The revenue potential is higher. The operating model is genuinely more intensive. Both statements are true at the same time.

Platform Dependency and Regulatory Exposure

A long-term rental’s income depends on one tenant and one lease. An STR’s income depends on platform algorithms, listing reviews, policy changes, and local regulations that can shift in a single city council meeting. Cap rate does not capture any of those variables on its own. The income may be real today; the question is how durable it is, and that is a separate analysis you have to do alongside the cap rate calculation.

STR Cap Rates by Market Type in 2026

StaySTRA’s 2026 first-half data across our market database shows meaningful variation by market category. The figures below combine actual ADR, occupancy, and revenue data from StaySTRA with 2026 median home prices from Zillow and Redfin.

Beach and Coastal Markets: Strongest Cap Rates in the Database

Beach markets are producing the best STR cap rates in StaySTRA’s 2026 data, with the most accessible price points delivering the strongest returns. Gulf Shores, Alabama is the standout figure this year: average ADR of $384, occupancy of 62.9%, and gross annual revenue of approximately $69,780 against a median home price near $517,500. That combination produces cap rates in the 6.7-8.8% range depending on whether your expense ratio lands closer to 35% or 50%.

Destin, Florida shows similar ADR ($395) and nearly identical occupancy (62.8%), but the higher median home price (approximately $645,000 in 2026) compresses cap rates to the 5.9-7.7% range. Both are legitimate beach markets with deep demand histories. The difference is purely in the denominator: Destin’s pricing reflects the premium its brand commands, and Gulf Shores investors benefit from being in a physically adjacent market with lower entry costs.

The pattern in coastal markets generally: properties below $600,000 in high-occupancy beach destinations tend to produce the most reliable STR cap rates. As prices climb into the $700,000-plus range, cap rates compress even when ADR and occupancy hold steady, because the purchase price grows faster than the income it supports.

Mountain and Cabin Markets: Two Very Different Stories

Mountain markets break into two distinct categories, and treating them as a single group produces bad analysis.

Smoky Mountain and Appalachian cabin markets: Gatlinburg, Tennessee shows average ADR of $382, annual occupancy around 51.2%, and gross annual revenue of approximately $51,612. Against a median home price near $650,000, cap rates land in the 4.0-5.2% range. Occupancy is the limiting factor, not ADR. The market has enough supply that properties do not fill every week, and purchase prices have risen to reflect STR demand even as occupancy has plateaued in recent years.

Premium ski markets: Breckenridge, Colorado tells a dramatically different story. Average ADR of $777, average monthly revenue around $8,328. But median home prices near $1,300,000. Even with revenue that is nearly double Gatlinburg’s, the cap rates land in the same range: 3.8-5.0%. Park City, Utah is comparable or lower depending on the neighborhood.

Stay with me here, because this is one of the most important distinctions in STR investing: a lower cap rate does not automatically mean a worse investment. It means a different investment thesis. Premium ski market buyers are often targeting long-term appreciation alongside STR income. They are not pure cash flow investors. Both approaches can make sense depending on what you are building, but the approach needs to be intentional, not accidental.

Urban Markets: Most Variable by City

Urban STR markets show the widest spread in StaySTRA’s data because regulatory environment, permit availability, and housing prices vary so dramatically from city to city.

Nashville, Tennessee shows a 58.5% occupancy rate, ADR of $368, and gross annual revenue around $57,372. Against a median home price near $510,000, Nashville STR cap rates run approximately 5.6-7.3%, making it one of the stronger urban market performers in StaySTRA’s database for 2026. Scottsdale, Arizona shows 66.2% occupancy (the highest of any market in this analysis), ADR of $359, and gross annual revenue around $54,996. At a median home price near $625,000, cap rates run approximately 4.4-5.7%.

Denver, Colorado shows a different picture: ADR of $208, 67.9% occupancy, and monthly revenue around $3,034, or approximately $36,408 annually. At Denver’s median home price near $575,000, cap rates compress to the 3-4% range, barely above typical long-term rental returns in the same city and well below what DSCR financing requires at current rates.

Cap Rate vs Cash-on-Cash Return: When to Use Which

Cap rate and cash-on-cash return are two of the three metrics every STR investor needs to understand before making an offer. They look similar but answer different questions, and knowing when each one is the right tool is what separates an experienced investor from someone who got lucky on their first deal.

Use cap rate to evaluate the property as an asset, independent of financing. Cap rate lets you compare properties across markets, benchmark a listing against what the market is producing, and see whether a seller’s claimed income holds up against the price being asked.

Use cash-on-cash return to evaluate what your actual invested capital is earning after the mortgage. It takes NOI, subtracts annual debt service, and divides by your actual cash invested: down payment plus closing costs.

Back to the Destin example: 7.1% cap rate, $645,000 purchase, 25% down ($161,250). A 30-year DSCR loan at 7.5% produces a monthly payment of roughly $3,384, or $40,608 annually. Cash-on-cash return: ($45,936 NOI minus $40,608 debt service) divided by $161,250 equals approximately 3.3%.

Both numbers are accurate. They tell you different things. At current DSCR rates, leverage does not dramatically amplify STR returns the way it did in the 2020-2021 low-rate environment. The cap rate needs to sit meaningfully above your mortgage rate before debt amplifies your cash return rather than compressing it.

What the StaySTRA Analyzer Can Help You Validate

A cap rate calculation is only as reliable as the revenue figure you put into it. The most common mistake first-time STR investors make is using gross revenue from a listing description or from an Airbnb calendar screenshot. That number may reflect one exceptional year, a period of lower local supply, or a property that has since been refurnished and relisted at a different tier.

The StaySTRA analyzer gives you current market-level ADR and occupancy data built from actual booking patterns rather than projected estimates. When you are underwriting a deal and building your cap rate model, the analyzer is where you anchor the revenue side of the calculation. It is the difference between calculating cap rate on what the market is actually producing in 2026, and calculating it on what a motivated seller’s best year looked like.

The Cap Rate Floor for DSCR Financing

DSCR lenders do not underwrite STR income the same way they underwrite long-term rental income, and the difference matters significantly when you are sizing your down payment and evaluating whether a property will qualify for standard financing terms.

Most DSCR lenders apply a mandatory 20% expense reduction to gross STR revenue before calculating the coverage ratio. If your property generates $76,560 in gross annual revenue, the lender calculates coverage on $61,248. The property then needs to cover annual debt service (principal and interest) at a ratio the lender requires, typically 1.0x at minimum for approval and 1.25x for better pricing.

At current DSCR rates of 7.0-7.5% for STR properties, a property generally needs a cap rate in the range of 6-8% to qualify for standard DSCR financing at 75% LTV. Properties with cap rates below that threshold (including many premium ski market properties in the 4-5% range) may require a larger down payment, carry a rate premium, or may not qualify for standard DSCR underwriting at all. They are not automatically bad investments. They are just not DSCR-friendly at standard terms, which affects your financing options going in and should factor into how you think about entry price.

Red Flags: When a High Cap Rate Is a Warning Sign

I have spent a long time in Santa Fe watching investors drive past properties that looked great on paper and regret it later. A cap rate above 10% on a listed STR should not make you excited before you have answered a few questions.

The most common cause of an artificially inflated cap rate is a purchase price that does not reflect actual market value. The property has deferred maintenance, regulatory exposure, or physical problems that the income figures do not capture. A cabin priced at $350,000 showing $45,000 in gross annual revenue looks like a compelling number until you discover the HOA has voted to restrict STRs, or the septic system needs $40,000 in repairs, or the revenue figure is a projection rather than documented history.

Other situations that produce misleadingly high cap rates include:

• Exceptional-year revenue: A property that benefited from a nearby major event (a championship game, a concert series, or a festivalval. Those properties will show elevated trailing revenue that does not represent a normal operating year. Always check whether the revenue period was representative of typical local conditions.
• Missing the expense deduction: Some listings present “gross cap rate,” which is simply revenue divided by price with no expense deduction. That is gross yield, not cap rate, and it is typically double what the actual cap rate would be after real operating costs are accounted for.
• Regulatory vulnerability already priced in: Markets where STR permitting is under regulatory threat often show elevated cap rates because asset prices have already discounted some of the risk. The income is real today; the question is whether local policy changes it in year two or three.
• Thin market data: A market with very few comparable properties and limited booking history produces less reliable occupancy projections. Higher uncertainty can show up as inflated revenue projections in a listing.

The StaySTRA analyzer gives you a ground-truth revenue check before you rely on a seller’s numbers. Run the market data before you run the cap rate math. That sequence is the most basic form of STR investment due diligence.

We do our best to keep our data accurate and up to date, but markets move fast and we are only human. Always verify current figures directly with local sources before making investment decisions.

The revenue estimate you build your cap rate on determines whether the number means anything. Run your target market through the StaySTRA analyzer to get the ADR and occupancy figures investors in that market are actually seeing in 2026, not a projection from a listing description or a number from two years ago when market conditions were different.
