What to Consider When Buying a Short-Term Rental in Summit County, Colorado

I'm going to start with the thing you don't want to hear.

At today's prices and interest rates, without putting more than 50% down, almost NO property in Summit County cash flows. Not the condo in Breckenridge. Not the one in Keystone. Not the single family home you liked in Silverthorne. That isn't a knock on any particular listing. That's the entire market right now.

You're probably wondering why a realtor would lead with that. Here's why: you're going to run these numbers yourself eventually, and I'd rather you hear it from me first.

Once you accept it, the goal changes. You're not hunting for a property that pays you. You're looking for a property you love, where the short-term rental income makes it comfortable for you to own.

That's a very different search. Summit County is full of properties perfect for building memories in the mountains where short term rentals cane make them more comfortable to own for years to come. 

I've been a realtor since 2013, I serve Summit, Park, and Chaffee counties, AND I owned an Airbnb myself — so I've run these numbers as an owner, not just as an agent.

Here's how to pick a property that rents as well as it possibly can to support your dream of owning in the mountains. 

Start With the License, Not the Listing

The most expensive, and disappointing, mistake I watch buyers make is falling in love first and checking the rules second.

Here's the line that matters most: short-term rental licenses in Summit County do NOT transfer at closing. The seller's active license is worth nothing to you. What matters is whether a new license is available for that address on the day you close.

Buying a short-term rental without checking the zone first is like buying the restaurant and finding out the liquor license doesn't come with it.

Where the property sits decides everything — first town limits versus unincorporated county, then which zone or basin it falls in. A quick lay of the land:

• Breckenridge Zone 1, the tourism zone west of Main Street, has licenses available with no waitlist. Zone 3, the outlying residential neighborhoods, is capped at 10% of properties with an estimated wait of more than 20 years. Zone 3 is not a viable path if rental income is part of your plan.
• The unincorporated county Resort Overlay Zone has no cap. That covers Keystone Resort, Copper Mountain, and two neighborhoods that look like Breckenridge on a map but aren't: 4 O'Clock and SkiWatch. The Neighborhood Overlay Zone is capped by basin, all four basins sit at or above cap, and Type II licenses there are limited to 35 bookings a year.
• Frisco is capped with an active waitlist. Dillon and the Town of Keystone have no cap. Blue River froze new licenses through December 31, 2026.

I wrote a complete guide to all of it. Short-Term Rental Rules in Summit County: The Complete Guide. Read that before you tour anything.

Then Read the HOA

The town can say yes and the HOA can still say no.

Your building's rules can't give you anything the town won't allow, but they can take plenty away. Before you're under contract, find out whether short-term rentals are permitted at all, whether there's a minimum night stay, whether the building caps how many units can rent, whether you have to register, and whether you're required to use an on-site rental program. Pet and parking rules matter too, because both affect what you can charge.

The HOA also quietly sets your margin. Dues, reserve fund health, and special assessment history come straight off your bottom line. HOA Gotchas in Summit County. Grab the HOA checklist while you're there.

What Actually Books

Location first, and it isn't close. Walk-to-lift or walk-to-Main-Street beats everything else, then a free shuttle route, then drive-and-park. Ski-in/ski-out carries a real premium, and the honest question is whether the nightly rate justifies the price per square foot. Sometimes you're paying for a feature that photographs better than it books.

Summer and shoulder season matter more than buyers expect. Breckenridge occupancy swings from roughly 89% in February to 23% in May. Trailhead access, Lake Dillon, the rec path, and dog-friendliness are what fill the soft months.

Parking is a booking feature, not a detail. Breckenridge requires one space per bedroom plus one, with a $300 per space fee if you can't meet it. Guests driving up from Denver with a rooftop box filter for parking before anything else.

Then the unit itself. Sleeping capacity drives your nightly rate more than square footage does. Most Summit County jurisdictions and the Resort zone cap occupancy at two guests per bedroom plus two, which puts a ceiling on what you can charge no matter how big the place is. Bathroom-to-bedroom ratio matters too — a three-bedroom with one bathroom books like a two-bedroom.

Know the difference between true bedrooms, lofts, and bunk rooms. A lock-off lets you rent half the unit and use the other half yourself. One caveat: you can't get two licenses for a single unit, so a lock-off isn't a loophole for two separate listings. It's a way to rent part of your place and keep the rest.

Then the features that live inside search filters: hot tub, ski storage, garage, in-unit laundry, fast wifi, pet-friendly, ground floor or elevator. Guests filter — if you don't have the box, you don't appear. Furnishing is real money, so ask what conveys and get it in writing. One counterintuitive point: one-bedrooms often post the best return here, because the Breckenridge condo market is flooded with two- and three-bedrooms.

Rental History and Projections

This is where most buyers get it wrong, and they get it wrong in both directions.

Ask for documents, not the pitch

Request two to three years of owner statements — monthly gross and net, occupancy by month, average daily rate by month, cleaning fee revenue. Ask for the actual Airbnb or VRBO listing URL so you can read the reviews and look at the forward calendar.

Understand that many units won't have a breakdown that detailed. Plenty are self-managed, and the owner will literally only have a record of nights booked and nightly rates. Some will only have gross rent collected for the past year. Buying a unit without the full picture is simply a risk you're taking, and it's a fair thing to weigh in what you offer.

Gross revenue with no expense side isn't data. It's marketing.

Know what a projection actually is

AirDNA, Rabbu, and property management proformas are modeled from comparable listings, not from that specific unit. They're useful as a range and dangerous as a promise. My rule: take the projection, cut 10 to 15%, then run it again as though it were a low-snow winter. Low snow means fewer bookings, which means owners discount, which means your average daily rate assumption breaks.

For context, Breckenridge market-wide runs roughly $58,000 to $64,000 median annual revenue per listing, 54 to 62% occupancy, and an average daily rate in the $600s. A market median is not a promise for one unit.

The line item buyers always forget

Owner-use nights are revenue you're choosing not to earn, and the weeks you most want — Christmas, Presidents' Day, spring break — are the most valuable weeks on the calendar. Put a dollar figure on your own use before you decide what a property "makes."

This cuts both ways when you're reading someone else's history. Some units show low revenue because the owners used them heavily. On the flip side, if you plan to use the place for peak demand weeks, or for a full month in the winter, don't compare that plan against a rental history where the owners hardly used it at all.

Why history cuts both ways

Bad photos, bad pricing, or a lazy manager can suppress a genuinely good unit. That's opportunity. On the other hand, a Superhost's five years of reviews leave with the seller. You start at zero reviews on day one.

Run the Real Numbers

Build the whole expense stack

Principal and interest. Property taxes. Insurance, which runs higher on mountain properties with short-term rental coverage than you're probably used to. HOA dues. Utilities and internet. Property management at roughly 25 to 35%, or the cheaper path of hiring only a Responsible Agent and self-managing the rest. Cleaning, restocking, and supplies. Snow removal — though if you're buying a condo the HOA almost always covers it, so that's mainly a single-family home expense. Repairs and a furniture replacement reserve. Bookkeeping and your CPA.

Then the licensing costs, which vary more than people expect:

And lodging tax, where the spread is enormous. Keystone collects 8.375%, the lowest in the county. Dillon collects 19.875%, the highest. On $60,000 of revenue that's roughly $7,000 a year of difference for doing exactly the same thing.

Then ask the right question

Not "does this cash flow." We covered that. The right question is: how much of my monthly cost does the rental income cover?

Here's what that looks like on two properties I have listed right now.

Example 1: 465 Four O'Clock Road #223, Breckenridge — $1,175,000

Two bedrooms, three baths, 1,112 square feet, directly across from the 4 O'Clock ski run and a quarter mile to Main Street. Zone 1, licensed, furnished, with a garage space.

This one has four years of real owner statements. Rental revenue was $50,412 in 2022, $67,091 in 2023, $84,909 in 2024, and $75,341 in 2025 after a low-snow winter. That dip is worth naming, because it's exactly the low-snow scenario I just told you to model. On top of the 2025 rent, the owner collected $4,025 in cleaning fees, bringing total collections to $79,366.

With 20% down at today's second-home rates, the total cost of owning and operating this condo runs about $9,284 a month. Short-term rental income covers about 71% of that. Your actual out-of-pocket lands near $2,670 a month, against roughly $7,398 if you owned it and never rented it at all. Renting it cuts your cost of ownership by 64%.

Then add this. In year one, roughly $9,923 of your mortgage principal gets paid down. Your guests are buying you equity. Net of that, your real cost is closer to $1,843 a month.

One more thing worth knowing. The current owner pays a flat $250 a month for management, under 4% of revenue, rather than the 25 to 35% a full-service company charges. That's a hands-on owner's playbook and it's available to you. If you plan to hand everything off, budget differently.

Example 2: 21640 US Highway 6 #2121, Keystone — $650,000

One bedroom, one and a half baths, 898 square feet, gut renovated in fall 2025, golf course and mountain views, pet friendly, with a ski shuttle to the resort. Keystone has no license cap at all, which is worth pausing on — against Breckenridge Zone 3's twenty-year wait and Blue River's freeze, being able to simply get a license is a real asset.

This one has no rental history. It has a projection from SummitCove: $32,935 to $36,939 gross, with the high end assuming you allow dogs. Read it the way I told you to. "Owner Net Income" on a management proforma means gross revenue minus their commission and nothing else. Your HOA, taxes, insurance, utilities, and mortgage all sit outside that number. SummitCove also states plainly that year one runs below the range and the full estimate arrives by year three, which is an unusually honest disclosure and worth budgeting around.

With 20% down, total monthly cost runs about $5,400. The rental income covers 51 to 56% of it, putting your out-of-pocket at $2,407 to $2,657 a month, against roughly $4,659 if you never rented it. Principal paydown adds another $5,489 in year one, which brings your true cost to right around $2,200 a month.

The unit is unfurnished, so budget $25,000 to $35,000 to furnish it, and Keystone adds a 2% real estate transfer assessment at closing.

The Part I Find Most Interesting

Once you count the principal your guests pay down, the Breckenridge condo costs you about $1,843 a month. The Keystone condo costs you $1,950 to $2,200. The property that costs $525,000 more to buy is the cheaper one to hold.

That is not a typo, and it is not an argument that you should buy the more expensive one. It is the whole point of running the numbers this way. Purchase price tells you what you need at closing. It tells you almost nothing about what a property costs you to own once it is working. Which of these is right for you has far more to do with how you want to use it — walk to the lift in Breckenridge, or a quieter one-bedroom on the golf course with a shuttle to Keystone — than with the spread between the two price tags.

What changes the math

More money down. A lower-tax town. Self-managing with a Responsible Agent instead of a full-service company. A one-bedroom instead of a three-bedroom. Buying in shoulder season when you have less competition.

On financing: second homes require a minimum of about 10% down, investment properties run 20 to 25%, and DSCR and STR-specific loans exist. Financing Short-Term Rental Properties in Summit County.

On taxes: depreciation, the short-term rental material participation rules, and how your personal-use days affect deductibility all matter, and all of it belongs in a conversation with your CPA. I'm not one.

The Takeaway

The property that rents best might not be the one you personally want the most. Decide which one you're buying, and be honest with yourself about the answer.

Is this primarily a place for you, where rental income offsets the cost of owning it? Summit County is great for that. Or is the goal an investment property you'll use a few days a year? Be realistic about what your financial goals are and whether a property here actually meets them.

Both are legitimate. They're just not the same search, and they don't lead you to the same property.
