STR Revenue Reality:
What the Numbers Actually Show

By Brian Elmore  ·  Updated April 2026

← Back to Resources

Every short-term rental listing on Airbnb or VRBO has an "estimated annual revenue" figure somewhere nearby. It is almost always wrong, and almost always optimistic. It's a marketing number, not a financial projection. Before you build a purchase decision around what a lakeshore STR could earn, you need a different kind of math: one that starts with realistic gross revenue and then works honestly through every dollar that comes out the other side. That's what this article is about.

The gap between gross revenue and what you actually keep

Gross revenue is the total that guests pay to stay at your property. It's the number that shows up in platform projections, in property management pitches, and in the listing descriptions of properties being sold as turnkey STRs. It is not the number that matters for your financial model.

By the time you subtract platform fees, management fees, cleaning costs, consumables, maintenance, property taxes, insurance, and utilities, the cash that remains can be a fraction of that headline figure. On a well-performing lakeshore property, an owner who has done everything right might net 35 to 50 cents on every gross revenue dollar. On a property with high management costs, an aggressive mortgage, or below-average occupancy, the net can be much lower than that. Some properties that look profitable on a gross revenue basis don't cash flow at all once the full expense picture is applied.

The question worth asking isn't "what will this property gross?" It's "what will it net, and is that number still interesting after I've paid for everything?"

Platform revenue projections are estimates, not guarantees: Airbnb, VRBO, and third-party tools like AirDNA generate projections based on comparable listings in the area. Those estimates assume your property is well-photographed, well-reviewed, competitively priced, and actively managed. They also don't account for your specific expense structure, regulatory environment, or the time it takes a new listing to build reviews and ranking. Treat them as a rough ceiling, not a floor.


Occupancy: what the data shows vs. what you'll actually see

The West Michigan lakeshore is a genuinely seasonal market. The demand concentration into summer is more pronounced here than in year-round destinations, and your financial model needs to reflect that accurately.

Peak season on the lakeshore runs roughly Memorial Day through Labor Day. During those weeks, a well-positioned property with strong reviews and good photography can achieve very high occupancy, sometimes 90% or better. That concentration is also why the gross revenue numbers from peak season look attractive in isolation.

The shoulder seasons are a different story. May and September see meaningful demand, particularly around holiday weekends, and fall color season in October brings some occupancy. But November through April is largely slow, and carrying costs don't stop during those months. A property that books 85% occupancy in July may average 20 to 30% over the full year when the off-season is included. Annual occupancy for a solid lakeshore STR tends to run somewhere between 45 and 65 percent, with wide variance depending on location, property type, and how actively it's managed.

When you're evaluating a property that's currently operating as an STR, ask for actual booking data, not projections. Twelve months of actual occupancy and gross revenue tells you far more than any estimate. If the seller or management company can't or won't provide it, that's worth noting.

What "already operating as an STR" actually tells you: A property with a track record is genuinely valuable data, but it reflects the performance under the prior owner's management, pricing strategy, listing quality, and review history. A new owner starting a listing from scratch won't inherit those reviews. Expect a ramp period of six to twelve months before a new listing performs comparably to an established one in the same market.


The full expense picture

Here's where most proformas fall short. They capture some expenses but not all of them, and the ones that get omitted tend to be the ones that compound over time. Below is the full list of expense categories that belong in any honest financial model for a West Michigan lakeshore STR.

  • 1 Platform fees: Airbnb charges hosts roughly 3% per booking. VRBO's fee structure varies depending on whether you're on a subscription or per-booking model, but falls in a similar range. These come directly off the top of gross revenue before you see any of it.
  • 2 Property management: Full-service STR management in the Southwest Michigan market typically runs 20 to 30% of gross rental revenue. This covers guest communication, check-in coordination, turnovers, and maintenance response. If you're not local, this is a real cost, not optional. Some owners self-manage to save the fee, but doing it well from Chicago requires more active involvement than most people expect.
  • 3 Cleaning and turnover: Cleaning fees are generally passed to guests on major platforms, but the actual cost of servicing a lakeshore property through a busy summer is higher than a flat cleaning rate implies. Linen service, restocking of consumables (toiletries, paper goods, kitchen basics), and the deeper post-season clean add cost over the course of a year that doesn't always show up in a per-booking line item.
  • 4 Maintenance and repairs: Rental properties wear faster than owner-occupied homes. Appliances run constantly, outdoor furniture takes abuse, HVAC systems work harder, and things break with guests in residence. A realistic maintenance reserve for an active STR is 2 to 3% of property value annually, not the 1% rule of thumb for owner-occupied homes. That reserve needs to be in your model from day one, not added after the first major repair.
  • 5 Property taxes: Property taxes on the lakeshore vary significantly by township and municipality. Some communities have high millage rates, and lake-adjacent properties are assessed at values that reflect the premium buyers pay, not the income the property generates. This is a fixed carrying cost that runs twelve months a year regardless of occupancy. Build in the actual tax bill for the specific property, and don't assume it will be lower than what you're used to paying elsewhere.
  • 6 Insurance: Short-term rental insurance is not the same as a standard homeowner's policy. You need a policy that covers commercial rental activity, and those policies carry a meaningful premium over standard coverage. Some standard policies will deny claims if they discover the property was being rented short-term at the time of the loss. Get a quote specific to STR use before you close, not after.
  • 7 Utilities: Even if guests pay a utilities surcharge, you as the owner carry the base cost of keeping a property habitable year-round. Heat in winter, water service, internet (guests expect it, a slow connection generates bad reviews), trash service, and any HOA or association dues all run continuously.
  • 8 Licensing fees and local taxes: Many lakeshore municipalities charge an annual STR license fee. Michigan's 6% state lodging tax, plus any applicable county or township transient occupancy taxes, are typically collected and remitted through the platforms, but confirm this for the specific jurisdiction you're buying in, as enforcement and collection practices vary.
  • 9 Mortgage debt service: If you're financing the purchase, your monthly principal and interest payment is a fixed cost that runs regardless of occupancy. Investment property loans typically carry rates higher than primary residence or second home loans, and require 20 to 25% down. Model your actual debt service, not a generic rate estimate.

How regulations affect your revenue model

The regulatory environment in West Michigan doesn't just affect whether you can operate. It affects how much you can earn from the operation, and in ways that often don't show up in a standard proforma.

Minimum night requirements reduce your ability to fill short-gap dates between longer bookings. A township that requires a three-night minimum eliminates a large portion of the weekend bookings that would otherwise fill in around your weekly stays. That directly affects occupancy in the shoulder seasons, which is already your weakest period.

Occupancy caps, where they exist, limit how many guests can be on the property at one time. For a property that derives part of its premium from the ability to accommodate large groups, a guest cap at a number lower than the bed count can affect your rate ceiling.

Owner-occupancy requirements, where they apply, may require you to be present during rentals or to reside in the property for a minimum number of days per year. If your investment model involves being fully absent while the property operates, any owner-occupancy requirement changes that model significantly.

And beyond the current regulations, there's the ongoing risk that the rules change. A municipality that permits unrestricted STR operation today can impose new restrictions at any future meeting. You need to evaluate not just the current regulatory picture but how quickly it has been moving in the communities you're considering, and build your financial expectations around a range of possible futures, not just the current status.

What belongs in the financial model

A sound STR financial model starts with conservative assumptions and pressure-tests them against the downside, not the upside. That analysis belongs with your CPA or financial advisor, who can apply your actual tax situation, financing terms, and risk tolerance. What follows is an illustrative structure, using a hypothetical four-bedroom lakeshore property with deeded lake access purchased at $850,000 with 25% down, to show what a complete model needs to include.

Line Item Annual
Revenue
Gross rental revenue (50% occupancy · avg $425/night) $77,625
Less: platform fees (~3%) ($2,329)
Net revenue to owner $75,296
Operating Expenses
Property management (25% of gross) ($19,406)
Cleaning / linen / consumables ($6,500)
Maintenance reserve (2% of value) ($17,000)
Property taxes (estimate; verify for specific parcel) ($9,500)
STR insurance ($3,800)
Utilities (heat, water, internet, trash) ($4,200)
Licensing fees & miscellaneous ($800)
Total operating expenses ($61,206)
Debt Service
Mortgage (25% down · ~7.5% investment rate · 30yr) ($44,828)
Annual cash flow (before income tax) ($30,738)

This example is illustrative only and is not financial advice. Every variable, including purchase price, interest rate, actual occupancy, nightly rate, tax assessment, and management cost, will differ for a specific property. Work through the actual numbers with your CPA or financial advisor before making any investment decision.

That example is not designed to scare you away from lakeshore STRs. It's designed to show you that the math requires honest inputs to be useful. A property with stronger occupancy, a higher nightly rate, a lower purchase price, or owned free and clear looks very different than the above. So does a property with lower occupancy, a higher tax bill, or heavier management costs. The model only works if the numbers in it are real.

What changes the math most: The biggest levers in the proforma are purchase price, financing structure, management cost, and actual occupancy. A property bought at a reasonable price with strong cash equity, self-managed or managed efficiently, with real documented occupancy history, can absolutely produce meaningful net income. The properties that disappoint buyers are usually ones where any one of those inputs was assumed rather than verified.


When the numbers actually work

There are lakeshore STRs that perform well. The ones that do tend to share a handful of characteristics.

Direct lake access or strong lake proximity is the clearest driver of both nightly rate and occupancy on the West Michigan lakeshore. Properties with private frontage or deeded association access command rates that make the expense structure more manageable. Properties that are marketed as "a short drive to the lake" are competing in a different and more crowded market.

Bedroom count matters. A four-bedroom property that can comfortably sleep eight to ten guests generates fundamentally different economics than a two-bedroom. The ability to justify higher nightly rates and to attract group bookings is what makes the revenue side of the proforma hold up against the fixed costs.

Properties that were purchased at reasonable prices relative to their actual rental income potential have an obvious structural advantage. Some lakeshore properties are priced based on what buyers are willing to pay for personal use, which is sometimes a premium over what the rental economics would support. Buying a property at a valuation that requires perfect occupancy and top-of-market rates every year to cash flow is a fragile position.

And the properties that work tend to be run seriously. Strong photography, competitive and dynamically-adjusted pricing, responsive guest communication, and consistent maintenance create the review base that drives ranking and repeat bookings. A well-run operation at a modest location will often outperform a poorly-run one at a better location.

The lakeshore STR market is real and there is genuine investment opportunity in it. But it rewards buyers who go in with clear eyes, verified numbers, and a realistic picture of what the operation actually requires. The buyers who get hurt are the ones who built their plan around the best-case scenario rather than the base case.

Thinking seriously about a lakeshore STR?

The financial analysis belongs with your CPA or financial advisor. What I can help with is everything on the real estate side: understanding exactly what a property offers in terms of lake access, bedroom configuration, and rental appeal; where it sits in the regulatory picture; and whether what it's priced at makes sense for the market. That conversation is worth having before you're deep in the process.
