Why Investors Consider Williams Bay

Williams Bay attracts STR investors because of its concentrated lakefront tourism demand and limited supply, creating a niche market where well-positioned properties can earn strong summer returns.

Expert Market Assessment

"Williams Bay earns an "Attractive Opportunity" designation, driven by a niche lakefront market where limited inventory and strong summer demand create favorable conditions for well-run properties. Seasonality is the defining feature here — July and August together account for nearly 36% of total annual revenue, while winter months dip below $2,600. This makes cash-flow planning essential; investors who can absorb quieter months will benefit from outsized summer performance. The market's average metrics sit below Wisconsin state averages for ADR ($296 vs. $368) and occupancy (27% vs. 38%), but this reflects the seasonal nature of a lake destination rather than weak fundamentals."

Key Airbnb Metrics & Trends in Williams Bay

Average revenue by month in Williams Bay

Williams Bay exhibits extreme seasonality: July leads at $10,029 in average monthly revenue — nearly five times the January low of $2,108 — with August close behind at $9,458. Investors should expect roughly 60% of annual revenue to concentrate in the May-through-September window, making summer performance critical to overall returns.

Active Airbnb listings by property size in Williams Bay

Three-bedroom homes dominate supply with 10 of the 25 active listings, followed by 2-bedrooms at 7 and 4-bedrooms at 5. The absence of 1-bedroom or 5+ bedroom listings could signal either limited demand for those configurations or a potential gap worth exploring for investors with the right property.

Average daily rate (ADR) by property size in Williams Bay

ADR climbs sharply with size: 2-bedroom units average $243 per night, 3-bedrooms reach $272, and 4-bedroom properties command a substantial $376 — a 55% premium over 2-bedrooms. The jump to 4 bedrooms suggests strong willingness among groups and families to pay more for space in this lake vacation market.

Average RevPAN by property size in Williams Bay

Three-bedroom properties deliver the strongest RevPAN at $92 per available night, nearly double the $48 for 2-bedrooms and well ahead of the $50 for 4-bedrooms. This indicates that 3-bedroom units strike the best balance between nightly rate and occupancy, making them the most efficient revenue generators on a per-night basis.

Average occupancy rates by property size in Williams Bay

Occupancy rates vary widely by size: 3-bedroom properties lead at 34%, 2-bedrooms fill 20% of available nights, and 4-bedroom homes lag at just 13%. The low occupancy for 4-bedrooms suggests these larger properties rely on fewer, higher-value bookings rather than consistent turnover, which can create lumpier cash flow.

Average monthly revenue by property size in Williams Bay

Four-bedroom properties top the monthly revenue chart at $5,973 per month on average, despite their low occupancy, thanks to their premium ADR of $376. Two- and 3-bedroom units earn similar monthly amounts ($4,043 and $3,966, respectively), with the 3-bedroom edge in RevPAN offset by its lower nightly rate compared to 4-bedroom homes.

Average annual revenue by property size in Williams Bay

On an annual basis, 4-bedroom properties are the clear top earners at $71,680 — roughly 48% more than the $48,525 generated by 2-bedroom units and 51% above 3-bedrooms at $47,594. For investors targeting the highest gross revenue, larger lakefront homes offer the best return potential, though acquisition costs and maintenance expenses should be factored in.

Most common amenities for Airbnb listings in Williams Bay

Parking is universal at 100% of listings, and washer, dryer, and self check-in each appear at 96%, establishing these as table-stakes amenities in Williams Bay. Outdoor-focused features like BBQ grills (92%), outdoor furniture (84%), and patios (76%) reflect the lake-vacation character of this market, while lake access (32%) and beach access (24%) remain differentiators that could help a listing stand out.

Understanding Williams Bay's ROI Score: 58/100

Rabbu's ROI Score is a proprietary metric that evaluates short-term rental investment potential based on multiple factors.

How the ROI Score is Calculated

What This Means for Investors

Williams Bay's ROI score of 58 out of 100 places it in the "Attractive Opportunity" band, reflecting average performance across all four calculation factors — revenue-to-price ratio, occupancy stability, market growth trend, and supply/demand balance. No single factor stands out as exceptionally strong or weak, which suggests a balanced but not extraordinary investment profile where execution and property selection will matter more than market tailwinds alone. Investors should pair these metrics with thorough research into local STR regulations and property-level financial modeling before committing capital.

Short-Term Rental Regulations in Williams Bay

Understanding local STR regulations is essential before investing in Williams Bay. Here's the current regulatory landscape:

Permit Requirements

Williams Bay, Wisconsin may require short-term rental operators to obtain a permit or register with the village before listing a property. Investors should verify current requirements directly with the Village of Williams Bay and the Wisconsin Department of Revenue, as local STR ordinances can change.

Key Restrictions

Common STR restrictions in lakeside Wisconsin communities can include occupancy limits tied to bedroom count, noise ordinances, minimum parking requirements, and rules around boat dock or lake access usage. HOA covenants in residential neighborhoods may also impose additional limitations on rental frequency or guest behavior, so it's important to review any applicable association rules before purchasing.

Tax Obligations

Wisconsin requires short-term rental operators to collect and remit state sales tax and a room tax where applicable. Many booking platforms handle tax collection automatically, but hosts should confirm compliance with both state and local tax obligations in Williams Bay.

Regulations subject to change. Always verify with local authorities before purchasing. A Rabbu partner agent specializing in Williams Bay can provide current regulatory guidance.

Future Outlook & Long-Term Forecast

"Over the next 12–18 months, Williams Bay's STR market is expected to maintain its pronounced summer-driven seasonality, with peak revenues concentrated in July and August. Active listing counts grew 106% year-over-year, suggesting rising investor interest that could temper occupancy gains if supply outpaces demand. ADR may see modest increases of 1–3% as hosts refine pricing strategies for the peak lake season, though off-season occupancy — currently well below the state average — will likely remain a challenge without creative marketing or event-driven bookings. Investors should plan conservatively around 6–7 months of lighter revenue and budget accordingly."

How is Airbnb revenue calculated in Williams Bay?

The annual and monthly revenue figures for Williams Bay are derived from the trailing 12 months of historical booking performance for active comparable Airbnb listings in the market — they are not forward-looking projections.

This approach anchors the figures to what hosts have actually earned recently while naturally reflecting seasonal peaks and slower months, since each month uses its own historical performance data. Individual results can vary based on property quality, pricing strategy, and how actively the listing is managed.
