Dennis, MA Airbnb Market Data, Statistics, and Occupancy Rates

Dennis Short-Term Rental Market Overview

Dennis, MA sits on Cape Cod's mid-section, drawing strong seasonal vacation demand that translates into a sharply peaked short-term rental market. With an average annual revenue of $55,664 across just 22 active Airbnb listings, the market is small but generates meaningful summer income — August alone averages $15,286 per listing. However, an average occupancy rate of 17% (well below the 44% state average) and home values averaging $1,133,585 mean investors need to be strategic about deal sourcing and off-season cost management.

Why Investors Consider Dennis

Investors are drawn to Dennis for its Cape Cod brand recognition and limited supply of short-term rentals, though high entry costs and deep seasonality demand careful underwriting.

Expert Market Assessment

"Dennis represents a competitive but narrowly seasonal opportunity. The market earns its ROI score of 54 out of 100 — labeled a "Competitive Opportunity" — largely because strong summer revenue must offset very lean winter months where listings average under $800. The spread between August's $15,286 and February's $732 is among the widest you'll see, underscoring that returns here hinge almost entirely on a three-to-four month window. For investors who can secure properties at favorable price points and keep carrying costs manageable during the off-season, the limited supply and Cape Cod's reliable draw create a viable path to positive returns."

Key Airbnb Metrics & Trends in Dennis

Average revenue by month in Dennis

Dennis exhibits extreme seasonality: August leads at $15,286 and July follows at $14,149, while the winter trough (February at $732, January at $788) represents just 5% of peak-month earnings. Investors should expect roughly 75% of annual revenue to concentrate between June and September.

Active Airbnb listings by property size in Dennis

The active supply in Dennis is notably small and concentrated, with just 7 three-bedroom and 5 two-bedroom listings tracked. The absence of one-bedroom, four-bedroom, and larger configurations could signal either regulatory constraints or limited demand for those sizes — or potentially an underserved niche worth exploring.

Average daily rate (ADR) by property size in Dennis

Three-bedroom properties command $304 per night compared to $265 for two-bedroom units, a modest 15% premium that may offer a favorable trade-off given the significantly higher occupancy rates for larger homes. Both sizes price well below the $479 market-wide ADR, suggesting a small number of premium or larger unlisted properties pull the overall average higher.

Average RevPAN by property size in Dennis

Three-bedroom listings deliver $61 in RevPAN versus just $13 for two-bedroom properties — nearly a 5x difference driven primarily by the occupancy gap between the two sizes. This stark contrast makes three-bedroom configurations the clear winner for revenue efficiency in Dennis.

Average occupancy rates by property size in Dennis

Three-bedroom units achieve 20% average occupancy while two-bedroom properties sit at just 5%, suggesting that family-sized vacation homes are far more aligned with guest demand in this Cape Cod market. The low two-bedroom occupancy raises questions about whether those units are priced out of demand or simply less attractive to the vacationing families that drive bookings here.

Average monthly revenue by property size in Dennis

Interestingly, two-bedroom and three-bedroom properties earn similar monthly averages — $3,293 and $3,141 respectively — despite the wide occupancy gap between them. The two-bedroom figure likely reflects higher nightly rates during the limited nights they are booked, though the three-bedroom's more consistent occupancy provides steadier cash flow.

Average annual revenue by property size in Dennis

Two-bedroom properties edge out three-bedrooms in annual revenue at $39,520 versus $37,692, though the difference is marginal. Given the much stronger occupancy profile of three-bedroom units, investors may find them a more reliable bet — with potential to outperform through better pricing optimization.

Most common amenities for Airbnb listings in Dennis

Every listed property in Dennis offers parking (100%), and near-universal amenities include a washer (96%), backyard, BBQ grill, dryer, and kitchen (all 91%) — reflecting a market geared toward self-sufficient family vacations. Beach access (23%) and waterfront (18%) remain differentiators rather than table stakes, meaning properties with direct water access likely command significant premiums.

Understanding Dennis's ROI Score: 54/100

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

Dennis earns a 54 out of 100 on Rabbu's ROI Score, placing it in the "Competitive Opportunity" band — meaning the fundamentals are there but require disciplined deal selection. The revenue-to-price ratio and occupancy stability both rate as average, while market growth trend scores below average, reflecting that rising listing counts haven't yet been matched by proportional demand gains. Investors should pair this data with thorough local regulatory research and conservative underwriting to account for the market's pronounced seasonality and high entry costs.

Short-Term Rental Regulations in Dennis

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

Permit Requirements

The Town of Dennis and the Commonwealth of Massachusetts may require short-term rental operators to obtain a permit or register with local authorities before listing a property. Investors should verify current requirements directly with the Dennis town clerk's office and the Massachusetts Department of Revenue.

Key Restrictions

Common restrictions in Cape Cod communities can include occupancy limits tied to bedroom count, minimum stay requirements (especially during peak summer months), noise ordinances, parking mandates, and HOA rules that may prohibit or limit rentals. Some towns also impose caps on the total number of STR permits issued, so confirming availability early in the acquisition process is advisable.

Tax Obligations

Massachusetts imposes a state room occupancy excise tax on short-term rentals, and municipalities like Dennis may levy an additional local occupancy tax. Platforms such as Airbnb often collect and remit these taxes on behalf of hosts, but operators should confirm compliance with both state and local tax obligations.

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

Future Outlook & Long-Term Forecast

"Over the next 12–18 months, Dennis is likely to see continued strong summer demand given Cape Cod's enduring appeal as a vacation destination, but the market's pronounced seasonality limits year-round income predictability. ADR may hold steady or edge up modestly in the $470–$500 range as supply remains tight at 22 listings, though the 234% year-over-year growth in active listings signals rising competition that could pressure occupancy during shoulder months. Investors should plan for revenue concentration between June and September, with off-peak months generating under $1,500 on average — a pattern that reinforces the need for conservative cash-flow projections."

How is Airbnb revenue calculated in Dennis?

The annual and monthly revenue figures for Dennis 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. We average each comparable listing's actual revenue per available night (RevPAN) by month over the past year, remove regional outliers, and aggregate the remainder into a market-level historical average. 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.
