Cape Cod, MA.

In-depth analysis

Should you buy an STR in Cape Cod in 2026?

Yes, with town-specific underwriting. Cape Cod is one of the strongest seasonal STR markets in the country: $281 ADR, 62% occupancy, $174 RevPAR, 95/100 market score, tier-A saturation. Demand is drive-to from Boston, NYC, and the broader Northeast. The complication: “Cape Cod” is 15 towns, each with its own STR ordinance, registration regime, and code-enforcement posture. Underwriting starts with picking the town.

Regulation: where the city stands

• Massachusetts state STR registration — required statewide since 2019; state rental tax (5.7%) + local option (up to 6%) + community impact fee in some towns.
• Town-level ordinances — vary widely. Provincetown, Falmouth, Wellfleet, Truro, Chatham, Orleans, Yarmouth, Dennis, Brewster, Eastham, Harwich, Mashpee, Sandwich, Barnstable, Bourne each have their own rules.
• Community impact fee — adopted by some towns (3% on professionally-managed STRs).
• Wastewater Title 5 — Cape Cod has aggressive septic requirements that affect bedroom-occupancy caps.

See the MA DOR room occupancy tax registry and individual town clerk pages.

The market by the numbers

Submarkets that matter

• Outer Cape (Provincetown, Truro, Wellfleet) — premium pricing; cultural draw; Provincetown has the strongest year-round.
• Mid-Cape (Brewster, Orleans, Chatham, Harwich) — family leisure; premium SFR.
• Lower Cape / Upper Cape (Falmouth, Bourne, Sandwich) — closer to mainland; lower ADR; less seasonal.
• South Shore beaches (Dennis, Yarmouth) — family-density market.

The 3 mistakes buyers make here

1. Underwriting “Cape Cod” as one market. Each town’s ordinance, tax stack, and septic rules differ. Pick the town first, then the property.
2. Skipping the Title 5 septic review. Massachusetts septic rules cap bedroom occupancy and constrain renovation. Major variable.
3. Modeling year-round occupancy. Most of Cape Cod is summer-anchored. Outer Cape and Provincetown have year-round shoulder; the rest do not.

What to do next

• Identify the target town first; pull the town-specific ordinance and tax stack.
• Confirm Title 5 septic status and bedroom occupancy cap before EMD goes hard.
• Run Comp Analyzer within the same town.
• Get a bound STR + flood + wind insurance quote and use it in DSCR Loan Calculator.
• Use Year 1 Cash Needs with off-season carry modeled.
• Read Massachusetts STR Tax Stack 2026.
