Maine vs Cape Cod: Coastal Second Home Cost

A $750,000 coastal cottage in Bar Harbor and an $850,000 Cape Cod saltbox sit on the same Atlantic seaboard, four hours apart by car. Run both through a total cost of ownership model at the 7.60% second home mortgage rate Curinos reported for April 2026, and the gap between them is not what most buyers expect: the cheaper Maine property carries a lower net cost per dollar invested, largely because its short-term rental market runs hotter than the Cape’s.

This analysis models annual total cost of ownership and the vacation home net carry rate for two representative coastal second homes — one on Mount Desert Island in Maine, one on Cape Cod in Massachusetts. The purchase prices are modeled scenarios chosen to reflect what a $150k+ household actually shops in each market, not market medians. Every rate, fee, and revenue figure is sourced and dated below.

The headline numbers

Five figures define the comparison. The mortgage rate applies to both; the revenue and net carry rate diverge sharply.

What rental income each market actually produces

The rental gap is the engine of this comparison, so start there. AirDNA reports the Bar Harbor short-term rental market at 74% occupancy with a $444 average daily rate, and the Provincetown market — the strongest short-term rental submarket on Cape Cod — at 57% occupancy with a $499 average daily rate, both as of late 2025. Higher nightly rate, lower occupancy: the Cape charges more per night but fills fewer of them.

Translating market-level daily rate and occupancy into an annual gross figure requires assumptions AirDNA’s headline monthly numbers don’t carry cleanly, because peak-month revenue cannot be multiplied by twelve in a market this seasonal. Model-specific annual revenue for these exact price points was unavailable, so I built a defensible annual estimate from occupancy-adjusted booked nights at each market’s average daily rate, then discounted for the off-season collapse both coasts share. That yields roughly $72,000 gross for the Maine property and $66,000 for the Cape property. Treat these as segment averages, not guarantees — the gap between AirDNA income potential and real ownership cost is wide enough that conservative modeling matters.

Maine’s edge comes from utilization. Bar Harbor’s 74% occupancy reflects Acadia National Park drawing visitors across a longer shoulder season; the Cape’s summer-concentrated demand leaves more empty calendar. The same dynamic shows up in whether second home rental income can cover the costs generally: occupancy, not nightly rate, usually decides the outcome.

Building the total cost of ownership

Gross revenue is the easy part. The carrying cost stack is where second homes quietly drain capital. Both properties assume 20% down, leaving a $600,000 mortgage on the Maine home and a $680,000 mortgage on the Cape home at the 7.60% second home mortgage rate Curinos reported for April 2026.

Sources: mortgage payment derived from Curinos second home rate, April 2026; property tax from Tax Foundation effective rates (Maine 0.98%, Massachusetts 1.07%), 2026; maintenance at 1.5% per Finluxy cluster methodology; property management at 25% of gross rental revenue (midpoint of 20–30% industry range). Insurance, utilities, and travel are modeled estimates for coastal second homes.

Property tax separates the two markets less than the price difference suggests. Maine’s 0.98% effective rate and Massachusetts’s 1.07% effective rate, both per the Tax Foundation’s 2026 data, are close enough that the Cape’s higher bill comes mostly from its higher assessed value, not a punitive rate. The property management fee for second homes is the larger swing factor — at 25% of gross, Maine’s stronger revenue paradoxically generates a higher management bill in absolute dollars.

The net carry rate, calculated

Total cost of ownership in isolation flatters the cheaper property and tells you little about efficiency. The Finluxy Vacation Home Net Carry Rate corrects for both. It expresses annual net carrying cost — TCO minus net rental income — as a percentage of purchase price, so a $750,000 home and an $850,000 home become directly comparable on a per-dollar-invested basis.

Net rental income is gross revenue minus the management fee already embedded in TCO, so to avoid double-counting, the calculation nets gross revenue directly against gross TCO. Maine: $99,756 TCO minus $72,000 gross revenue leaves $27,756 net carry, divided by $750,000, times 100. Cape Cod: $109,181 minus $66,000 leaves $43,181, divided by $850,000, times 100.

Source: Finluxy calculation from the TCO and revenue figures above. Net carry rate = (gross annual TCO − gross rental revenue) ÷ purchase price × 100. Positive value indicates net cost.

Both numbers are positive, meaning neither property pays for itself — expected for second homes at this rate environment. But Maine’s 3.7% net carry rate against the Cape’s 5.1% means the Maine owner spends about $14,000 less per year out of pocket on a property that also costs $100,000 less to buy. The headline summary block above shows slightly higher rates (4.6% and 5.7%) because those figures fold in a vacancy and revenue-haircut sensitivity; the table here uses the unadjusted model. Both versions tell the same story.

The IRS 14-day rule changes everything

Every figure above assumes the property is taxed as a rental, with management fees, maintenance, and depreciation deductible against rental income. That assumption holds only if personal use stays within the IRS limit. Under IRS Publication 527 (2025), if personal use exceeds the greater of 14 days or 10% of the days the property is rented at fair market value, the property is classified as a personal residence — and deductible rental expenses get capped at rental income, killing the loss deductions that make the after-tax math work.

For a Cape Cod home rented 100 days, the personal-use ceiling is 14 days, because 10% of 100 is only 10 and the rule takes the greater figure. Spend three weeks there yourself and the tax treatment flips. A household buying a coastal second home specifically to enjoy it faces a direct trade-off between personal use and deductibility — the tax math behind the IRS 14-day rule deserves its own modeling before purchase, not after.

What most coverage misses

Comparison articles fixate on purchase price and nightly rate. The dataset here shows the decisive variable is occupancy, and it runs counter to prestige. Cape Cod commands a $499 average daily rate to Bar Harbor’s $444 — the Cape “looks” like the premium market on a per-night basis. Yet Bar Harbor’s 74% occupancy against the Cape’s 57% (both AirDNA, late 2025) more than erases that nightly premium over a full year. The market with the lower sticker glamour and lower nightly rate produces the better net carry rate, because Acadia keeps the calendar full deeper into the shoulder seasons while the Cape’s demand stays bunched into a short summer.

The implication for a buyer: a coastal second home’s economics are set less by the price you pay or the rate you can charge than by how many nights you can actually fill. That reframes the whole rent-vs-own question away from the listing photos and toward the booking calendar.

What this means for a $150k+ household

At a $150k+ income, neither property is a wealth-builder on these numbers — both carry a net annual cost in the high four to low five figures. The decision is about lifestyle value per dollar of net carry, not yield. A household clearing $150,000 can absorb Maine’s roughly $28,000 net carry more comfortably than the Cape’s $43,000, and the lower entry price preserves more capital for the down payment cushion these stricter second home loans demand.

Two thresholds matter most at this income. The first is the 14-day personal-use line: a household that wants real summer use of the home should model the personal-residence tax scenario, not the rental scenario, because crossing that line can swing the after-tax cost by several thousand dollars a year. The second is the financing premium — the 7.60% second home rate Curinos reported for April 2026 runs well above primary-residence pricing, and the second home mortgage rate premium compounds across a 30-year term into the single largest line in the TCO stack. Buyers comparing coastal markets against mountain or lake alternatives — the year-round breakdown of lake house ownership cost uses the same framework — should run the net carry rate for each before falling for any single market’s view.
