Barnstable County

Barnstable County posts a 2.66% cap rate against a $757,449 median home price, with monthly rent coming in at $2,578. The gross rent-to-price ratio of 0.0408, or about 0.34% per month, sits well below the 1% rule threshold that most cash-flow buyers use as a minimum screen. At a 6.85% mortgage rate with 20% down, the model spits out a monthly mortgage of $3,971 and estimated total expenses of $902, producing negative $2,295 in monthly cash flow and a cash-on-cash return of negative 15.81%. These are not marginal numbers. This is a deeply appreciation-oriented market, and the math makes that unavoidable.

The appreciation score of 79 out of 100 tells you who Barnstable is actually suited for: an investor with a multi-year hold horizon who can carry negative cash flow and believes in the long-term price trajectory of Cape Cod real estate. Home prices grew 2.91% year-over-year, which is moderate but meaningful on a $757,000 base. The cash-flow score of 31 confirms there is no realistic path to positive cash flow at current prices and rates without a large equity position well beyond the modeled 20% down, a significant below-market acquisition, or a value-add component that meaningfully boosts rent. A value-add operator who can push rents on an underutilized property, or convert a single-family to accommodate legal accessory dwelling unit income, has more of a case here than a straight buy-and-hold landlord underwriting at market. The affordability index of 8 out of 100 signals that tenant demand is not driven by affordability; this is a premium market with premium entry costs.

The taxInsurance data adds an important layer to the carry story. At the Massachusetts state-average effective rate of 1.23%, property tax alone runs an estimated $9,317 annually on this price point, with insurance adding another $1,969, putting combined tax and insurance at $941 per month. That figure is worth staring at: it represents more than a third of the gross rent collected each month. The 1.23% rate is flagged as normal relative to other states, so this is not an outsized tax burden by national standards, but in the context of a market where rents barely cover operating costs before debt service, $941 in monthly tax and insurance has real weight on the underwrite. Note that 1.23% is a state-average estimate per Tax Foundation 2024 data, and actual rates at the county or township level may differ.

Barnstable's risks are structural and concentrated. The county's economy is anchored in tourism and seasonal activity, which creates inherent rental demand seasonality. A landlord leasing year-round in an area where a meaningful share of housing stock cycles through short-term vacation rental use faces both competition for tenants and local regulatory exposure, as Massachusetts municipalities have moved to restrict short-term rentals in some areas. The affordability index of 8 reflects how far median home prices have stretched beyond what typical earners can absorb, which caps the pool of long-term buy-side demand and, by extension, puts the appreciation thesis partially at risk if rate conditions or remote-work migration patterns reverse. Population of 229,436 makes this a mid-size county, but it is geographically and economically distinct from the Boston metro, meaning it does not benefit from the same job-market depth or institutional demand floor.

Compared to its neighbors, Barnstable is the weakest performer on nearly every investable metric. Suffolk County (Boston) carries a similar median price of $747,013 but generates $3,307 in median rent and a rent-to-price ratio of 0.0531, yielding an overall score of 45 versus Barnstable's 43. Middlesex at 0.0439, Essex at 0.0443, and Norfolk at 0.0458 all post better rent-to-price ratios at comparable or lower price points. Bristol County is the clearest contrast: $524,316 median price, a 0.0466 rent-to-price ratio, and an overall score of 49, the highest of any neighbor shown. An investor primarily concerned with cash-flow mechanics and entry price should look at Bristol before Barnstable. The one argument for choosing Barnstable over any of these neighbors is a concentrated bet on Cape Cod's scarcity story, specifically the thesis that constrained land supply, continued second-home demand, and the appeal of coastal Massachusetts real estate will sustain appreciation over a 7-to-10-year hold. That is a real thesis, but it is a speculative one, and it requires the investor to fund roughly $27,540 in annual negative cash flow at the modeled assumptions while waiting for it to play out.
