Full analysis: San Mateo County vs Santa Clara County

On the money side of this comparison — what a listing actually earns against the nights it has available — San Mateo County finishes clearly ahead of Santa Clara County. Revenue per available night — rate and occupancy combined, the figure that actually reaches an owner — is 112.3% higher in San Mateo County: £49 against £23. San Mateo County commands 40.6% more per night, £200 against £142. Those gaps are wide enough to survive a normal year's variance.

San Mateo County takes both halves of the yield equation, which is less common than it sounds. It charges more per night — £200 against £142 — and still fills more of the year, 24.7% against 16.4%. A market that leads on price and utilisation at once is normally one where demand has outrun supply, rather than one where hosts are discounting to keep the calendar busy. RevPAR reflects the double advantage at £49 against £23.

That verdict needs a caveat, because Santa Clara County is not simply the weaker market of the two. Santa Clara County is the deeper market at 4,454 active listings against 2,237, which usually means better comparables going in and a wider buyer pool coming out. Santa Clara County's calendar is the flatter of the two — 21.3 points between its best and worst month against 28.4 in San Mateo County — which makes debt service easier to underwrite. If your model leans on that dimension, the ordering above can reasonably flip.

Neither San Mateo County nor Santa Clara County currently has a verified short-term rental regulation record in our register, so the comparison above is a yield comparison only. Regulation is the single largest source of downside in this asset class — an unverified market is an unpriced risk, not an absent one.

The two calendars also behave differently. San Mateo County peaks in October at 57.8% and bottoms in February at 29.4%; Santa Clara County runs from 53.9% in October down to 32.6% in February. Santa Clara County is the steadier of the two at 21.3 points peak-to-trough against 28.4 — easier to underwrite against a mortgage — while San Mateo County concentrates its return into a shorter window and rewards operators who price the peak aggressively instead of holding a flat rate all year.

Who each suits, then. San Mateo County suits buyers who want a conventional, lightly regulated entry. It is also the momentum side of this pair. Santa Clara County answers to the same regulatory profile, so the split between them is operational rather than legal. Every figure above comes from the same Inside Airbnb snapshot pipeline on both sides, dated 2026-09, filtered to listings with at least one booking in the last twelve months. Occupancy medians are drawn from 2,237 active San Mateo County listings and 4,454 in Santa Clara County.
