Full analysis: San Mateo County vs Seattle

Seattle finishes clearly ahead of San Mateo County on our composite of occupancy, revenue per available night and regulation risk — and it is the calendar rather than the price tag doing the work. Seattle's listings run at 32.9% occupancy against 24.7% in San Mateo County, worth 8.2 extra points of booked calendar every year. Seattle turns its rate and occupancy into £55 per available night against £49 in San Mateo County, a 12.2% edge on the only yield figure that nets the empty nights out. Those gaps are wide enough to survive a normal year's variance.

The two markets reach their revenue by different routes, which is what makes this pairing worth reading rather than just tabulating. San Mateo County is the rate market: £200 a night against £184, some 8.4% more, but it converts fewer of those nights at 24.7% occupancy. Seattle is the volume market, filling 32.9% of its calendar at a lower headline price. Revenue per available night settles it: £55 in Seattle against £49. Rate is what you advertise; RevPAR is what you bank.

That verdict needs a caveat, because San Mateo County is not simply the weaker market of the two. San Mateo County prices modestly above Seattle — £200 a night to £184, about 8.4%. The twelve-month direction favours San Mateo County too: occupancy there moved +1.7 points while Seattle moved −1.6 points. If your model leans on nightly rate rather than volume, the ordering above can reasonably flip.

Neither San Mateo County nor Seattle 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%; Seattle runs from 59.2% in September down to 31.4% in February. Both swing by a similar amount across the year, so neither offers meaningfully steadier cash flow than the other.

Who each suits, then. San Mateo County suits buyers who want a conventional, lightly regulated entry and who can hold rate through the shoulder season rather than discounting to fill the calendar. It is also the momentum side of this pair. Seattle answers to the same regulatory profile, so the split between them is operational rather than legal: it is the market for an owner whose economics survive high turnover — more bookings, more cleans, more guest contact per pound of revenue. It is the contrarian side: buying it means buying a market that has cooled. 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 5,958 in Seattle.

Frequently asked questions

Is San Mateo County or Seattle better for Airbnb investment?
Seattle, on the data we track. It leads on higher occupancy (32.9% vs 24.7%), stronger RevPAR (£55 vs £49), and a deeper market (5,958 vs 2,237 active listings). San Mateo County is not the weak side of this pair, though — it wins on a higher nightly rate (£200 vs £184).
Which has higher occupancy, San Mateo County or Seattle?
Seattle, at 32.9% median occupancy against 24.7% in San Mateo County — a gap of 8.2 points. That is a real but modest edge; a well-run listing in San Mateo County can close most of it. Over the last twelve months San Mateo County gained 1.7 points and Seattle shed 1.6 points, so the gap is closing.
Which has higher nightly rates, San Mateo County or Seattle?
San Mateo County, at £200 a night against £184 in Seattle — roughly 8.4% more. The nightly rate is not the whole story, though. On revenue per available night — rate multiplied by how often the room actually sells — Seattle comes out ahead at £55 against £49, so Seattle's cheaper nights are more than repaid by how often they fill.
Which has stronger year-over-year growth, San Mateo County or Seattle?
San Mateo County, on occupancy: +1.7 points over the last twelve months against −1.6 points in Seattle. Nightly rates rose 59.1% in San Mateo County and rose 60.9% in Seattle over the same window. One year of movement is a direction, not a trend — weigh it against the regulation picture before treating it as momentum.
Which is the bigger Airbnb market, San Mateo County or Seattle?
Seattle, with 5,958 active listings against 2,237 in San Mateo County. Size cuts both ways: a deep market gives you comparables, contractors and an exit, while a thinner one means fewer near-identical rivals competing for the same search results.
How much can you earn from an Airbnb in San Mateo County vs Seattle?
Seattle earns more: roughly £20,063 a year for a median listing against £17,870 in San Mateo County. Those are gross booking revenues before cleaning, management, platform fees, furnishing amortisation and tax — budget for a meaningful share of them, and note that a median listing is a median operator, not a good one.
