Palm Springs used to be full of condos owned by retired couples who rented them out a few weeks a year, mostly as a tax write-off. Then Airbnb arrived around 2015, and everything got recalculated. A house pulling $3,200 a month on a normal lease could suddenly earn triple that over a strong July. California investors noticed fast, and the math looked great on paper. What often gets left out is what happens when the math is wrong — an overpriced property, a pool nobody uses after October, and a January that barely covers the electric bill.
Anyone who has owned a beach house in San Diego County knows the swing: summer pays the mortgage for the year, while February barely covers the gardener. That volatility is the whole game. Understanding it separates investors who build real wealth from those who sell at a loss after two rough winters.

Why Short-Term Rentals Still Pencil Out
Santa Monica and San Francisco cracked down on short-term rentals, pushing money toward looser markets like Big Bear, Joshua Tree, and the Central Coast. But city councils change their minds, so nothing about that freedom is guaranteed. Smart investors track occupancy, real nightly rates once a listing has reviews, and whether tourists show up year-round or only in summer. Cap rates on vacation properties often run higher than traditional rentals, sometimes by two or three points, because the work is heavier - turnover cleaning, late-night guest messages, and emergency repairs that never make it into a simple spreadsheet.
Readers wanting the broader rental math framework may want to review an earlier piece on real estate investing basics first.
Picking the Right Market
Coastal towns like Cambria and Carpinteria command higher rates but face tighter permitting; frozen permit counties make existing permits more valuable. Mountain towns like Big Bear and South Lake Tahoe get two peak seasons - skiing and boating - filling calendars twice as often as beach towns that go quiet after Labor Day.
Outside California, markets like Wisconsin's Lake Geneva draw steady Chicago money, with lakefront listings behaving very differently from inland ones, and winter visitors smoothing out revenue that purely seasonal California markets lack.
Looking Outside California
Not every high-yield opportunity sits inside state lines. Many California investors are now buying second-home rentals in the Midwest and Mountain West, where entry prices are lower and cap rates run higher. Wisconsin's Lake Geneva area is one such market, long favored by Chicago money and summer crowds dense enough to book out well-run rentals months ahead.
Investors typically start by browsing available listings around Geneva Lake, since near-lake properties behave differently, and winter visitors add revenue California summer markets rarely see.
Financing and the Numbers That Matter
Lenders treat rental income differently than lease income; some require two years of history before counting it. A useful rule: if a property can't cash flow at 60% occupancy with conservative rates, the deal's too tight. Wildfire-driven insurance costs are also rising sharply, with some carriers exiting California entirely, pushing owners toward costlier, thinner FAIR Plan coverage.
Managing Without Losing Every Weekend
Resort-town property managers charge 20–30% of gross income, versus 8–10% for long-term rentals - steep, but often worth it. Some owners split duties themselves, keeping more revenue but taking on more work.
The Bottom Line
Vacation rentals reward investors who treat them as a business, not a lifestyle purchase. Know the occupancy floor, price insurance realistically, and never assume every year matches the last.
