The spreadsheet doesn't care about sentiment. Neither should you.
Second homes cost €200-300 per day in maintenance, taxes, insurance, and repairs—money that could generate better returns elsewhere. 71% of Spanish second-home buyers purchase for personal use, but experts argue rental investments offer better liquidity and regular income.
- Spain has approximately 3 million households with second residences
- Daily carrying costs for a 150,000-euro property: 200-300 euros
- 71% of second-home buyers purchase for personal use; only 22% rent long-term
- Nearly 70% of owners worry about security; 46.8% believe risk has increased
Investment specialist Carlos Galán warns that buying a second home at the beach is a major financial mistake, citing hidden costs of €200-300 daily and missed investment opportunities.
Nearly three million Spanish households own a second home, according to national statistics. For most of them, a beach or mountain property represents something deeper than real estate—it's a symbol of arrival, a place to gather family, a refuge from ordinary life. But investment specialist Carlos Galán has spent enough time running the numbers to see something else entirely: a financial trap disguised as a dream.
Galán, who built a following online discussing real estate strategy, doesn't mince words. Buying a second residence in a desirable location is, in his view, one of the largest financial mistakes a person can make. The reasoning is straightforward but often overlooked. A property valued at 150,000 euros carries hidden costs that most buyers never fully calculate—somewhere between 200 and 300 euros every single day, even on days you don't visit. Property taxes, insurance premiums, maintenance, repairs, homeowners' association fees, utilities. The arithmetic compounds quickly. Over a year, that's roughly 73,000 to 110,000 euros in expenses for a house you might occupy for a few weeks.
But the real damage, Galán argues, isn't the daily bleed of cash. It's what that money could have become if it had been deployed differently. The same capital invested in rental properties generates monthly income. Funneled into investment funds or small businesses, it produces returns. Locked into a second home that sits empty most of the year, it produces nothing—except the illusion of wealth. You are paying for the privilege of owning something you barely use.
Who buys these properties anyway? Research from real estate platforms paints a clear picture: typically middle-aged men from the upper-middle class. Seven out of ten purchase for personal use—family vacations, weekend retreats, a place to remember good times. Only 22 percent rent them out long-term, and just 7 percent pursue short-term vacation rentals. Security concerns loom large; nearly 70 percent of owners worry about theft or break-ins, and almost half believe the risk has worsened in recent years. The emotional weight of ownership is real. So is the financial weight.
Galán's own strategy inverts the conventional wisdom. He invests in properties specifically to rent them out. The income from those rentals funds his leisure—hotel stays, apartment rentals, the freedom to travel without being tethered to a single property. This approach offers what a second home cannot: liquidity, regular cash flow, diversification, and the ability to walk away without loss. A second residence, by contrast, carries the risk of depreciation, the burden of constant maintenance, and the dead weight of carrying costs during months of vacancy.
The emotional dimension runs deeper than most people admit. Galán observes that many buyers are chasing status or nostalgia—the memory of a perfect vacation, the feeling of having "made it." These are human impulses, entirely understandable, but they are terrible guides for financial decisions. The spreadsheet doesn't care about sentiment. Neither should you.
When Galán works with clients evaluating rental scenarios, he insists on cold analysis. One student considered renting a property to teachers during the academic year and switching to vacation rentals in summer. The summer income looked attractive on the surface. But when the numbers were entered into a calculator—accounting for the tax deductions available for long-term rentals versus the higher gross revenue from short-term bookings—the picture shifted. The vacation rental generated more gross income but less net profit after taxes. Factor in the additional management burden, the higher turnover, the complications of coordinating multiple guests, and the long-term rental strategy became the smarter choice. The lesson: intuition and forum gossip are worthless. Data, realistic assumptions, and scenario comparison are everything.
For anyone considering a second home, the question isn't whether it feels right. The question is whether the numbers work. And for most people, they don't.
Notable Quotes
Buying a house at the beach or in the mountains is one of the biggest mistakes you could make. It may be one of your biggest dreams, but it's a financial error.— Carlos Galán, investment specialist
That money cannot be directed toward much more profitable investments. You could be generating significant returns in other assets instead of immobilizing it in a property you'll barely use.— Carlos Galán
The Hearth Conversation Another angle on the story
Why do you think people keep buying second homes if the math is so clearly against it?
Because the math isn't what drives the decision. People buy them for the feeling—status, nostalgia, family memories. The financial analysis comes after, if at all. By then, they're already emotionally committed.
But surely some people do make money from vacation rentals?
Some do, but not as many as they think. The summer months look spectacular until you account for taxes, management time, and the fact that you can't rent it when you want to use it yourself. The numbers rarely match the fantasy.
What about just renting it out year-round to long-term tenants?
That's closer to rational. You get steady income, tax advantages, and less headache. But you're still paying 200 to 300 euros a day in carrying costs. You need the rental income to exceed that—and it usually doesn't, not enough to justify the capital tied up.
So what's the alternative for someone who wants a vacation home?
Rent when you need it. Stay in hotels, book apartments, use your capital to generate income elsewhere. You get the vacation without the anchor. You keep your money working for you instead of working against you.
Doesn't that feel less like ownership?
It does. And that's the real cost—not financial, but psychological. You're giving up the status symbol. For most people, that's worth more than the money they'd save.
