“Buy-to-Let” on the Costa Blanca: Are You Sure the Numbers Work? (The Pretty Spreadsheet Trap)

“Buy-to-Let” on the Costa Blanca: Are You Sure the Numbers Work? (The Pretty Spreadsheet Trap)

Excel Smiles, Your Account Doesn’t: Something is Off

Typical scene. You see a villa in Benissa with an infinity pool, your bank agent gives you a good look, you open Excel, and boom!: 7% return. You already picture yourself in Moraira in August, mobile on airplane mode, bookings coming in effortlessly. Six months pass and your bank account tells a different story: a scraped, fought-for 3%, with sleepless nights and a channel manager you don't even know how to set up. Sound familiar?

The Costa Blanca is captivating. Sun, international demand, nearby airports, cheap flights—everything seems aligned. But there’s one piece nobody shows you on Instagram: the real operations and the invisible costs that blow up that pretty Excel. And no, it’s not bad luck. It’s the wrong method.

The Trap Nobody Admits: Confusing Gross with Reality

Let's get to the core. If you calculate “price per night × occupancy of the top Airbnb listing,” you are building a sandcastle. In 2025, with more regulated tourist licenses, professionalized competition, and increasingly demanding guests, playing "copy the rates" is like running with your shoelaces untied: you might move forward, but the fall hurts.

These are the holes where your profitability leaks out in the North Costa Blanca (Benissa, Calpe, Moraira, Benitachell):

  • Real season vs. annual illusion: full July and August don't fix an empty March. Long weekends barely save the day.
  • Professional Management: If you outsource tourist rental management in Costa Blanca, prepare for 18–25% of the income. And it is usually worth it.
  • Platforms: channel commissions, payment gateways, refunds, and price wars with the neighbour.
  • License and Regulations: urban compatibility, registration with the tourist housing registry, potential fees. Without this, the “tourist” rent is a risk, not a business.
  • Fixed Costs That Don't Forgive: IBI (property tax), garbage, community fees, insurance, internet, pool and garden maintenance (and no, the lemon tree doesn't water itself).
  • Replacements and Wear and Tear: sheets, towels, glassware, sunbeds, appliances... they break. It always happens.
  • Taxation: IRNR/IRPF, possible withholdings, and the great forgotten: taxes on profit, not on hope. Consult your case: EU/EEA, non-resident, etc.
“Your Excel is innocent; your assumptions are not.”

What It Looks Like… And What It Really Is

Most People Do This

They buy a villa in Benissa or Moraira, calculate the “cap rate” with a cap rate villas Benissa pulled from a portal, set a price per night copied from the best-rated neighbour, suffer low occupancy outside of summer, pay commissions, and end up with poor real estate cash flow. Result: stress and evaporated profitability.

Those Who Win Do This

They buy based on verifiable demand (not based on photos), model occupancy curves by week, distinguish between tourist rental and mid-term (30–90 days) in the low season, pre-calculate total costs and conservative taxation, demand a feasible license before offering, and rely on professional management with metrics. Magic? No. Discipline.

Markus' Case: From 7% on Instagram to a Clean 4.4% Without Tachycardia

Markus, 48, Zurich. Came to Benissa with the idea of “buy-to-let.” Budget: €650,000. Found a villa with partial sea views near La Fustera. Quick Excel: 45 weeks × €300/night = €94,500 per year. “7% net for sure,” someone said at a dinner party.

What Went Wrong

  • Ignored Closing Costs: notary, registry, ITP/VAT, consultancy: +11% approx. Real investment: ~€721,500.
  • Inflated Occupancy: reality of the first year: 28 weeks occupied, average €260/night = €50,960 billed.
  • Operating Costs: management 22% (~€11,211), cleaning and laundry (~€3,800), utilities (~€4,200), IBI+garbage (~€1,200), community (~€1,100), insurance (~€600), pool/garden (~€2,400), unforeseen maintenance (~€2,000), replacements (€1,000), channel commissions (~12% = €6,115). Total estimated direct costs: ~€33,626.

Profit before tax: ~€17,334 → net return on total investment: ~2.4%. After tax (depending on residence), ~1.9–2.2%. It hurts, yes.

What Changed with Method

We repositioned with a local manager in Moraira: editorial-level photography, dynamic pricing, minimum stay of 7 nights at peak, and blocks on “bleeding” weekends. In winter, we switched to mid-term (60–90 days) for European nomads and retirees: €2,200–€2,400/month plus expenses. We adjusted services to avoid triggering VAT/hotel-type services.

  • Year 2 Income: ~€68,000 (35 equivalent weeks + 3 mid-term months).
  • Direct Costs: rise moderately (~€36,000) due to higher occupancy and replacements.
  • Profit before tax: ~€32,000 → ~4.4% net on €721,500. With tax, ~3.5–3.8% depending on the case.

7% net? No. Solid and without shocks? Yes. And the asset, well-cared for and with better reviews, is worth more in the market's eyes. All this in North Costa Blanca, not in a textbook "perfect market."

The Mental Shift You Need (Before Opening Excel)

What if the problem wasn't "occupancy," but your net margin per night? What if you earned more by renting 30 well-paid weeks than 45 given away? What if the right asset is the one that allows a simple license and management, not the one that looks best on Instagram?

Stop buying houses. Buy demand. Buy ease of management. Buy viable permits. Buy cap rate adjusted to the operational truth of Benissa, Calpe, Moraira, and Benitachell.

Your Microplan for Investing Without Self-Deception

1) Market and Demand, Not Desires

  • Season Map: strong, medium, and low weeks by zone (Benissa coast ≠ interior; Moraira ≠ Calpe). Ask for historical data, not promises.
  • Product That Sells: parking, A/C in all bedrooms, stable Wi-Fi, real shade on the terrace, maintainable pool. The “details” make or break the rate.

2) License and Compliance (Before Offering)

  • Urban Compatibility: request a report from the town hall (Benissa, Teulada-Moraira, Calpe, Benitachell).
  • Registration as Tourist Housing: autonomous community registry and technical requirements. Verify community of owners' ordinances if applicable.
  • Fees and Regulations: confirm with a local advisor. Regulations are moving, and 2025 won't be more lenient.

3) Numbers with a Helmet On

  • Closing Costs: 10–13% on price. Always include it in the calculating real estate ROI Spain.
  • Fixed Cost Template: IBI, garbage, community, insurance, internet, pool/garden, minor repairs.
  • Management/Cleaning: if you don't have a manager, calculate your time at market price (seriously).
  • Scenarios: conservative (25–30 weeks), base, and optimistic. If it only works in the optimistic scenario, it doesn't work.

4) Income Strategy

  • Smart Mix: tourist in peak + mid-term in low season to reduce turnover and cleaning costs.
  • Dynamic Pricing: weekly rates, minimum stays, legal and clear extra person supplements.
  • Channels: don't rely on just one. Own website with a booking engine adds conversion and lowers commissions.

5) Taxation and Financing

  • Non-Resident: rate and deductions change depending on EU/EEA. Plan it with an advisor.
  • Mortgage: interest, commissions, and amortization affect your real estate cash flow. Model with a stress test at +200 bps.

6) Local Network and Control

  • Winning Team: rental manager, maintenance, cleaning, pool guy, trusted lawyer, and notary.
  • Quarterly KPIs: weekly occupancy, net average rate, cost per booking, NPS/ratings. Decide with data.

Do you want help without the hype? At Benimo-Villas, we work on exactly this: we validate the license, cross-reference demand by micro-zone, and provide you with real operational numbers for investing in villas in Benissa or buying to let in Moraira with your feet on the ground.

What Changes When You Stop Fantasizing About 7%

You won't "print money," but better things happen:

  • Your calendar stops being a roller coaster: strong weeks full with margin, low season covered with mid-term.
  • The management team stops putting out fires and starts optimizing rate and cost.
  • Your bank account and your Excel finally talk to each other. End of self-deception.
  • You sleep better: fewer suicidal check-ins, fewer calls at 11:00 PM because of a faulty water heater.
  • Your asset revalues because it has reviews, process, and permits in order.

This is not about gathering 200 leads or having the “prettiest” house. It’s about replicable business in the North Costa Blanca. The rest is noise.

Your Next Move (If You Really Want Profitability)

Buy less smoke and more reality. If you are a foreigner and you get lost between LAU, licenses, IBI, consultancy, and "commissions that appear," it's not that you're slow: you lack a local team with skin in the game.
