What Your Property Costs You When Nobody Is Staying

The Metre Is Running

An empty property is not a dormant asset. It is a system with fixed costs that run regardless of occupancy. Condominium fees are charged monthly. Property tax is assessed annually. Utility meters tick even when no one turns on a light. Insurance premiums do not pause. Equipment degrades whether it is used or not.

Most property owners in the Algarve and Andalusia understand this intuitively. Few have calculated the actual number. When you add every category — from the condominium quota to the opportunity cost of equity sitting in walls — the total is higher than most people expect.

This article documents what a typical T1 or T2 apartment costs its owner every year it sits empty, using verified 2026 data from Portugal and Spain.

Fixed Charges: The Costs That Never Sleep

Condominium fees are the largest recurring fixed cost for most apartment owners. In the Algarve, a basic building without a pool or lift charges €50-80 per month. Mid-range buildings with a pool and common garden charge €80-150. Resort-style condominiums with pools, gyms, and extensive grounds reach €150-250 per month. In Andalusia, standard urbanizacion fees for a T1 or T2 run €40-150 per month. Under Portuguese law (DL 268/94, Art. 4), each owner must contribute a minimum of 10% of their share of ordinary condominium expenses to a common reserve fund (fundo de reserva) — many condominiums set it higher — a requirement that owners often overlook until a special assessment arrives.

Property tax (IMI/IBI) varies by municipality and is assessed on the property's tax value, not its market value. In Lagos, the IMI rate is 0.30% — the legal minimum. In Portimao, the rate is 0.37-0.38% depending on source — verify against the Portal das Financas or the municipal tax decision for the current year. A T1+1 in Portimao with a VPT (Valor Patrimonial Tributario) of €100,000 pays €370-380 per year. A T2 in Lagos with a VPT of €150,000 pays €450 per year. In Ayamonte, the IBI rate is reported at approximately 0.775-0.79% (sources vary — verify against the Ayamonte ordenanza fiscal or the Agencia Provincial Tributaria de Huelva), but the valor catastral — last reviewed in 1996 — is significantly lower than market value, so the effective annual burden may be comparable to a lower-rate municipality with a more recent catastral revision.

A 2026 update worth noting: the Portuguese government raised the benchmark construction cost to €570 per square metre, a 7% increase. Reporting on automatic valuation updates suggests IMI bills could rise by up to 4.5% for properties affected by the next triennial VPT reassessment, though the actual impact varies by property.

Insurance for an Alojamento Local property in Portugal requires mandatory civil liability coverage. ALEP membership includes one AL public liability policy, with additional coverage starting from €39 per year. On the open market, premiums range from €52 to €441 depending on capacity and capital insured. A comprehensive multirriscos policy adds €100-500 per year depending on coverage. The recommended total for a T1 or T2 is €150-350 per year. Since March 2025, insurance data must be submitted on Gov.pt and is publicly visible on the RNAL registry. Municipalities now have the authority to cancel AL registrations for properties lacking proof of insurance.

Standby Utilities: Paying for Nothing

The most psychologically frustrating holding cost is utilities. The property is empty. Nobody is showering. Nobody is watching television. Yet the bills arrive.

Electricity accounts for the largest share. A property equipped for air conditioning needs a potencia contratada (contracted power) of 5.75 to 6.9 kVA. The fixed charge for this capacity alone is €15-20 per month. A running fridge and router add €10-15 per month in consumption. Total: €25-35 per month, even with no guest. One practical measure: reducing the potencia contratada when the property is empty saves approximately €36 per year per echelon dropped.

Water in the Algarve costs 46% more than the national Portuguese average. Fixed meter fees, saneamento (sewage), and residuos (waste) charges total €8-15 per month with zero consumption. In Portugal, the garbage tax is included in this water bill. In Spain, basura is a separate municipal tax costing €60-120 per year.

Internet runs €10-45 per month for standalone fibre. DIGI, which launched in Portugal in late 2024, offers 1 Gbps from €10 per month — though Algarve coverage is currently limited to Lagos, Portimao, and Albufeira. MEO, NOS, and Vodafone standalone fibre (without TV or phone bundles) typically costs €35-45 per month. A connected property is necessary for smart locks, security cameras, and guest communications. Disconnecting between stays is rarely practical.

Total standby utilities: €60-85 per month. That is €720-1,020 per year for the privilege of keeping the lights ready to turn on.

Maintenance, Depreciation, and the Things That Wear Out Anyway

Preventive maintenance is not optional for a property that must be guest-ready on short notice. Servicing two air conditioning units costs €200-300 per year. A basic plumbing inspection runs €50-100. A painting reserve — budgeting for a full repaint costing €600-1,200 every three to five years — requires setting aside €150-250 annually. A general contingency fund for unexpected repairs adds €200-400. Total preventive maintenance: €600-1,050 per year depending on property size.

Depreciation reserves account for the replacement cycle of furnishings and appliances. Mattresses last three to five years. Linens last one to two years. Kitchen appliances last five to twelve years. For a T1, the annual depreciation reserve is €500-800. For a T2, it is €700-1,100. These are not expenses that appear on any bill. They are costs that materialise suddenly when a washing machine fails or a sofa becomes unacceptable.

Vacant property cleaning is distinct from turnover cleaning. A bi-annual deep clean and airing — necessary to prevent dust accumulation, mould, and stale odours — costs €100-150 per year. This is a holding cost, not an operational one.

Pest control is particularly relevant in the Algarve, where ground-floor apartments in coastal areas face humidity-related pest pressure. Quarterly treatments cost €80-150 per year.

Bookkeeping for an active AL or VUT licence requires periodic VAT and income declarations. Professional accounting services cost €150-300 per year in Portugal and a similar amount in Spain.

The Full Cost Table

The following table summarises the annual holding cost of a vacant T1 or T2 apartment in the Algarve or Andalusia. All figures are in euros and reflect 2026 data.

Monthly equivalent: €517-694 (T1) / €556-800 (T2).

* The 2% net figure is a blended estimate between Certificados de Aforro (1.45% net) and best bank deposits (up to 2.16% net). It is not a specific product rate.

Spain-specific additions: Properties in Andalusia should add imputed income tax (Modelo 210, filed by December 31 of the following year). For properties with a catastral revision older than 10 years — such as Ayamonte (last revised 1996) — the rate is 2% of the valor catastral, multiplied by 19% for EU residents. On an €80,000 catastral value, that is approximately €304/year. For properties with a more recent revision, the rate is 1.1%, yielding approximately €167/year. Add also basura tax (€60-120/year) and a fiscal representative fee for non-residents (€200-400/year).

Tax note: Many of these holding costs — condominium fees, IMI, insurance, maintenance — are legally deductible against rental income, depending on the owner's tax regime (e.g., Category B or F in Portugal). This is one reason the bookkeeping line item matters: proper accounting ensures these deductions are captured.

Scope note: This article covers holding costs only. It does not cover rental income taxation, capital gains on sale, property management fees, or mortgage servicing.

Opportunity Cost: The Money Your Walls Are Holding

The table above includes a line most property cost analyses omit: opportunity cost. This is the return your capital could generate if it were not locked in the property.

Portuguese Certificados de Aforro (Series F) currently yield 2.012% gross, which nets 1.45% after the 28% IRS withholding tax. The best bank deposits offer up to 3.00% gross. Portugal's 10-year government bond yields approximately 3%. These instruments carry different risk profiles — comparing a savings product to a bond conflates duration risk — but they bracket the realistic range of low-risk returns available to a Portuguese investor.

On €150,000 of tied-up equity, the opportunity cost ranges from approximately €2,171 per year (Certificados de Aforro net) to €3,240 per year (best deposit net). The table uses a blended 2% net estimate — between the Certificados floor and the best-deposit ceiling — yielding €3,000 per year. This is not a cash outflow. It is a real economic cost that compounds annually.

A property that costs €5,000 per year in fixed expenses and reserves, plus €3,000 in foregone returns, has a total economic cost of €8,000. That is the revenue threshold the property must exceed before it generates any real return.

The LusiberiaStays Approach

At LusiberiaStays, holding costs are not an afterthought. They are the baseline against which every operational decision is measured. Each property in the portfolio — Blue Heaven in Lagos, Alvorada in Alvor, Sun Villa in Costa Esuri — has a documented annual holding cost that is reviewed quarterly.

This cost-aware approach shapes several operational practices:

• Potencia contratada management. Contracted electricity power is adjusted seasonally based on expected occupancy, reducing fixed charges during low-demand periods.
• Preventive maintenance scheduling. AC servicing, plumbing checks, and deep cleaning are scheduled during vacancy windows, converting idle time into maintenance time rather than treating both as separate costs.
• Insurance consolidation. Civil liability and multirriscos policies are reviewed annually against ALEP group rates and open-market alternatives to avoid overpaying for mandatory coverage.
• Depreciation tracking. Every furnishing and appliance has an expected replacement date and a monthly reserve allocation. Replacements are planned, not reactive.
• Transparent cost reporting. Property owners receive a full holding cost breakdown alongside revenue reports. The goal is not to minimise a single line item but to ensure total economic cost is understood and accounted for in pricing and occupancy targets.

A property that earns €12,000 in gross rental revenue but costs €6,500 to hold is not a €12,000 asset. It is a €5,500 asset. The difference between operators who understand this and those who do not is the difference between sustainable management and gradual capital erosion.

Regulatory Notes: Portugal and Spain Compared

AL licensing in Portugal is now indefinite. The five-year renewal requirement introduced under "Mais Habitacao" restrictions has been reversed. Registration is free. However, fines for non-compliance range from €2,500 to €4,000 for individuals. The administrative burden is real but contained.

VUT licensing in Andalusia is also free to register, but the practical requirements have expanded since July 2025. Properties must now register with the National Registry (NRA) and obtain a digital certificate. Depending on the municipality and the building's comunidad de propietarios, a community approval certificate may also be required. In some cases, acquiring the necessary technical compliance documentation involves upfront professional fees. These are not recurring holding costs, but they represent a meaningful administrative barrier for owners who have not yet formalised their licence.

Imputed income tax in Spain is a cost unique to the Spanish system. Non-resident owners of vacant properties must file Modelo 210 annually (by December 31 of the following year). The base rate depends on when the property's catastral value was last revised: 1.1% if revised within the last 10 years, or 2% if older. This is multiplied by 19% for EU residents or 24% for non-EU residents. For a property in Ayamonte (last catastral revision 1996) with a valor catastral of €80,000, the calculation is: €80,000 x 2% x 19% = approximately €304 per year for an EU resident. A property with a more recent revision would owe €80,000 x 1.1% x 19% = approximately €167. This obligation does not exist in Portugal for empty properties.

AIMI (Adicional ao IMI) in Portugal applies only to owners whose total VPT across all properties exceeds €600,000 (single) or €1,200,000 (married filing jointly). The rate is 0.7% on the portion between €600,000 and €1,000,000. For most individual property owners, AIMI does not apply. For portfolio investors, it is a material consideration. Separately, some Portuguese municipalities are beginning to apply discretionary IMI surcharges on properties used for local accommodation or left vacant — a trend worth monitoring even if not yet widespread.

Fiscal representation is required for non-resident property owners in both countries. In Portugal, a fiscal representative costs €150-300 per year. In Spain, the cost is €200-400 per year, typically bundled with Modelo 210 filing. This is a non-negotiable cost for any non-resident owner and one that is frequently omitted from property cost projections.
