Budgeting Beyond Purchase: Estimating the Yearly Running Costs of a Foreign Property
Introduction
Buying a holiday home or an investment property abroad is an exciting prospect for many Irish expats and investors. Yet the excitement often ends once the purchase price is settled. The real challenge begins with the ongoing yearly costs that can quickly erode any projected rental yield or holiday‑home budget if they are not properly estimated.
This guide walks you through the main categories of annual out‑goings for foreign property owners, provides up‑to‑date figures for popular destinations (Spain, Portugal, France, Italy), and offers practical tools to keep your budgeting on track. By the end you’ll be able to build a realistic cash‑flow model that protects your investment and helps you enjoy your overseas retreat without unpleasant surprises.
1. Core Annual Expenses You Can’t Ignore
| Expense | What It Covers | Typical Range (€/yr) | Key Notes for Irish Buyers |
|---|---|---|---|
| Municipal Property Tax (IBI, IMI, Taxe foncière, IMU) | Local council levy based on cadastral value | 0.4 %–1.1 % of cadastral value (Spain/Portugal) – ≈ €300‑€1 200 for a €150 k villa | Always payable whether the property is rented or vacant. Non‑residents may need a fiscal representative. |
| Non‑Resident Income Tax (IRNR, IRS, Impôt sur le revenu) | Tax on deemed or actual rental income | 19 % (Spain) – 28 % (France) – 28 % (Italy) on net rental profit | Even if you don’t rent, many jurisdictions tax a “deemed rent” (≈ 1 % of cadastral value). |
| Home Insurance | Building & contents cover, flood, earthquake where relevant | €150‑€500 for a 2‑bed flat; €400‑€1 200 for a villa | Look for policies that cover both permanent and occasional occupation. |
| Utilities (electricity, water, gas, internet) | Ongoing consumption & standing charges | €800‑€1 500 (depending on usage and season) | Some utilities can be placed on a “stand‑by” tariff during off‑season to lower costs. |
| Community/Condominium Fees | Maintenance of shared areas, security, swimming pool, garden | €50‑€300 per month | Fees often rise annually; ask for the last three years of statements. |
| Routine Maintenance & Repairs | Annual upkeep, garden care, HVAC servicing | 1 %–2 % of property value | Budget a reserve fund; larger homes may need more extensive landscaping. |
| Property Management Fees (if rented) | Letting agency, tenant screening, rent collection | 10 %–15 % of gross rent | Some agencies also handle maintenance coordination – a useful all‑in‑one service. |
| Legal & Accounting | Tax filing, representation with local authorities | €200‑€600 per year | Non‑resident owners often require a fiscal representative for IRNR filings. |
| Vacancy & Miscellaneous | Unoccupied periods, unexpected repairs, council levies | 5 %–10 % of projected rental income | A safety net to avoid cash‑flow gaps. |
Tip: Multiply the property’s cadastral value by the local tax rate to obtain a quick IBI/IMI estimate. For a €200 000 Spanish villa with a cadastral value of €70 000 and a 0.75 % IBI rate, the yearly tax is €525.

3. Building a Practical Cash‑Flow Model
3.1 Step‑by‑Step Spreadsheet Layout
| Row | Description | Formula (example) |
|---|---|---|
| 1 | Market Purchase Price | Input (e.g., €250 000) |
| 2 | Cadastral Value | Usually 30‑60 % of market – input (e.g., €80 000) |
| 3 | Municipal Tax (IBI/IMI/Taxe foncière) | Cadastral Value × Tax Rate |
| 4 | Non‑Resident Income Tax | If rented: (Rental Income – Expenses) × Tax RateIf vacant: Cadastral Value × Deemed Rate |
| 5 | Insurance | Fixed annual premium (input) |
| 6 | Utilities | Average monthly × 12 |
| 7 | Community / Condominium Fees | Average monthly × 12 |
| 8 | Maintenance Reserve | Market Price × Maintenance % |
| 9 | Management Fees | Gross Rental Income × Management % |
| 10 | Legal & Accounting | Fixed annual cost (input) |
| 11 | Vacancy Buffer | Projected Rental Income × Vacancy % |
| 12 | Total Annual Out‑goings | SUM(3:11) |
| 13 | Net Cash Flow | Rental Income – Total Out‑goings |
Pro tip for Irish investors: Convert all figures to € using the current exchange rate (≈ 1 £ = 1.17 € as of Oct 2025) and factor in a currency‑fluctuation buffer of 2‑3 % if you receive rental income in the local currency.
3.2 Scenario Planning
- Best‑Case: Property fully let 12 months, low maintenance, no major repairs.
- Base‑Case: 80 % occupancy, 1 % of market value set aside for repairs.
- Worst‑Case: 50 % occupancy, unexpected roof repair (€5 000), insurance premium rise.
Running each scenario through the spreadsheet highlights the break‑even occupancy rate. For many Mediterranean villas, the break‑even point sits around 60‑70 % occupancy when the maintenance reserve is 1 % of market value.
4. Hidden Costs That Often Surprise Buyers
| Hidden Cost | Why It Matters | How to Manage |
|---|---|---|
| Currency Conversion Fees | Rental income or mortgage repayments may be received in euros, GBP, or USD. Fees can eat 0.5 %‑2 % per transaction. | Use a multi‑currency account (e.g., Wise, Revolut) and negotiate low‑cost transfers. |
| Capital Gains Tax on Sale (Plusvalía, CGT) | When you sell, local municipalities levy a tax on land value increase. Rates vary widely. | Keep records of improvements; some regions offer exemptions for primary residences. |
| Tourist Licence & Short‑Let Tax | In Spain and Portugal, short‑term rentals require a licence and a municipal “tourist tax” per night. | Verify licence requirements before listing; include the tax in your nightly rate. |
| Water Scarcity Surcharges (especially in southern Spain) | Seasonal droughts can trigger extra water usage fees. | Install water‑saving devices and monitor consumption. |
| Home‑owner Association (HOA) Special Assessments | Unexpected major works (e.g., pool resurfacing) may be charged as a lump sum. | Ask the HOA for the last three years of special assessments; budget a contingency fund. |
5. Practical Tips for Irish Expats
- Engage a Local Fiscal Representative – Required for IRNR filings in Spain and Portugal; they receive official letters and can act on your behalf.
- Set Up Direct Debit for Municipal Taxes – Many Spanish towns offer a 5 % discount for auto‑debit; similar incentives exist in Portugal.
- Use a Dedicated Property Management Company – They handle tenant vetting, rent collection, and can arrange local maintenance, reducing the risk of missed payments.
- Maintain a “Reserve Account” – Open a euro‑denominated savings account (e.g., in a Spanish bank) and deposit 1 %–2 % of the property value each year.
- Annual Review of Insurance – Ensure coverage includes natural disasters common to the region (earthquakes in Italy, floods in Portugal).
- Leverage Irish Tax Relief – Rental income from abroad must be declared in Ireland; however, you may claim credit for foreign tax paid under the double‑tax treaty.

| Property management (12 % of €12 000 rent) | €1 440 | Includes tenant search |
| Legal & accounting | €300 | Annual filing |
| Vacancy buffer (10 % of projected rent) | €1 200 | Safety net |
| Total Annual Out‑goings | €12 360 | ≈ 4.1 % of purchase price |
