Which Renovations Add Value to a Property Abroad (and Which Just Burn Cash): Remodel Costs by Country

Published on: June 21, 2026

Quick answer: The renovations that reliably pay you back abroad are the universal ones: kitchens, bathrooms, energy efficiency, usable space, and fixing the unglamorous structural basics, all kept disciplined below your local ceiling price. The ones that burn cash are the personal, the luxury, and the over-improved: pools, heavy personalisation, and top-tier finishes in a mid-market building. Spend where the next buyer will value it, not only where you will. Typical mid-range kitchen and bathroom remodel costs range from roughly €3,500 in Turkey to €30,000 in France.

Renovating a home in your own country is hard enough. Doing it in a country where you don't live, in a language you may not speak fluently, for a resale market whose buyers want different things than you do, is a different sport entirely. Get it right and you lift both your day-to-day enjoyment and the price the next buyer will pay. Get it wrong and you can pour €30,000 into changes the next owner rips straight out.

This guide separates the renovations that reliably pay you back from the ones that simply burn cash, with typical remodel costs across six of the most popular markets for international buyers.

The one rule that governs every overseas renovation: the local ceiling price

Before any single decision about kitchens, floors or pools, understand the most important concept in renovation economics: the ceiling price.

Every street, building and town has a price ceiling, the most a buyer will realistically pay for any property there, no matter how beautiful. A modest apartment block on the Costa del Sol might have a ceiling of €300,000. If your apartment is already worth €260,000, you have roughly €40,000 of "headroom" before further spending stops adding value. Spend €80,000 on a designer renovation and you have simply gifted €40,000 to the next buyer.

This matters far more abroad than at home, because international buyers often arrive with budgets and taste calibrated to a more expensive country. A renovation that feels normal in London or Munich can blow straight past the ceiling of a Greek island village or a Portuguese hill town. The discipline is always the same: renovate to the top of your local market, not to the standard of your home country.

Renovations that reliably add value

These are the changes that buyers in almost every market pay for.

Kitchens. The single biggest lever. A tired kitchen is the first thing a buyer mentally deducts money for; a clean, functional, light kitchen is the first thing that makes them imagine living there. You do not need a luxury kitchen, you need one that looks new, works well and matches the property's level. A mid-range refit usually returns most or all of its cost in added value, and dramatically improves saleability.

Bathrooms. Close behind kitchens. Dated, mouldy or poorly laid-out bathrooms scare buyers; modern, well-sealed ones reassure them. In hot-climate markets, a second bathroom or an en-suite can lift a property into a higher bracket, particularly for villas marketed to families or holiday-let investors.

Energy efficiency. This has shifted from "nice to have" to "affects whether you can sell or let at all," especially in the EU. Energy Performance Certificates are now legally required for sales and rentals across the bloc, and poor ratings are starting to carry real consequences. In France, the worst-rated homes (the passoires thermiques, or "thermal sieves") face progressive bans on being rented out. Insulation, double or triple glazing, an efficient heating/cooling system and, where it makes sense, solar all improve the certificate and the price, and cut running costs while you own.

Usable space. Converting a basement, garage, attic or outbuilding into a habitable room, or adding a bedroom within the existing footprint, almost always adds value, because buyers compare on bedroom and bathroom count first. Adding floor area legally (with permits) is one of the most reliable ways to move into a higher price bracket. Just be sure the work is declared and registered; undeclared extensions are a classic resale problem abroad.

Fixing the unglamorous problems. A sound roof, dry walls, safe wiring and working plumbing add no "wow" to a viewing, but their absence is what collapses a sale or triggers a price chip after a survey. Money spent removing damp, replacing a failing roof or rewiring an old house protects your sale price even though buyers never coo over it. (These big, often non-optional repairs deserve their own treatment, see our separate guide on roofs, structure and rewiring.)

Curb appeal. A repainted façade, a tidy entrance, fresh shutters, a clean terrace, cheap relative to their impact on first impressions and asking price. Outdoor living space is heavily weighted in Mediterranean and Gulf markets.

Renovations that rarely return their cost

These can be wonderful to own, just don't expect the spend back when you sell.

Swimming pools. A pool can make a hot-climate villa easier to sell and let, but it almost never returns its full build cost in resale value, and it adds ongoing expense and maintenance. Treat it as a lifestyle and rentability decision, not an investment. (We break the real numbers down in our dedicated pool cost guide.)

Heavy personalisation. Bold colour schemes, unusual layouts, a wine cellar, a home cinema, a sauna, these reflect your taste, and the next buyer is statistically unlikely to share it. Niche luxury features rarely add what they cost.

Over-improving past the ceiling. Top-tier marble, imported designer fittings and architect-grade finishes in a mid-market building are money you will not recover.

Knocking rooms together. In markets that price on bedroom count (most of them), turning three small bedrooms into one large suite can reduce your value even if it looks better.

Extreme landscaping. Mature gardens are lovely, but elaborate landscaping is expensive to install, expensive to maintain (a deterrent to some buyers), and rarely valued at cost.

Typical remodel costs by country

Indicative 2025–2026 ranges for a standard refit at mid-market quality. Costs vary widely with size, finish level, structural surprises and region (capitals and prime coasts run higher). Always get at least three local quotes.

Labour is the swing factor. France and Italy sit at the higher end on labour; Turkey is markedly cheaper but quality and project management vary more, so vetting your builder matters even more (see our hiring a builder guide).

Country notes for buyers

France. Older stone houses are characterful but can be cold and energy-hungry. With the thermal-sieve rental rules tightening, energy renovation is no longer optional for many letting investors, it is the difference between a property you can rent and one you cannot. Budget for insulation and an efficient heating/cooling system, not just cosmetics.

Spain. On the costas, the split between coastal apartments and inland villas is sharp. For apartments, kitchen, bathroom and air conditioning dominate the value equation. For villas, outdoor space, a pool (for saleability) and a second bathroom matter most. Note that energy certificates are mandatory and that any extension must be properly registered with the catastro and Land Registry.

Italy. Cheap-house schemes generate headlines, but the renovation reality is often a multi-year project with significant cost and bureaucracy. Italy has historically offered generous renovation tax incentives (the Superbonus and related bonus schemes), though the terms have repeatedly changed, check what is currently available before you budget, because the right incentive can transform the economics.

Portugal. Strong demand and a competent trades market, with renovation costs generally below France and Italy. Energy upgrades and modern bathrooms add well in the lettings market.

Greece. Island logistics raise costs, shipping materials and labour to a small island adds a premium that mainland projects don't carry. Factor it in before assuming "cheap Greek labour."

Turkey. The lowest headline costs of the group, with the trade-off that quality, contracts and remote project management are less standardised. The savings are real, but so is the need for a trusted builder and clear written agreements.

Renovating from another country

The economics above assume the work is actually delivered as specified, which, when you're not there to watch, is the hard part. Get fixed-price written quotes, pay in stages tied to completed milestones, never pay the full amount up front, and consider a local project manager or architect to supervise on your behalf. We cover the full remote-hiring playbook, including how to avoid being overcharged, in our companion guide on big-ticket repairs and choosing a builder abroad.

Frequently asked questions

Does a new kitchen add value to a property?
Usually yes, a mid-range kitchen refit is one of the most reliable value-adding renovations, and it strongly improves saleability. A luxury kitchen in a mid-market home, however, rarely returns its full cost.

Is it worth renovating an old house in France?
It can be, but the maths hinges on two things: keeping total spend below the local ceiling price, and prioritising energy efficiency, because the worst-rated homes face growing restrictions on being rented out. Cosmetic-only renovations of a thermally poor house are the riskiest.

How much does a bathroom remodel cost in Spain or Italy?
As a 2025–2026 guide, expect roughly €4,500–€12,000 in Spain and €5,000–€14,000 in Italy for a mid-range refit, with the final figure driven by size, finish and any hidden plumbing or waterproofing problems uncovered along the way.

Will renovating increase my property tax abroad?
It can. Adding registered floor area or significantly increasing a property's rateable value can raise local property taxes, and any extension must usually be declared. Check the local rules before assuming a renovation is tax-neutral.

The renovations that pay you back abroad are the universal ones, kitchens, bathrooms, energy efficiency, usable space and fixing the unglamorous structural basics, kept disciplined below your local ceiling price. The ones that burn cash are the personal, the luxury and the over-improved. Spend where the next buyer will value it, not only where you will, and your overseas renovation strengthens your asset instead of quietly subsidising the person who buys it from you.
