Renovate before selling? It depends on the renovation: some works the buyer pays back with interest, others recover only part of every euro invested. The golden rule: the buyer pays for what they see and what saves them trouble, not for what you like.
"Should I renovate before selling?" is one of the questions owners ask us most. The short answer: it depends on the renovation. Some works the buyer pays back with interest; in others, every euro invested is only partly recovered — or directly scares buyers away. The golden rule is one: the buyer pays for what they see and what saves them trouble, not for what you like.
The 5 that do raise the price
1. An updated kitchen and bathrooms. They are the two rooms that sell a flat — and the works the average buyer dreads most, because they mean weeks of not living in the house. A functional, current kitchen and a renovated bathroom transform the perception of the whole flat. You don't even need "magazine" level: correct materials, neutral colours and everything working.
2. Renewed installations (the invisible renovation that gives peace of mind). Up-to-date electrics and trouble-free plumbing don't shine in photos, but they pass the informed buyer's inspection — and their bank's appraiser. A compliant electrical certificate and a modern boiler remove the two objections that kill the most offers on older flats.
3. Energy efficiency: windows and insulation. More and more buyers check the energy certificate's rating, because they have understood it means money every month. Replacing old windows with double glazing is among the investments with the best return: it shows, it is felt (noise and cold) and it improves the rating.
4. Paint, light and floors: the honest facelift. Painting in light colours, updating the lighting and renewing a worn floor (or sanding the parquet) is the cheapest renovation per euro of impact. It is also the difference between listing photos that attract viewings and ones that drive them away.
5. Adaptations that widen your market. Anything that makes the flat suitable for more buyer types adds up: a shower tray instead of an old bathtub opens the flat to older buyers; solving the building's accessibility, when it depends on you, too. More possible demand = better price.
The 3 where you lose money
1. The full renovation to your taste just before selling. "Leaving it perfect" sounds logical, but taste is personal: the porcelain tile you love may be exactly what the buyer planned to remove. In large renovations you rarely recover 100% of the investment — and you often compete against unrenovated flats whose buyers wanted precisely to renovate to their own taste. Exception: flats so deteriorated that without works they cannot be financed.
2. Luxury finishes in a mid-price area. Every area has a price ceiling, and no renovation breaks it. Installing a high-end kitchen and home automation in a flat whose market ceiling is set by its location is giving the difference away: buyers in that area will not pay it.
3. Works without a licence or without being legalised. Closing a terrace, knocking a wall through "without papers", converting commercial premises... Anything not legalised becomes a problem at the sale: the appraisal detects it, the bank blocks the buyer's mortgage and the deal falls through or is renegotiated downwards. If you did unlegalised works, regularise them before selling, not during.
How to decide in your case: the maths before the works
Before spending a euro, do (or ask us for) this calculation: what your flat is worth today as is, what it would be worth with the specific renovation you have in mind, and what that renovation costs all-in. Only if the second number clearly exceeds the sum of the other two does the work make economic sense. And sometimes the answer is in between: don't renovate, but do invest a few hundred euros in the tune-up (paint, small repairs, deep cleaning and good presentation) — the famous home staging, which almost always wins on cost-versus-impact.
At Signem we do this maths with real sales data from Manresa and the Bages: we tell you what the market would pay for your flat today, what it would pay renovated, and you decide. It is part of our usual marketing plan, together with professional photography and home staging.
