Buy a renovated flat or one to renovate: which suits living in it

Which suits living in it: a renovated flat or one to renovate?

A flat to renovate wins if you want your own layout and known services; a renovated one wins on time if you can check its hidden parts. The riskiest option is in the middle: a flat with a cosmetic refresh, where new finishes cover old problems.

The choice rests on three things: how much time and how many decisions you are willing to invest, how well the work already done can be checked, and whether the layout as it stands suits you. For living in, the benefit is measured not in yield but in what you get on moving-in day: quiet, flat walls, reliable power and water, light you find comfortable.

Below we compare both routes by criteria, then list what to check in someone else's renovation, how to learn about hidden works before buying, which is faster, and how to tell whether the layout needs changing.

How do the two routes differ in control, time and budget?

To renovate: you control layout, hidden works and materials, but pay in time and in the risk of opening up. Renovated: you get the result at once, but with someone else's decisions and unverified pipes.

Control of layout. To renovate: total, down to the position of bathrooms and ceiling heights; renovated: limited, every change breaks a fresh finish and doubles the cost. Quality of hidden work. To renovate: you see walls and risers open and decide what to replace; renovated: you trust documents and photos, because inside everything is already closed. Time. To renovate: design, licence and works, months rather than weeks, and the exact duration comes from the contractor after a visit; renovated: weeks until you move in, plus touch-ups. Budget. To renovate: you know the structure of spending and can choose the level; renovated: the price includes someone else's choices, which you pay for in the purchase price even if you do not want them.

For an owner who does not live in Spain, time often matters more. But the speed of a renovated flat can turn into a surprise if hidden defects appear. That is why an inspection by a technical professional before buying pays off in both scenarios.

How do you check the quality of a renovation in a flat sold after a cosmetic refresh?

Start with what cannot be painted over: the board, the pipes, the noise and the documents. A cosmetic refresh easily hides what is visible but poorly hides what can be touched and heard.

Board. Open it: are there residual-current devices, are the circuits labelled, are there twisted joints or home-made additions, how many free modules. An old fuse board next to new tile says the services were not touched. Sockets: earth in each, check with a tester. Water: run several taps at once, look at pressure and the colour of the water in the first seconds, find the risers and see whether they are galvanised. Damp: corners by windows, the wall behind the bathroom, the bottom of cupboards; a moisture meter costs little. Noise: ask to stand in silence for a while, listen to the stairs, the lift, the neighbours; if they say the floor is floating, it should be. Windows: gaps, draughts, glass level. Ceilings: a false ceiling can hide beams and ducts; ask what is above it.

Documents. Ask for the cédula de habitabilidad, the energy certificate, the electrical bulletin (CIE), the gas certificate, the building's ITE report, details of the licence for the previous works, and community minutes on planned costs. If the seller answers «later», note it.

What can you learn about hidden works before buying?

A lot, if you ask for documents and photos rather than words. Hidden works cannot be seen, but they leave a paper and photographic trail.

Ask the seller for: the contract and quote of the previous renovation, the contractor's name, photos during the process (especially before walls and screeds were closed), invoices for materials and equipment, licence documents if there was one, and electrical and gas certificates. If the renovation was done for the seller's own use rather than for sale, there is usually more of a trail, and that is a good sign. If the flat was bought, quickly finished and put on the market, there is almost no trail and closed-up things remain a mystery.

Second step: an inspection by an independent technical professional. In half a day they check the board, risers, damp and levels, test likely trouble spots with a thermal camera and moisture meter, and write notes. You cannot open up someone else's flat before buying, so the aim of the inspection is not an exact diagnosis but a list of questions for the seller and an argument for negotiating. If more questions than answers remain after the inspection, consider a flat to renovate in the same area.

Which is faster: renovating to your taste or adapting a finished flat?

Adapting a finished flat is faster when you change finishes, lighting, paint and furniture; renovating to your taste is faster than redoing someone else's renovation. Changing the layout of a finished flat wastes recent work and usually costs more and takes longer.

For cosmetic changes the picture is simple: painting, changing lights and handles, curtains and furniture take weeks. But if you want to move a bathroom, join kitchen and living room, or change the cooling system, what was just built has to be opened up and the demolition paid for twice: the previous work you break and your own. A flat bought to renovate avoids those costs but needs a design, a licence and works, that is months rather than weeks.

So for those who want to move in quickly the sensible route is to choose a finished flat with a layout that will not need changing and limit adaptation to furniture and lighting. Whoever wants an exact layout should allow for renovation time from the start. The exact duration comes from the contractor after a visit and measurements.

How do you judge whether the layout needs changing?

Assess four things: load-bearing elements, the position of wet areas, height and light. They determine what is possible and what it costs before design is even discussed.

Load-bearing walls and slabs. In old Eixample buildings the walls are brick and load-bearing, and the floors rest on beams; without a technical professional's report a wall is not touched. Wet areas: drain stacks are fixed, and moving a kitchen or bathroom to the other side of the flat needs falls, which means height in the floor or the ceiling. Height: in the Eixample ceilings are often enough for a false ceiling with ventilation ducts and lighting; in lower flats you have to choose. Light and windows: a dark middle of the flat is solved with openings and glass partitions, but openings in load-bearing walls need a design.

Alongside this is the question of what you want to keep: hydraulic tile, plaster-moulded ceilings, original doors. Sometimes the best layout change is none, and careful restoration is what is needed. A visit, measurements and a survey of the property let you answer these questions with figures rather than feelings.
