Buying a home to renovate in Madrid: common mistakes
The best time to call an architect is not after buying, but before. Most renovation mistakes are made —or avoided— at the moment of purchase.
Buying a home to renovate in Madrid can be an excellent investment decision, but it is also where the most expensive mistakes are made. Most do not happen during the works, but before: in how the property is chosen and valued. These are the ones we see most often, and how to avoid them.
1. Falling for the flat, not the potential
A good property to renovate is not the one in the best condition, but the one that can end up best: orientation, light, ceiling height, the possibility of reorganising the layout. Sometimes the ugliest home is the best buy. A professional look before signing completely changes the valuation.
2. Underestimating permits and the residents' association
Not every intervention is equally simple. Touching the façade, structure or shared services requires permits and, often, the approval of the residents' association. In buildings with protected elements there are limits. Knowing them before buying avoids buying a problem.
3. Buying without an idea of the project
Signing without knowing whether the home allows what you imagine —opening up the kitchen, gaining a bathroom, creating a dressing room— is betting blind. A preliminary design, even a simple one, confirms what is possible and at what cost.
4. Budgeting without a cushion
In the renovation of old buildings, the unexpected always appears: a beam, a drainpipe, an obsolete installation. A realistic budget includes a margin. Calculating to the limit is a recipe for trouble.
5. Choosing by price per square metre, not final cost
Two flats at the same price per square metre can have very different renovation costs depending on their condition. What matters is the total cost —purchase plus renovation— and the final value of the finished home.
6. Ignoring the state of the building
The home may be immaculate and the building not. A façade pending renovation, a lift due for replacement or an unfavourable building inspection can mean significant levies worth knowing about before signing. Looking at the building, and not just the flat, is part of a prudent purchase.
7. Doing without a single point of responsibility
Coordinating architect, contractor, trades and suppliers on your own is a full-time job and a source of cost overruns. Having a studio that directs the whole process —design, works and interior design— is what prevents decisions from getting lost between hands and the result from drifting away from what you imagined.
The right order
The sequence that works is: view the home with an architect before buying, confirm possibilities and an indicative budget, and only then sign. That is what our express consultation is for: one hour with Mónica that can save you mistakes with many zeros. And if you want the detail of the buying process —NIE, deposit contract, deed, taxes—, we explain it in this step-by-step guide.
