Not all renovations made to a property or commercial space have the same effect on its market value. Before approving a renovation in a meeting or recommending an investment to an owner, it's important to separate narrative from data: increasing property value with renovations is possible, but the return varies greatly depending on the type of intervention, the city, and the initial state of the property. In this article, we review what the latest industry analyses say about prices, return on investment, and the bathroom and kitchen renovations that most interest communities and owners.
Does Renovating Really Increase Value? What the Data Says
The market confirms that it's worth maintaining the condition of a property before selling or renting it. A renovated property sells in Spain for between 8% and 15% more than an equivalent without renovations, and takes 40% less time to find a buyer, according to data from the consultancy RESA. Additionally, the average return on a well-planned renovation can range from 70% to 200% depending on the type of intervention, clearly showing that not all renovations are equally profitable.
Size and type also matter. One-bedroom properties increase their value by 29% after renovation, followed by two-bedroom apartments (28%) and three-bedroom apartments (26%), although this relationship changes in more competitive markets: in cities like Barcelona, the improvement from renovating a studio is only 15%, compared to 24% for apartments with four or more bedrooms. In the specific case of buying to renovate and sell, a study by Casavo and Gesvalt places the average appreciation in Madrid at around 35% for complete renovations, and 42% in Barcelona, making the Catalan city one of the markets where investing in renovations is most worthwhile.
Cost of Complete Renovation in Barcelona: How Much Each Range Costs
Before calculating any return, you must start with a realistic budget. According to current industry references, a complete renovation of a 60-70 m² apartment ranges from €55,000 to €80,000 depending on the initial condition and quality, while an 80-100 m² apartment is between €75,000 and €120,000 depending on layout, installations, and level of finishes. Per square meter, a mid-to-high-quality complete renovation ranges from €900 to €1,400/m² including project, licenses, construction, and project management, while premium qualities exceed €1,500-1,800/m². As always, the factors that most impact the final price are the condition of existing installations, structural changes, access to the building for work logistics, and the quality of kitchens and bathrooms. To compare real budgets and avoid surprises, the most practical approach is to request several quotes through ForConnect's directory of verified professionals, which allows you to compare prices and timelines before deciding.
Real ROI by Type of Work: From Painting to Complete Renovation
The most useful data for an administrator or community president is not the cost of the work, but its return. Cosmetic interventions are usually the most profitable in proportion to the investment: painting the property in neutral tones, updating a bathroom without structural work, or changing the lighting are low-cost improvements with a very high recovery rate. Complete kitchen and bathroom renovations, on the other hand, cost more in absolute terms but also raise the final sale price, although their return percentage is usually more moderate than that of a simple tune-up. In complete renovation projects, investing around €7,000 in renovating a complete bathroom can generate an ROI close to 90%, recovering almost the entire investment in the sale price and eliminating one of the most common objections among buyers and tenants.
The lesson for a community bathroom and kitchen renovation is clear: prioritize actions that improve functionality, efficiency, and perception of modernity (faucets, sanitary ware, appliances, lighting) over luxuries that increase the cost without providing proportional return. Very sophisticated renovations like advanced home automation or private pools tend to have a return far below their cost, while functional kitchen and bathroom improvements remain among the safest investments.
Commercial Spaces: Is It Worth Renovating Before Renting or Selling?
In communities with ground-floor commercial spaces, the question is constantly repeated: should we renovate before putting the space on the market? The logic is similar to that of residential properties, but with nuances specific to commercial use. A space with updated installations (electricity, air conditioning, accessibility, facade image) rents or sells faster and at a better price, especially on streets with high commercial turnover. The key is not to overinvest in design finishes that the future tenant will likely change, and to focus the budget on what truly affects use: installations, energy efficiency, and regulatory compliance. For commercial spaces, as with residential properties, comparing several quotes before deciding avoids both under-investing in the renovation and investing in improvements that the market will not pay for.
Keys to Adding Value with Renovation Without Surprises
- Always request more than one detailed budget by items (installations, masonry, kitchen and bathrooms, finishes) before approving a work in a meeting or individually.
- Prioritize installations and efficiency over luxury finishes: they usually have better medium-term returns.
- In bathroom and kitchen renovations, invest in functionality and durability rather than in fleeting aesthetic trends.
- Consider the general condition of the building: a renovated property in a building with a deteriorated facade or common installations appreciates less than in a well-maintained building.
- Calculate the real ROI by subtracting taxes, sales fees, and management expenses before accepting any appreciation estimate.
Renovation trends for 2026 point to increasingly calculated decisions: less work on a whim and more investment oriented towards real return, both in residential and commercial spaces.
