Is it worth renovating before selling?
Does a new bathroom for €15,000 increase the sale price by the same amount? Often, the answer is no. Learn how to achieve the maximum return with targeted investments instead of making costly mistakes.
With access to Google, BORIS, and Deep Research.
Cosmetic repairs (e.g., painting work) often offer the highest return on investment as they significantly enhance the crucial first impression at minimal cost.
Major renovations like new bathrooms or kitchens are risky, as the costs (often €15,000-€25,000) frequently exceed the achievable increase in value, and buyers' tastes are rarely met.
Energy renovations have become a key value driver through the Buildings Energy Act; a better energy efficiency class can increase the sales value by over 15%.
Are you about to sell your property and wondering if you should invest money into a renovation? This decision is crucial, as not every measure pays off. An expensive renovation can lower the sale price if it doesn't match buyers' tastes, while even minor cosmetic repairs can increase value by several percentage points. This article provides you with a data-based foundation for making your decision. We'll show you which investments statistically pay off, where the biggest financial pitfalls lie, and how to conduct a well-founded cost-benefit analysis before you spend a single euro.
For those in a hurry looking for a quick, data-driven answer:
Low Investment, High Impact: Cosmetic repairs like a fresh coat of paint or updating light switches often yield the highest return on investment (ROI) and can significantly enhance the first impression.
Major Projects are Risky: Complete bathroom or kitchen renovations are expensive and rarely appeal to all potential buyers' tastes. The costs often exceed the actual value increase of 5-10%.
Energy Efficiency is Key: Measures to improve energy efficiency ratings (e.g., from G to D) are value-boosting due to the Building Energy Act (GEG) and can increase the sale price by up to 15%.
Consider Buyer Psychology: Unrenovated properties often suffer a price reduction of 10-30% because buyers subconsciously overestimate renovation costs.
Data Beats Gut Feeling: A professional cost-benefit analysis is the only reliable way to avoid bad investments and strategically maximize the sale proceeds.
Every renovation decision must be based on a single question: Is the expected increase in value higher than the costs invested? A renovation is only worthwhile if the answer is a clear yes. Keep in mind that buyers often estimate the costs for necessary repairs to be 20-30% higher than they actually are, leading to disproportionately large price reductions. An investment of €5,000 to address visible defects can thus prevent a price loss of €10,000. A data-driven evaluation, such as the one provided by the Auctoa Renovation Potential Report, protects you from such costly misjudgments. This analysis is the first step in fully realizing your property's potential.
First impressions count – and often they can be significantly improved with less than 2% of the sale price. Minor defects, such as peeling wallpaper or scratched floors, can deter potential buyers and negatively impact price negotiations. Here lies the greatest potential for a high return. Focus your budget on measures that are immediately visible and signal a well-maintained condition. Even a fresh coat of paint in neutral colours can increase the perceived value by 1-3%. The most effective cosmetic measures are:
Fresh paint on walls and ceilings (Cost: approx. €10-15 per m²)
Replacement of outdated light switches and sockets (Cost: approx. €20 each)
Renewal of door and window handles for a modern feel
A thorough, professional cleaning of the entire property
Maintenance of the outdoor area: mowing the lawn, removing weeds, and an inviting entrance area
These small changes shape the overall impression that buyers retain during a viewing. Learn more about how to optimally present your property.
A complete bathroom renovation for €20,000 or a new kitchen for €15,000? Such investments are tempting but highly risky. Buyers' tastes are individual, and an expensive, yet very specific, fit-out can deter up to 50% of potential buyers. A study shows that upgrading features from "standard" to "premium" can increase value by 15-20%, but the costs often outweigh this added value. A rule of thumb is that you only recoup about 50-70% of the costs of a complete kitchen or bathroom renovation in the sale price. Instead of a full renovation, targeted partial modernisations are often the wiser choice:
Replacing the kitchen worktop
Renewing the fittings in the bathroom and kitchen
Installing a modern shower cubicle instead of an old bathtub
Painting old kitchen fronts instead of a complete replacement
This way you significantly improve the appearance without breaking the budget and learn what buyers really want. The decision for or against such projects strongly depends on the target group.
Since the Building Energy Act (Gebäudeenergiegesetz - GEG), energy efficiency is no longer a secondary issue, but a central value driver. A property with energy efficiency class A can achieve an average price of €412 per square metre higher than a comparable property with class C. For a living space of 150 m², this corresponds to a value difference of over €60,000. Therefore, investing in a better energy class is often not just a question of cost, but a strategic necessity. These three measures are often particularly profitable:
Insulation of the top floor ceiling: Costs around €2,000-4,000, and quickly pays off.
Replacement of old windows: An investment of €10,000-20,000, which significantly improves living comfort and energy balance.
Renewal of the heating system: Often legally required and a clear selling point.
These measures are not only good for the environment but also for your bank balance. A targeted analysis shows you which renovations buyers are convinced.
The question of whether renovation prior to selling is worthwhile has no simple answer. It is a complex balance between costs, expected increase in value, and the psychology of the buyer. While cosmetic improvements with a budget of 1-2% of the property's value almost always yield a positive return, expensive full renovations are risky. The key factor is an objective, data-driven analysis. Rather than relying on your intuition, you should have a precise assessment carried out. Strategic planning based on market data can make the difference between a €10,000 loss and a €30,000 gain. Use tools like the ImmoGPT chat for an initial assessment or a detailed Auctoa evaluation to unlock the full potential of your property. Make your decision based on facts, not assumptions.

Is it worth selling a property in its current condition?
That depends on the condition and the market situation. In a very high-demand market, selling 'as seen' might be worthwhile. However, keep in mind that buyers tend to demand price reductions of 10-30% for visible defects, which often exceed the actual repair costs.
Can I deduct renovation costs from tax?
If you sell the property within the speculation period of ten years and carry out renovations, the costs can be claimed as advertising expenses and reduce the taxable profit. Be sure to consult your tax advisor on this.
What's more important: a new kitchen or new windows?
In terms of value enhancement, new energy-efficient windows are almost always more important. They improve energy efficiency (required by GEG) and enhance living comfort. A new kitchen is a matter of personal taste and carries a higher risk that the investment may not match the buyer's preferences.
How can I determine which renovations are worthwhile for my property?
The best way is through an objective, data-driven analysis. A digital valuation service like Auctoa can simulate various renovation scenarios and calculate their financial impact on the potential selling price, helping you make an informed decision.
Should I use home staging before selling?
Yes, home staging is a very effective, cost-efficient measure. Through professional furnishing and decoration, the property becomes more appealing to a wider range of buyers, accelerating the sales process by up to 50% and increasing the price by 5-15%, according to studies.
What common mistakes should be avoided when renovating before a sale?
A common mistake is over-investing in projects that don't appeal to potential buyers. Avoid overly personal renovations and focus on neutral, value-enhancing measures such as energy efficiency or cosmetic repairs. Another mistake is failing to carry out a professional cost-benefit analysis.
