Renovation as a property investment strategy

Before selling a property, renovating to increase its value is a common strategy. However, the effectiveness of renovations depends on various factors such as the price per square meter in the area, the general condition of the property, the DPE (energy performance diagnosis), the finishing level, and the market tension.

Financial challenges of renovation

The seller faces a paradox: renovations can increase the property's price, but their cost must be covered before the sale, which many owners find difficult as their savings are often already invested in the property.

Personal renovation loans as a solution

To address liquidity issues, a personal renovation loan can be used to spread the expense, provided that the monthly payments are compatible with the household budget. For example, Banque Populaire offers a personal renovation loan up to 75,000 euros, with a fixed rate and a duration of up to 120 months.

Funding availability and flexibility

The funds can be available within 8 to 14 days for a defined project or released in installments over six months for projects still in the cost estimation phase.

Most profitable renovation works

The most profitable works are those that correct sales obstacles such as poor energy diagnosis, neglected maintenance, or outdated bathrooms. Small works with a strong impact, such as light painting, restored floors, and tidy storage, can enhance the first impression of the property.

Home staging and energy performance

Home staging can help sell the property more easily at the requested price by limiting negotiation arguments. Energy performance has become a significant price criterion. According to a SeLoger study from May 2025, a property with a poor energy diagnosis can have a price discount of 452 euros per square meter compared to a property classified D.

Impact of energy diagnosis on sales

The average selling time of a thermal leak is also extended by 5 days compared to a less energy-intensive property. However, the market value of a property tends to be higher if its energy label improves.

Renovating kitchens and bathrooms

Renovating the kitchen and bathroom can be effective if done to refresh rather than redo. Replacing taps, handles, or damaged countertops can have more effect than a complete renovation. Rebuilding these rooms risks overinvestment if the buyer is likely to modify them.

Market-specific renovation strategies

In tight markets like Paris, a well-targeted refresh can reduce negotiations and speed up the sale. In the provinces, the energy bill and future cost of works weigh more in the purchase offer, but the price per square meter is generally lower, making heavy projects harder to amortize.

Avoiding over-renovation

To avoid over-renovation, it is important to compare the renovated property with three to five recent sales of comparable properties in the same area. The classic error is to reason in terms of construction cost without checking the market ceiling.

Calculating net gain and return on investment

The net gain can be calculated as (price after works - price as is) minus (net cost of works + unforeseen + interest + transportation fees + possible temporary relocation). The return on investment corresponds to the net gain divided by the total cost of the operation.

Categorizing renovation works

Works should be classified into three categories: essential repairs that hinder potential buyers, measurable works that improve the DPE or functionality, and heavy and expensive aesthetic works. Essential repairs should be addressed first for a controlled cost.

Managing heavy renovation projects

For heavy works, having several quotes prepared and presenting them to buyers can help reassure them about the feasibility of the works.
