Painting before selling or renting: where to invest

The Portuguese real estate market is different from a year ago. Buyers take longer to decide, compare more options, and notice details that previously went unnoticed. This changes how it makes sense to prepare a home before putting it up for sale or rent, and painting is usually one of the most cost-effective decisions, provided it is done carefully and not in every room equally.

Why painting matters more in a slower market

Homes take longer to sell

Between July and September, the average announced selling price of housing in Portugal increased 3.4% compared to the previous quarter, reaching 3,666 euros per square metre, while the average time to sell apartments grew 25%, reaching 132 days.1 This means a property remains exposed to visits and direct comparisons with other options on the market for longer, which makes the state of the walls an increasingly visible detail.

Buyers are more selective and rational

The 2026 buyer is more informed, more cautious, and less influenced by emotional movements, and recent experience has shown that decisions made under pressure can have significant costs.2 This reinforces the idea that small faults, such as yellowed walls, damp stains, or peeling paint, can weigh more on the decision than they would have done a few years ago.

Not all homes sell at the same pace

Analysis of listing duration on the real estate portal shows that 18% of homes were sold between one week and one month, 27% between one and three months, and 37% between three months and one year.3 The difference between a property that sells quickly and one that drags on the market for months often lies in presentation details, and painting is one of the easiest to correct without significant investment.

Where painting really pays off before selling or renting

The rooms visitors evaluate first

The entrance, living room, and kitchen are usually the rooms that weigh most heavily in the first impression, because they are the first to be seen and set the tone for the rest of the visit. Walls with uniform colour, without marks from old furniture or visible water damage, help visitors imagine themselves living there, without being distracted by obvious issues.

What typically doesn't pay off painting thoroughly

Not everything requires complete renovation. Some examples of where a larger investment rarely translates into proportional returns:

• Storage areas, pantries, or other rarely visited technical spaces
• Walls already in good condition, just with a slightly outdated tone
• Rooms that the buyer or tenant will probably alter to their taste

In these cases, careful cleaning and small targeted touch-ups are usually sufficient, freeing up budget for areas that really influence the decision.

Neutral colours as a safe choice

Neutral and light tones remain the safest bet for those who want to sell or rent, as they facilitate the projection of those who visit and do not compete with the home's natural light. This logic is also detailed in the article on wall preparation for photos and visits4, which complements this choice with specific tips for the photography session.

Damp and degraded walls: what can stop a sale

Stains that buyers won't overlook

Damp stains, mould, or crumbling plaster are among the signs that most deter interested parties, as they suggest structural problems even when they are only superficial. Before painting over them, it is important to understand if the source has been resolved, especially because painting over active damp can be premature5 and may compromise the work shortly after completion.

When it's worth calling a specialist

If there are recurring stains, a musty smell, or loose plaster, the solution usually involves damp removal6 before any new coat, to ensure the problem doesn't reappear a few months after the sale or start of the tenancy.

Comparing scenarios: targeted painting vs complete painting

The following table summarises the most common scenarios for those preparing a home to sell or rent:

For those who decide to proceed with a wider intervention, interior painting7 work can be quoted per square metre, but this type of quote is always indicative, never definitive, because two walls with the same area can be in very different conditions (cracks, damp, degraded plaster). The final value can only be confirmed after assessing the real state of the surfaces, whether through photos and videos or an on-site visit, both of which work in the same way. This is why our platform always requests photos and videos of the surfaces before finalising any quote, precisely to avoid surprises during the work.

Next step: decide based on your sales timeline

Before requesting quotes, it's worth answering three simple questions:

1. Which rooms will most visitors see in the first weeks of the listing?
2. Are there signs of damp or degradation that need to be treated before painting?
3. Does the timeframe until the first visit allow for proper drying and ventilation between coats?

With these answers, it's easier to decide between a quick touch-up, painting the main areas, or a complete intervention. Whatever the choice, it's important that the scope of work is recorded in writing. On our platform, all service details are online, visible to the client, the professional, and the platform, which prevents misunderstandings about what was agreed before the sale or rental.
