Renovate before selling, or sell as-is?

It helps to separate two different things first. A cosmetic refresh — paint, deep cleaning, small repairs, decluttering — is cheap, quick, and almost always worthwhile, because it makes the property more presentable at viewings. A real renovation — replacing a bathroom, kitchen, or wiring and plumbing, changing flooring — is expensive, takes weeks to months, and carries a real risk of not being fully recovered in the price.

The closer a renovation gets to structural or hidden elements (wiring, pipes, waterproofing), the harder it is to estimate in advance how much it will cost and whether a buyer will even perceive the difference compared with simply discounting the price.

Budget: do you have cash available, or would the renovation need a loan that weighs on the deal. Time: can you wait for the renovation to finish, or does the property need to go on the market now. Risk: how confident are you that the specific improvements will appeal to the typical buyer for this property, not just to you.

• If the budget is limited — prioritise only a cosmetic refresh and small repairs.
• If time is critical — selling as-is with a correctly reflected price is often faster.
• If the risk of not recovering the spend is high (non-standard choices, high-end materials for a mass-market property) — a full renovation rarely pays off.

As a hypothetical example, suppose an apartment would sell as-is for €95,000. The owner is considering a renovation costing €8,000 (bathroom and painting), expecting a higher price. For this to be worthwhile, the renovation must bring in at least what was spent, plus the time lost waiting and any loan interest if one is used.

In this hypothetical scenario, the renovation does not fully pay off — the price difference does not cover the cost, let alone the time. The lesson is not that renovation is always a mistake, but that the sums should be done with specific figures, not assumed ones.

The market segment matters — in higher price brackets the gap between a renovated and an unrenovated property usually carries more weight than in a more affordable one. The condition of the building, the floor, and the location also frame what a buyer expects as standard and how much they are willing to pay extra for it.

For an apartment in a panel or brick block, buyers usually compare directly with other listings in the same building or area, so a cosmetic refresh is often enough to stop the property looking worse than the competition. For a house with a garden the decision is more complex, because besides the interior, the façade, roof, and garden are also assessed — elements that are hard to 'hide' with paint alone and can weigh more heavily during viewings.

For a property intended mainly for renting out rather than selling, the calculation differs — there the renovation is compared against the expected rental yield rather than just the sale price, so the horizon for recovering the investment can be longer.

Do a short calculation like the example above with your own, not hypothetical, figures: a current valuation of the property, an actual renovation quote, and a reasonable estimate of how much more a buyer would pay. If the gap is small or uncertain, a cosmetic refresh is often the safer choice. More guidance on preparation itself is in preparing a property for sale.
