In the Algarve right now a new or fully renovated home costs roughly 20% to 35% more than a comparable resale, with about 25% as a working midpoint. That premium is the whole decision in one number, and whether it is worth paying comes down to three things most buyers only think about after they have made an offer.<\/p>\n\n
Buy new if you want low running costs, a legal safety net and no renovation project. Buy resale if you want a larger plot, an established location and the option to add value yourself.<\/p>\n\n
That is the short version, and for most of the buyers I work with it holds. The longer version is that the premium buys you three specific things, and if you do not want all three you are probably overpaying for the ones you do want.<\/p>\n\n
The Lagos median sits around \u20ac4,500 to \u20ac4,600 per square metre in 2026, and it has climbed through the year. Within that, Meia Praia and the front-line sea-view strip run \u20ac5,000 to \u20ac7,000, while Praia da Luz mostly sits between \u20ac4,000 and \u20ac5,500.<\/p>\n\n
Apply the new-build premium to that and a 120 m\u00b2 apartment that would be roughly \u20ac540,000 as a resale at the Lagos median lands closer to \u20ac675,000 new. That is \u20ac135,000, which is real money and deserves a real reason.<\/p>\n\n
One caveat on the premium. It is an average across the region, and it compresses at the top of the market. Above roughly \u20ac1m the comparison stops being new against old and becomes new against a large plot in a location that cannot be replicated, which is a different question entirely.<\/p>\n\n
This is the part of the decision that gets the least attention and probably deserves the most.<\/p>\n\n
Under Decreto-Lei n.\u00ba 84\/2021, when you buy from a developer or builder as a consumer you get a 10-year guarantee on structural defects<\/strong> and 5 years on everything else<\/strong>. If you commissioned the build yourself and contracted directly, the five-year period applies instead. You must notify the seller within a year of discovering a defect, and start legal action within three years of that notification.<\/p>\n\n Buy a 1990s villa from a private seller and you have none of that. You have the Civil Code provisions on hidden defects, which are far narrower and much harder to enforce against an individual who has taken the money and gone home to another country. In practice, on a resale, the survey is your warranty. Pay for a proper one.<\/p>\n\n Land. New development in the Western Algarve goes where planning permits, which is rarely the walkable heart of Lagos or the front row at Praia da Luz. If your priority is walking to the beach and a cafe rather than a heat pump, the older stock is where you will find it, and no premium buys you a position that is not for sale.<\/p>\n\n Plot size is the other one. A 1980s or 1990s villa in this region often sits on a plot a modern development would split into three. If you want space, a pool with room around it, and mature trees that took thirty years to get there, resale is usually the only route.<\/p>\n\n There is also a third option people forget: buy the land and build. I covered the numbers and the timeline in building a villa in the Algarve in one year with CLT<\/a>, and the 6% VAT rate on qualifying construction work<\/a> has made that route meaningfully cheaper than it was.<\/p>\n\n Ask yourself one question first: are you going to be here to manage problems?<\/p>\n\n If you are buying from abroad and visiting a few times a year, a resale with any question mark over it is a bad idea. Getting three quotes, chasing a builder and being present for the work is difficult enough living here, and close to impossible from Manchester or Amsterdam. That is the case for paying the premium and taking the warranty.<\/p>\n\n If you are moving over properly, have time, and want a specific street rather than a specific specification, resale gives you more house, more land and more location for the money. Just spend a fraction of what you save on a proper survey and a lawyer who will actually check the licensing, because that is where resale purchases go wrong in this region.<\/p>\n\n What I would not do is pay a 25% premium for a new build and then discover the thing you wanted was the location all along.<\/p>\n\nNew build against resale, side by side<\/h2>\n\n
