Things get wild in Selwo because of the neighbours alone: the Selwo Aventura wildlife park is right next door. Wild but true is also the market. In Selwo a New Build costs 11.7% less than a Resale: €5,302 per square metre against €6,004.

Most buyers expect new to cost more than second-hand. In Selwo, on Estepona's New Golden Mile, it is the other way round. The reason is a Resale market that has almost quadrupled in ten years and a New Build supply priced below it.

124 new units in 15 projects

Selwo has one of the larger New Build supplies among Estepona's zones. On 18 September 2026, 124 units in 15 projects were priced, from apartments to townhouses. Where so many projects are selling side by side, developers price competitively, which keeps New Builds below the level that Resales in the same location have now reached.

Where is Selwo, and what makes the location?

Selwo is on the New Golden Mile between Estepona and Marbella: green, quiet and family-friendly. The location combines four things that matter to buyers:

  • Wildlife park next door: Selwo Aventura is right in the neighbourhood.
  • School nearby: the Atlas American School is in the area, an argument for families.
  • Beach and centre in minutes: the beaches of the New Golden Mile and Estepona's town centre are quickly reached.
  • Fast connections: the A-7 leads to Marbella, Sotogrande and Gibraltar.

The New Golden Mile is the stretch of coast between Estepona and Marbella. The Selwo zone also includes developments near the beach such as Bahía del Velerín and Cabo Bermejo.

Selwo against Marbella: the New Golden Mile at half the price of the Golden Mile

New Builds in Selwo cost around half per square metre of what is asked on Marbella's Golden Mile. On 21 September 2026 the New Build median on the Golden Mile was €9,969 per m², in Nueva Andalucía €8,247 and in San Pedro de Alcántara €5,677.

Selwo is also below San Pedro, Marbella's westernmost and least expensive New Build area. For buyers looking on the coast between Estepona and Marbella, Selwo is one of the least expensive locations with New Builds.

Why are property prices rising in Estepona?

Because the town is growing, investing without debt, and demand comes from people who live here all year. Selwo benefits as one of the town's most sought-after locations.

Almost 13,000 new residents since 2016

Estepona's population rose from around 67,000 in 2016 to almost 80,000 in 2025, an increase of 19.4%. Marbella grew by 13.5% over the same period. Every new resident needs a home for the whole year.

Debt-free, with record investment

According to the town hall, the town has fully repaid an inherited debt of more than €300 million and is investing around €27 million in its 2026 budget. This includes a town-funded hospital for €15 million, a coastal corridor of more than 21 kilometres and the Bulevar Parque Central for almost €10 million. At the same time property tax for registered households is falling by 20% on average.

Rents are rising too

Long-term rents in Estepona stood at around €21 per m² per month in August 2026, 117.7% above their level five years ago. Rents and purchase prices have developed on the same scale. The price level is backed by use, not just by expectations, and this applies particularly to Selwo with its families and year-round residents.

Rental yield and holiday lets in Selwo

Long-term rents in Selwo stood at around €22 per m² per month in August 2026, and the gross rental yield on Resales was 4.39%. Rents there rose by 113.6% over five years. Because the New Build price is below the Resale level, the yield on the New Build price is higher: €22 per m² per month gives €264 a year, around 5.0% on €5,302. For a 100 m² apartment the average long-term rent comes to around €2,200 a month.

For holiday lets we measure how many of the offered nights comparable properties nearby were actually booked. For three-bedroom apartments and houses in Selwo, nightly rates in September 2026 were €217 to €251, with 32% to 46% of offered nights booked over the year. In Andalusia a holiday let requires registration in the tourism register and the consent of the owners' community.

What buyers also get with a New Build in Selwo

Besides the lower price per square metre, a New Build offers statutory guarantees that a Resale does not. Spain's Building Act, Ley 38/1999, requires all deposits from the building permit onwards to go through a special account and to be covered by a bank guarantee or insurance, including taxes and interest. After handover there is a warranty of one year for finishing defects, three years for habitability and ten years for the structure.

On top of that come today's building standard with insulation, glazing and air conditioning for summer and winter, and an owners' community without old debts. Purchase taxes: New Build 10% VAT plus 1.2% stamp duty, Resale 7% transfer tax. Even including taxes, New Builds in Selwo remain cheaper: around €5,896 per m² against around €6,424 for Resales.

What does this mean for investors?

In Selwo investors buy new buildings below the Resale price, in Estepona's fastest-growing district. The 11.7% gap is a buffer on entry, and the yield on the New Build price is around 5% gross. How New Builds and Resales compare across Estepona and in Punta Plata is shown in our note Estepona: New Builds cost only 2.9% more than Resales, the comparison with neighbouring towns in Costa del Sol: more m² for your money.

These are past figures, not a forecast. The drivers behind them, a growing town, a sought-after location and rising rents, are structural and not tied to a single period.
