Introduction

Marbella rewards investors who understand its micro-markets, and renovation is one of the clearest ways to add value in a market where supply is tight and demand for turnkey homes is high. The question is rarely whether to invest, but how: buy something ready to use, or take on a project and create the value yourself.

This guide compares the two main strategies, sets realistic return expectations, and covers the costs and regulations that decide whether a project pays off.

Buy-to-rent or renovate-to-sell: which strategy fits your goal?

The right approach depends on what you want your capital to do. Buy-to-rent prioritises income and liquidity; renovate-to-sell targets a one-off capital gain. Neither is universally better, they serve different objectives.

• Buy-to-rent suits investors wanting steady income and a longer hold

• Renovate-to-sell suits those targeting a defined capital gain over 12 to 24 months

• Turnkey villas offer immediate use and rental income from day one

• Renovation projects offer a lower entry price and control over the finished value

A turnkey purchase removes execution risk but pays market price. A renovation lets you buy below the finished value and capture the difference, provided the numbers and the timeline hold. This is where professional project management matters most, keeping design, permits, build and budget aligned so the projected return survives contact with reality.

Is it smarter to buy new or renovate an older property?

With a budget of €500k to €700k, the choice usually comes down to location versus condition. Older properties in prime areas often sell below the cost of the equivalent new build, which is what creates the renovation opportunity.

• New builds carry a price premium but need no work and less oversight

• Older resales in prime pockets leave room to add value through renovation

• Renovation lets you buy a better location than the same budget buys turnkey

• The trade-off is time, permits and construction risk

In areas like Nueva Andalucía and the Golden Mile, where new supply is limited, buying an older property and renovating is frequently the only route into the postcode at a workable price.

What ROI can you expect from a Marbella renovation?

Returns depend on the entry price, the finish level and the exit, but the market fundamentals are supportive: prices are driven by structural supply scarcity, and demand for finished, move-in-ready homes is consistently strong.

• Investors flipping dated 1980s and 1990s villas commonly target returns above 20%

• Marbella villa renovation runs roughly €1,800 to €5,500 per m², well above city-apartment costs

• Construction costs have risen around 38% since 2020, so quotes should be re-confirmed at signing

• A €100k to €200k budget adds most value when spent on kitchens, bathrooms and layout

The projects that work are the ones costed accurately before purchase, not after. A realistic ROI target starts with a firm build quote and a clear view of the finished value, not an optimistic guess on either.

The costs and taxes that shape your return

Returns are decided as much by costs and tax as by the sale price, so build these in before committing.

One detail that directly affects flip returns: major improvement works (mejora) add to your cost basis and reduce the capital gains bill, while cosmetic maintenance does not. Keeping every VAT invoice is what preserves that deduction.

Renovating an apartment in Puerto Banús: the regulatory angle

High-demand areas like Puerto Banús carry rules that can make or break a rental-focused project. Since 2025, new tourist rentals in Andalucía need explicit community approval by a 60% vote, plus regional and national registration, so a renovate-to-rent plan should confirm the licence position before purchase.

• Tourist licences are tied to the property and transfer with the deed

• New licences now require a community vote, which is not always granted

• Buying a unit with an existing licence avoids the hardest hurdle

• Renovate-to-sell avoids licensing but faces capital gains tax on exit

Confirming the current regulatory position for a specific building is essential, as rules vary by community and are changing. This is a point to verify with legal advice rather than assume.

Getting the strategy and the execution right

The decision between renting and selling, and between turnkey and renovation, should follow your financial objective rather than the property that happens to be available. Helios Homes provides investment advisory to align that decision with your goals, and project management to deliver the renovation on budget and on time.
