Three-bedroom penthouse with 69 m² solarium, central Torrevieja

Top-floor penthouse in a small Sol Diamante S.L. promotion on the corner of Calle Clemente Gosalvez and Calle Ramon Gallud — the dense, walkable retail spine of central Torrevieja. The building is post-2014 build with full architect-certified delivery, four storeys plus two penthouses on top. This is the one that opens to C/ Clemente Gosalvez.

The unit comes vacant and turn-key: marble flooring throughout, dark-stained interior joinery, aluminium exterior joinery with thermal break, three full bathrooms — one of them done in travertine, another in mosaic tile — and a clean kitchen ready for the next operator’s fit-out. Nothing about the unit needs work to be lived in or rented out from day one.

Spatial logic — why this works as an investment

146 m² of useful area split across three bedrooms, three baths, a 53 m² living-dining room and a separate office kitchen. Above all that, a 69 m² private solarium covering the upper-roof footprint of the unit — large enough to install a small pool, an outdoor kitchen, or a year-round outdoor living zone, which the short-stay market rewards strongly at the nightly tier this property aims at.

We treat this asset under two investor frames:

• Owner-occupied + occasional short-stay rental. The classic Costa Blanca penthouse use — the buyer keeps it for personal weeks in shoulder months, lets it during the high season. The solarium is the rate-multiplier here.
• Pure short-stay rental. Three-bed plus three-bath units inside the centre are a scarce product on Airbnb / Booking; the dominant supply in Torrevieja is two-bed, one-bath. Pricing power follows.

A long-term residential lease is also possible, but on a unit of this finish quality and footprint, the short-stay model materially outperforms long-term in our standard underwriting.

Rental model — indicative numbers at €580,000

The figures below are how we’d underwrite this unit on day one of letting under short-stay, no fit-out upgrades, no rate-leadership assumption. The aim is to give you a defensible floor, not a sales projection. Final numbers shift with your tax residence, acquisition vehicle and licence path — we rebuild the model live on the discovery call.

• Blended ADR ≈ €160 / night — weighted across high season (€200–230), shoulder (€130–160) and low season (€80–100).
• Annual nights booked ≈ 225 (62 % occupancy) — what a competent operator in central Torrevieja achieves on a 3-bed, 3-bath turn-key unit by year two.
• Gross rental income ≈ €36,000 / year.
• Operating costs ≈ €18,500 / year — OTA fees (~10 % blended), cleaning, utilities, supplies, 15 % management, IBI, community, insurance with STR rider, licence and accounting, plus a 0.5 % maintenance reserve on the asset value.
• Net rental, pre-tax ≈ €17,500 / year.
• Gross yield on asking price ≈ 6.2 %.
• Net yield, pre-tax ≈ 3.0 %. Modelo 210 at 19 % on net (EU/EEA-resident profile) trims that to ≈ 2.4 % post-tax.

For comparison, a long-term residential lease on this unit underwrites at roughly €1,900 / month gross (≈ €22,800 / year), netting to ~2.4 % pre-tax once costs and IRPF/Modelo 210 are applied. Short-stay wins by ~60 basis points net on these assumptions, with materially more operational work.

How we run the file

Asking price is €580,000. The full investment memo modelled to your tax residence and intended use is part of the discovery-call deliverable — net yield, Modelo 210 setup, plusvalía exposure, short-stay licence path, the lot.

A second penthouse in the same building (door 4B) is also available at €899,000 — different footprint, larger solarium, two baths instead of three. We model both side-by-side on request.

What we still verify together

• Current short-stay licence status on this unit and the community-of-owners minutes on tourist-rental authorisation.
• Your tax residence, so the underlying net-yield assumption matches your real deduction profile (EU/EEA vs UK/US treatment under Modelo 210).
• Whether you intend to deploy through a personal name or a Spanish SL — the ITP / corporate-tax overlay shifts the answer.
