Local data
Price data
Transfer tax in Spain is set by each autonomous community, not centrally — the same €1m purchase costs materially more in some regions than others. These are the figures that apply to a San Sebastián purchase.
Official price per m² and purchase taxes for San Sebastián, Q2 2026
Source for price per m²: Ministerio de Transportes y Movilidad Sostenible (MITMA), Valor tasado de la vivienda libre, Q2 2026 (published September 2026). Figures are the official average bank-valuation price of private housing (vivienda libre), in euros per m², for municipalities over 25,000 people or, where a town is not published, the province or region shown. Valuation prices usually sit below portal asking prices. Tax rates are the headline rates published by each autonomous community. Guidance only — not tax or legal advice; confirm the rate applying to your purchase with your Spanish lawyer.

Frequently asked
Yes. Non-residents — including US, UAE, UK and European buyers — can typically borrow up to 65% of value on San Sebastián property through Spanish and international lenders. San Sebastián is one of Spain's most supply-constrained prime markets, with values per m² rivalling central Madrid.
Around 35–40% of the price in cash, plus purchase costs and taxes on top. Funds must be traceable and evidenced before a lender will issue a formal offer.
La Concha and the Centro, Gros, Ondarreta, Antiguo, Ategorrieta and Igueldo are all well-evidenced lending locations. Less liquid or rural stock is still financeable, usually at a slightly lower loan-to-value.
Yes. Short-term bridging is regularly arranged for off-market and auction purchases, refurbishment projects and to bridge a home-country sale, typically over 6–24 months.
Yes. Selected international lenders will lend in GBP or USD, or offer multi-currency facilities, against San Sebastián property — useful where your income is not in euros.
Yes. Lenders typically want two to three years of accounts or tax returns; company directors can combine salary, dividends and retained profits.
Plan for eight to fourteen weeks from full application to notary. Bridging can complete in two to four weeks where a deadline demands it.
Yes — both are required to sign at notary and draw down a Spanish mortgage. We coordinate NIE, bank account opening, lawyer engagement and FX alongside the finance.
The city is hemmed in by hills and the sea, so buildable land is scarce. Frontline La Concha stock regularly exceeds €9,000/m², which shapes both valuation and lender appetite.
National banks compete with Basque regional lenders, and above roughly €1.5m private banks will look at interest-only structures against a broader relationship.
Yes. Gipuzkoa sets its own transfer-tax rules — broadly 7% on resale purchases — separate from the state regime, so your lawyer should confirm the applicable rate for your structure.

Before you apply
Identity and NIE, two years of income evidence, six months of bank statements, source of wealth and the property paperwork — our free checklist sets out every document Spanish lenders ask international buyers for, by applicant profile.
Also consider bridging
Non-resident Spanish mortgages typically take 8–14 weeks. Where timing is tight — auctions, off-market deals, chain-breaks or a pending home-country sale — short-term bridging can complete in 2–4 weeks and refinance onto a mortgage later.
