Cash or mortgage — which costs more in Spain

In short

Preserving wealth: why paying cash can be the expensive option

Buyers who could pay cash rarely ask whether they should. The question is worth asking, for three reasons that only become visible after the purchase.

1. The capital is walled in

A paid-off Spanish property is not liquid wealth. Getting the capital back out leads into the narrowest part of the market: only two of 15 to 20 lenders approached will lend against an unencumbered property for a non-resident, as a rule up to 50 per cent of the valuation, with the use of funds documented (Perini Market Check, 01.09.2026). At the time of purchase, 60 to 70 per cent would have been available. Twenty percentage points of the property value — created purely by sequence.

2. Spanish wealth tax is charged on net assets

Non-residents are liable to Spanish wealth tax on their Spanish assets, with a solidarity levy on large fortunes above certain thresholds. What matters is net wealth: debt secured on the property is in principle deductible. A financed property and a cash-bought property are therefore not equivalent for tax, even at identical value. How much it matters depends on the Autonomous Community and the allowances — it should be calculated, not assumed.

3. Spread beats concentration

A million paid in cash is a million in one property, in one country, under one legal system. Financing the same property at 60 per cent keeps the larger part of the capital available — for the next opportunity, for purchase costs of 10 to 13 per cent, for the reserve every foreign property eventually needs.

This is not an argument for debt. It is the observation that in Spain, cash-or-finance is a one-time decision. It can only be corrected afterwards on distinctly worse terms — and with most lenders, not at all.

Not tax or legal advice. Wealth tax, allowances and the deductibility of debt vary by region and must be assessed case by case.
