If you already have a mortgage on a Spanish property, you are not locked into the same rate and bank forever. Refinancing — either by moving the loan to another lender or renegotiating with your current one — can lower your monthly payment, change from variable to fixed (or the reverse), or unlock better terms if your personal situation has improved since you first signed.
It is not always the right move. Refinancing carries costs, and the maths only works if the savings over time outweigh the fees you pay upfront. This guide explains the Spanish terminology, typical scenarios where refinancing makes sense, and what non-residents should expect.
Subrogación vs novación — two Spanish terms to know
Spanish law and banking practice distinguish two main routes:
- Subrogación — transferring your existing mortgage to a different bank. The new lender pays off the old loan and registers a new mortgage deed. You change institution, and usually rate, term, or product type at the same time.
- Novación — modifying the terms of your loan with the same bank — for example switching from variable to fixed, extending the term, or renegotiating the interest margin without moving lender.
Both are forms of refinancing in everyday language, but the paperwork, fees, and timeline differ. Subrogación involves a full bank switch; novación is often simpler if your current lender is willing to compete for your business.
When refinancing may make sense
Common scenarios we see among international owners on the Costa del Sol:
- Interest rates have fallen since you signed — if market fixed rates are materially lower than your current payment, subrogación to a new offer may save money over the remaining term. We do not quote live rates here; compare current offers against your existing deed with an advisor.
- You moved from non-resident to tax-resident — Spanish residents often access higher LTV on new purchases and sometimes more competitive refinancing terms. If you originally borrowed as a non-resident at 70% LTV with a shorter fixed period, becoming resident may open novación options worth exploring.
- You want to change product type — switching from variable (Euribor-linked) to fixed for payment certainty, or from fixed to variable if you plan to sell within a few years. Our guide on fixed vs variable mortgages covers the trade-offs in detail.
- Your income profile improved — higher declared earnings or a shift from self-employed to employed status can make you eligible for a better margin, even without a dramatic rate move in the market.
Costs to factor in before you switch
Refinancing is rarely free. Depending on the route and your original contract, you may face:
- Early repayment or cancellation fees on the existing mortgage — common on fixed-rate tranches, often capped by law but still meaningful
- New bank arrangement fees if you subrogate to another lender
- Notary and land registry costs for registering the new or modified deed — typically required on subrogación
- Fresh valuation (tasación) requested by the incoming bank
A simple rule: estimate total switching costs, divide by your expected monthly saving, and see how many years until you break even. If you might sell the property within that window, refinancing may not pay off.

Non-residents and refinancing
Banks that lent to you as a non-resident may apply similar criteria on refinance — proof of overseas income, NIE, and property in good standing. If you remain non-resident, do not assume resident-only promotional rates apply. If you have become tax-resident in Spain, tell the advisor upfront; your file may be reassessed under resident rules, as outlined on our non-resident mortgage guide (which also covers when resident terms differ).
Matching the right bank matters as much on refinance as on first purchase — see our overview of how to choose a lender for non-resident mortgages for the same profile-matching logic.
Can non-residents refinance as easily as residents?
Generally, non-residents can refinance, but the process resembles a new underwriting review — income proof, property valuation, and compliance checks. Residents may see a wider product range and sometimes lower margins. Non-residents should expect similar documentation to the original application and allow several weeks for approval. Not every bank actively markets non-resident refinance products; a broker helps identify willing lenders.
Is there a minimum time before I can refinance?
There is no universal legal waiting period, but your existing mortgage contract may impose early-repayment penalties during an initial fixed period — often the first few years. Some banks also require a minimum period of payments before subrogación. Read your original deed or ask your lender before applying elsewhere. If penalties are high, novación with the same bank may be cheaper than a full switch.
