Yes, you can move your existing Spanish mortgage to a cheaper lender in 2026, and in most cases it is far cheaper than cancelling and starting again. The main tool is subrogación de acreedor, a lender-to-lender transfer protected by the mortgage law Ley 5/2019 de Contratos de Crédito Inmobiliario, which caps the early-repayment penalty on variable loans at 0.15% in the first three years and 0% thereafter. On a typical Costa del Sol home you should budget roughly 0.5%-1.5% of the outstanding balance to switch, versus a far steeper bill if you cancel the loan entirely. If your rate was fixed above today's market, subrogación can genuinely save you money.
This guide explains the three ways to change your mortgage, what each costs on a Costa del Sol property, how non-residents fit in, and the exact steps. It applies equally to owners in Costa Blanca, Costa Cálida and Costa Almería, only the stamp duty bands differ slightly by region, and we flag those below.
Subrogación de acreedor ("change of creditor") is a legal transfer of your existing mortgage from one Spanish bank to another, keeping the same debt but on the new bank's terms. Under Ley 5/2019 your current bank is given the chance to match the offer (the "right to counter-offer", or enervación) within 15 days before the switch completes, so banks often improve your rate just to keep you.
It is different from subrogación de deudor, the far more common situation where a buyer takes over a developer's or seller's mortgage when purchasing. That is a purchase tool, and we cover the wider financing picture in our non-resident mortgage Spain 2026 guide. This article is strictly about owners who already hold a loan and want cheaper terms.
There are three routes, and the right one depends on whether you want to change bank, change terms, or both. Subrogación changes the bank; novación renegotiates with your current bank; cancelling and signing a new loan is the most expensive but sometimes the only way to borrow more.
| Route | Change bank? | Main costs | Can you borrow more? | Typical total on balance |
|---|---|---|---|---|
| Subrogación de acreedor | Yes | New valuation (tasación), lender's subrogation commission (if any), notary + registry; early-repayment cap under Ley 5/2019 | No, same debt only | ~0.5%-1.5% |
| Novación (same bank) | No | Novation commission, possible valuation, notary + registry on increased sums | Sometimes | ~0.1%-1% |
| Cancel + new mortgage | Yes | Cancellation deed + registry removal, plus full new-loan costs incl. AJD stamp duty where applicable | Yes | ~2%-4% |
Crucially, under Ley 5/2019 the AJD stamp duty and notary/registry costs of setting up a mortgage are paid by the bank, not the borrower. The borrower only pays the tasación (property valuation). That single rule is why subrogación and novación are so much cheaper than they were before 2019, many older online articles still quote borrower-paid stamp duty that no longer applies.
For loans signed after June 2019 the penalties are capped by Ley 5/2019, and they are low. On a variable-rate mortgage the lender may charge at most 0.25% of capital repaid in the first three years, or 0.15% in the first five years (the bank picks one bracket), and 0% after that. On a fixed-rate mortgage the cap is 2% in the first 10 years and 1.5% afterwards, and only up to the lender's actual loss.
If your loan pre-dates 2019 the older penalty rules in your deed still apply, read your escritura, or check the outstanding debt on a current nota simple, which lists the registered charge against your property.
It is worth it when the rate gap, applied to your remaining balance and term, saves more than the switching cost, usually a saving of at least 0.5-0.75 percentage points justifies the move. The reference rate for most Spanish variable loans is the 12-month Euribor, published by the Banco de España; fixed and mixed deals price off bank funding. If you locked a high fixed rate during the 2023-2024 peak, a cheaper fixed or a mixed deal today can repay its costs within a couple of years.
Run the numbers on the full remaining term, not just the monthly payment. A lower rate stretched over a longer term can cost more overall. Also watch for bonificaciones, rate discounts tied to holding home insurance, life cover or payroll with the bank; the headline rate only applies if you meet them.
Suppose you owe €200,000 on a Costa del Sol apartment at a fixed 4.1% with 20 years left, and a new bank offers 2.9% via subrogación. The switch might cost around €1,500-€2,500 (valuation plus any commission, with the bank covering stamp duty and set-up). The rate cut saves well over €1,000 a year in interest early on, so the cost is typically recovered inside two years. Always confirm your own figures with a broker or the lender.
Yes, but the new bank re-assesses you as a fresh applicant: income, debts and loan-to-value all count again. Non-residents usually face lower maximum loan-to-value, commonly around 60-70% of the valuation, so subrogación works best where you have built equity or your home has risen in value. You will need a valid NIE (see our NIF vs NIE guide), a Spanish account, and proof of income.
Currency matters too: if your income arrives in sterling or dollars, exchange-rate swings affect affordability. We explain hedging options in our currency risk guide for British buyers and the mechanics of moving funds in our sending money to Spain guide.
Every subrogación or new mortgage needs a fresh tasación, an official valuation by an appraiser approved by the Banco de España. The bank lends a percentage of this figure, not of your purchase price, so a rising market helps you and a falling one can shrink the deal. On the Costa del Sol, values in sought-after zones have generally held firm, which usually works in an owner's favour. We explain how appraisers work and why their figure can differ from the sale price in our tasación guide.
The whole process typically takes four to eight weeks. The notary and completion mechanics mirror a purchase, see our notary and completion day guide for what happens at the table.
Pure subrogación and novation of the rate carry no stamp duty for the borrower. But if you increase the capital (borrowing more against the home), the extra amount can attract AJD stamp duty, which in Andalucía (Costa del Sol and Costa Almería) runs at 1.2%, versus 1.4% in the Comunidad Valenciana (Costa Blanca) and 1.5% in Murcia (Costa Cálida), per the respective regional tax rules. If you are only chasing a better rate on the same debt, this does not apply.
Mediter currently has 9,755 properties for sale across the Costa del Sol, Costa Blanca, Costa Cálida and Costa Almería. Owners refinancing to buy a second home, or releasing equity to upgrade, are common on the Costa del Sol, and if you are considering trading up rather than remortgaging, our rent vs buy comparison and the Estepona investment guide are useful starting points.
Yes. You can arrange a subrogación as a non-resident, but you will need a valid NIE, a Spanish bank account and to pass the new bank's affordability check. A power of attorney can allow a lawyer to sign on your behalf if you cannot travel for completion.
Under Ley 5/2019 your bank has 15 days to counter-offer once a subrogación is notified. It cannot block the switch, but it can match or beat the new deal, which often means you get a better rate without even changing bank.
For a subrogación you mainly pay the tasación (valuation) and any lender subrogation commission, typically totalling around 0.5%-1.5% of the balance. The bank pays the AJD stamp duty and set-up costs. Cancelling and taking a new loan costs more, roughly 2%-4%.
Subrogación moves the loan to a new bank; novación renegotiates the terms with your existing bank. Novación is often cheaper and faster if your current bank will offer a competitive rate.
Yes, the 12-month Euribor published by the Banco de España is the reference for most variable Spanish mortgages. Many owners now compare it against fixed and mixed deals before deciding whether to switch.
Not through a pure subrogación, which only transfers the existing debt. To release equity you need a novation with a capital increase or a new mortgage, and any extra borrowed may attract AJD stamp duty at your region's rate.
