Compare the full consequences of changing the loan

Paying a mortgage down early can reduce borrowing, but the decision needs a full calculation. The repayment amount, any applicable compensation, the remaining term, your cash reserve and the cost of replacing the loan all matter. A lower advertised rate is not enough to establish that refinancing will save money.

Start with the agreement you already have. Spanish mortgage rules can depend on the contract date and type of transaction, so an online percentage should not be applied without checking the relevant regime. This guide helps organise a written comparison of staying, repaying partly, settling in full or changing the finance.

Establish the contract and proposed action

Collect the mortgage deed, later amendments, recent statements and current terms. Record the original date, any relevant change date, balance, remaining term, rate structure and associated products. If more than one person is liable, identify who must agree to a proposed change.

Describe exactly what you want to do. A one-off capital reduction is different from repaying the whole debt. Changing terms with the existing lender is different from moving to another lender. A sale that requires discharge of a registered mortgage introduces another administrative workstream.

Ask the lender and relevant adviser to confirm the applicable legal regime. Do not assume that every mortgage described as variable, fixed or Spanish has the same early-repayment provisions. Older agreements, later changes and the particular operation need their own assessment.

Use the current official framework

Banco de España’s early-repayment guidance explains the framework for loans signed after the entry into force of the 2019 mortgage law. It describes repayment rights, information and notice requirements, and limits on compensation that depend on the relevant circumstances and loan type.

This source was researched on 27 October 2026. Rather than treating its headline limits as a fee automatically payable in every case, ask the lender to identify the contractual provision, applicable law and calculation for your operation. Obtain advice where the agreement is older or the proposed change engages a different rule.

Obtain a dated settlement or repayment quote

Ask for the outstanding capital, interest to the proposed date, any compensation and other properly identified amounts. Make sure the quote has a validity date and explains how the figure changes if the payment arrives later. A statement balance is not necessarily the amount required to settle on a future day.

Request payment instructions through a verified channel. Confirm the account, reference, timing and process for acknowledging receipt. The larger the transfer, the more valuable it is to resolve administrative details before sending money.

Keep the quote and the lender’s explanation with the decision file. If you query a charge, record the response and revised calculation rather than silently editing the total. A comparison is useful only if it uses amounts that the lender has actually explained.

Compare a smaller payment with a shorter term

A partial repayment can affect the future schedule in different ways depending on the agreement and arrangements made. Ask whether the proposal reduces the instalment, shortens the term or offers a choice, and obtain the revised schedule for each available option.

Banco de España’s partial-repayment guide discusses the distinction between reducing payments and reducing the remaining term. Compare the household cash-flow effect as well as the interest calculation.

The mortgage calculator can illustrate constant-rate scenarios, but the lender should confirm the actual schedule, review mechanics and charges. Do not apply a simplified model to a changing-rate agreement and present its total as a guaranteed saving.

Protect the household cash reserve

Before making a voluntary repayment, update the wider budget. Include acquisition or sale costs, taxes, maintenance, community commitments and household emergencies. Money used to reduce the loan may not be readily available again if a major repair arrives.

Consider the currency in which savings and future income are held. Moving sterling into euros to make a repayment involves a separate exchange decision. Record the actual conversion cost and settlement timing without assuming that a future exchange rate will be more favourable.

A financial adviser can help assess the trade-off with other priorities. The purpose of the budget is to show the consequences of the choice, not to prescribe that every available euro should be used to repay debt immediately.

Distinguish changing terms from changing lender

Ask the existing lender what can be changed and on what conditions. Compare that proposal with a written offer from a potential new lender, keeping loan amount, term and relevant assumptions consistent. Record any new assessment, valuation or documentation required.

Do not assume a new lender will accept the property or borrower on the same terms as the current bank. Income, age, security value, existing obligations and underwriting criteria may all need reassessment. A marketing rate is not an approved refinancing facility.

Read the valuation guide and rate-structure guide when comparing offers. A lower initial payment can conceal a longer term, later variable rate or different associated costs. Those changes should be explicit in the comparison.

Build a complete refinancing comparison

List the costs of leaving the current arrangement and establishing the proposed one, using confirmed responsibility for each item. Keep one-off costs separate from recurring charges. Include relevant product costs and explain which amounts are estimates pending an offer.

Then compare payments and remaining balances over a sensible period. If the new loan runs longer, show what would still be owed at the same comparison date. Counting only the monthly reduction can exaggerate a benefit created partly by delaying capital repayment.

For a variable proposal, test more than one rate assumption. For a planned early sale, include the relevant exit questions. These scenarios do not forecast the future; they show whether the apparent saving is resilient to changes the household considers plausible.

Treat registry cancellation as a distinct task

Paying the bank does not by itself describe every step needed to remove a mortgage entry from the Land Registry. Ask the conveyancer what documentation, notarial or registration work is required in your circumstances, who will arrange it and what it will cost.

This is especially important when selling. The buyer’s team needs an agreed method to complete the sale and address the existing security. Coordinate the settlement amount, payment route, evidence and later registration work rather than relying on a general promise that the mortgage will be cancelled.

Keep proof of repayment and the documents relating to discharge. If a professional retains money for later expenses, ask for an eventual statement and return of any balance. A clear financial reconciliation should accompany completion of the administrative task.

Use a break-even example cautiously

Imagine a fictional refinancing proposal with one-off costs and lower expected monthly outgoings. Dividing those costs by the initial monthly difference can give a rough starting point for discussion. It is not a complete comparison if rates, terms, capital balances or associated products differ.

Prepare a dated table showing the existing arrangement, proposed arrangement, upfront costs, expected balances and assumptions. Ask the lender or adviser to explain the result over the period you actually intend to borrow. Label any uncertain saving clearly.

Use the tax-finance checklist to record the written quotes, legal regime, repayment options, reserve and discharge tasks. The useful outcome is a decision supported by actual contract information and a workable funding plan, with the consequences understood before the money moves.
