# Mortgage Affordability Calculator — Marbella 2026

How much Marbella property can you actually afford as a non-resident? This calculator uses the 2026 Spanish bank lending policies that Sabadell, Bankinter and BBVA actually apply on real Costa del Sol mortgage files — not the optimistic numbers you see on US or UK calculators that assume 90-95% LTV and ignore Spanish DTI rules.

The numbers change meaningfully depending on your residency status. A Spanish tax resident borrowing on Spanish-source income gets up to 80% LTV. A non-resident — most international Marbella buyers — is capped at 60-70% LTV, and Spanish banks haircut foreign-currency income (USD, GBP, CHF) by 10-15% when underwriting. Beckham-law residents sit in a special bracket at around 65% LTV because their tax-treaty status complicates the bank's debt-service stress test.

## How It Works

The calculator applies three Spanish bank policy levers to your inputs:

**Loan-to-value (LTV) cap.** This is the maximum loan as a percentage of the lower of property purchase price or bank tasador valuation. For 2026, Spanish high-street banks are lending:
- Non-residents: 60-70% LTV (we use 70% as the workable upper bound for well-prepared files)
- Spanish tax residents: up to 80% LTV
- Beckham law residents: 65% LTV (bank stress-tests their post-Beckham income exposure)

**Debt-to-income (DTI) cap.** Spanish banks underwrite to a maximum 35% of gross monthly income going to total debt service — that includes the new mortgage payment plus any existing loan payments, credit card minimums, or active personal lines. This is a hard cap; even strong buyers with high net worth get bounced if the DTI math doesn't work.

**Interest rate.** Q1 2026 fixed rates from the major Spanish lenders sit in the 3.5-4.5% band for non-residents, with the cleanest files (high deposit, simple income, EU passport) closer to the floor. The calculator default is 4.0%, which is the realistic middle. Use the slider to stress-test what a rate move would do to your ceiling.

The math is then standard amortisation: maximum monthly payment = (gross income ÷ 12 × 0.35) − other monthly debts. Maximum loan = monthly payment × ((1 − (1 + r)^−n) ÷ r), where r is the monthly rate and n is the term in months. Maximum property price = (max loan ÷ max LTV) + your deposit.

The output also tells you whether you are **deposit-constrained** (you have room for a bigger mortgage but not a bigger property) or **income-constrained** (a larger deposit would unlock a higher price). This matters because the right next move depends entirely on which way your bottleneck sits.

## What the Calculator Doesn't Capture

The 35% DTI / LTV math is the gateway test, but Spanish underwriting layers six more checks on top of the affordability calculation. None of these are in the calculator — but all of them affect whether your offer actually closes:

**Currency-of-income vs currency-of-loan mismatch.** If you earn in USD or GBP and want a EUR mortgage, the bank will haircut your income 10-15% to buffer against FX risk. Some banks also require that 30-50% of the loan principal be currency-hedged at signing. Always disclose income currency at the first conversation.

**Age vs term.** Spanish lenders typically cap the loan term so the borrower is no older than 70-75 at maturity. A 60-year-old applying for a 30-year mortgage will be steered to a 15-year term, which roughly doubles the monthly payment and dramatically cuts the affordable price.

**Asset mix and source-of-funds documentation.** The bank wants to see the deposit + 12-15% transaction-cost buffer (taxes, notary, registry, lawyer) sitting in a verifiable account, with documented origin of funds. If the cash arrived by gift, business sale, or property sale, you need the supporting paperwork. Crypto-source funds remain a hard sell at most Spanish high-street banks in 2026 — go through a smaller specialist or a Gibraltar-Spain bridge structure.

**Property type and bank appetite.** Banks are conservative on rural land, plots without imminent build permits, off-plan units, and ultra-trophy properties (>€10M). For these you need a private bank or a wealth-management mortgage line — not a high-street loan.

**Beckham law impact on borrowing capacity.** If you are inside the Beckham regime, your Spanish-source income is taxed at the favourable flat rate but your worldwide income visibility to the Spanish bank is reduced. This can paradoxically reduce your borrowing ceiling. Read the [Beckham law 2026 changes](/articles/article-beckham-law-2026-changes) for the full structure trade-offs.

**Existing Spanish debts.** Any open Spanish loan, even a small consumer line you opened five years ago and forgot about, shows up on the CIRBE central credit registry and counts toward your 35% DTI. Pull a CIRBE check before applying — you might need to close inactive lines first.

## Total Costs of a Marbella Purchase

Affordability is the loan side. The all-in cost of acquisition runs **transaction costs of 11-13% of the property price on top** of the headline number:

- ITP (transfer tax for resale) or VAT (for new builds): 7% (resale, Andalusia) or 10% (new build) plus 1.2% AJD
- Notary fees: 0.3-0.5%
- Property registry: 0.2-0.4%
- Lawyer: 1-1.5% (recommended for international buyers)
- Bank arrangement fee: 0.5-1.5% of the mortgage
- Tasador valuation fee: €400-800
- NIE certificate processing: €100-300

So a €2M acquisition lands at roughly €2.2-2.25M total cash outlay. The calculator gives you the property price ceiling — budget the transaction-cost buffer separately when planning your deposit. Our [2026 buyer guide](/buyer-guide-2026.html) has the full breakdown by zone and property type.

## What Happens Next

Three soft next steps after you have your number:

1. **Email yourself the calculation** via the soft capture form on the page. We send the full breakdown plus a short note on which Spanish banks are most flexible for your specific profile (residency, currency, deposit size). No agent calls.
2. **Read the buyer guide** at [/buyer-guide-2026.html](/buyer-guide-2026.html) — 32 pages of real €/m² prices by zone, tax structuring, and the closing-process timeline.
3. **Browse properties at your price ceiling** at [/properties](/properties) — we can show you what your actual budget can buy in each Marbella sub-zone, and which trade-offs matter (sea view vs plot size vs urbanisation quality).

When you are ready for a formal mortgage pre-approval, our team can introduce you to two or three Spanish lenders with the strongest current appetite for your profile. There is no fee for that introduction.

## Frequently Asked Questions

**Can a non-resident really get 70% LTV in Spain in 2026?**
Yes, on a clean file. The headline 60-70% non-resident LTV band has held through 2024-2026, and the strongest files (EU passport, transparent income, EUR or GBP, deposit + cost buffer in a Spanish account, no FX exposure) reliably get 70%. US, Russian, Chinese and Middle East buyers more often land at 60% because of FX and source-of-funds friction.

**What rate should I assume — fixed or variable?**
The calculator uses a fixed-rate assumption because Spanish banks have shifted majority-fixed since 2023, and most international buyers prefer fixed for budgeting stability. Variable-rate (Euribor + spread) products do exist and price 0.3-0.6% lower at signing today, but you carry the rate-reset risk every 6 or 12 months.

**Why is my income haircut 10-15% if I earn in USD?**
Spanish bank policy. The bank is exposed to your future income in EUR terms — if USD weakens 15% against EUR over the loan life, your debt-service-to-income ratio breaks the underwriting model. The 10-15% haircut is the buffer they apply at the affordability test. Some banks waive it if you commit to currency-hedge a portion of the loan at signing, or if you can demonstrate diversified EUR-denominated assets covering 18-24 months of payments.

**Does the calculator account for Spanish purchase taxes and fees?**
No — only the affordability ceiling. Plan an additional **11-13% of the property price** on top of the deposit for taxes, notary, registry, lawyer and bank fees. So a €2M purchase needs roughly €2.22M of total committed cash if you want to hit the ceiling. See the "Total costs" section above for the full breakdown.

**Can I refinance later if rates drop?**
Yes. Spanish mortgages can be refinanced (subrogación) with the same lender or moved to a competing lender (subrogación de acreedor), typically with refinance costs of around 1-2% of the new principal. Worth modelling once Euribor moves more than 75-100 bps from your original rate. We can introduce a Marbella mortgage broker for the refinance comparison when the time comes.
