Buying a Spanish property is exciting, but banks need to check if you can afford the repayments before you get a loan. This is called a mortgage affordability test in Spain. It helps Spanish lenders see if you can manage your monthly mortgage payment without financial strain.
If you’re planning a property purchase, your financial situation matters. The test determines your monthly income, debts, and expenses to determine your maximum loan amount. Understanding this process will help you prepare better and improve your chances of getting a Spanish mortgage.
How do Spanish banks check mortgage affordability?
When you apply for a mortgage product, the bank runs several checks to see if you can repay the loan. These checks include:
1. Income assessment and proof of income
Banks must see how much you earn to ensure you can afford your monthly payments. They will ask for:
- Payslips or employment contracts (for salaried workers)
- Tax returns (for self-employed)
- Rental incomes (if you earn money from properties)
- Bank statements showing your income stability
Your disposable income plays a key role in this assessment. A steady income improves your chances of getting a mortgage contract.
2. Debt-to-income ratio: How much debt do you have?
The debt-to-income ratio (DTI) compares your earnings to your debts. Spanish banks prefer that your total debts, including the new loan term, do not go over 35% of your monthly income.
They will check you:
- Credit score and credit report
- Existing loans (car loans, personal loans, student debt)
- Credit card payments
Having a low DTI ratio shows that you can manage a new loan.
3. Loan-to-value ratio: How much deposit do you need?
The loan-to-value ratio (LTV) is the percentage of the property’s price that the bank will lend.
- Fiscal residents in Spain can get up to 80% LTV.
- Non-residents may get a maximum loan of 70% LTV.
If you’re a non-resident, this means you must pay a larger deposit, typically 30% of the property price.

How mortgage interest rates affect affordability
When you take a Spanish mortgage, the type of interest rate you choose will affect your monthly mortgage payment. The higher the interest rate, the more you pay each month. Choosing the right mortgage type depends on whether you prefer stable payments or are willing to take risks for lower costs.
1. Fixed-rate mortgages: Predictable payments
With a fixed-rate mortgage, your interest rate stays the same for the entire mortgage term. This means your monthly payments never change, no matter what happens in the Spanish mortgage market.
Example:
Emma buys a Spanish property with a fixed-rate mortgage at 3% interest for 20 years. Even if interest rates increase to 5% or drop to 2%, she will still pay the same monthly amount. This option is great if you like knowing exactly how much you will pay each month.
2. Variable-rate mortgages: Changing payments
A variable mortgage has an interest rate that fluctuates based on market conditions. If interest rates rise, your monthly payments increase. If rates drop, your monthly payments decrease.
Example:
David takes out a variable-rate mortgage. When he first buys his investment property, his rate is 2.5%, and his monthly mortgage payment is €800. A year later, the rate increased to 4%, and his new payment was €1,000. If rates drop again, his payments will decrease, too. This type of mortgage works best for people who can handle payment changes.
3. Mixed mortgage options: A combination of both
Some Spanish lenders offer mixed mortgages, in which the interest rate is fixed for the first few years and then switches to a variable rate. This gives you stability at the start and flexibility later.
Example:
Laura gets a mixed mortgage with a fixed rate of 3% for the first 5 years. During this time, her monthly payments stay the same. After 5 years, the mortgage switches to a variable interest rate. If market rates are lower at that time, she could end up paying less.
Which mortgage type is best?
- Choose a fixed-rate mortgage if you want stable payments and don’t like surprises.
- A variable mortgage might suit you if you don’t mind risk and want lower rates when possible.
- A mixed mortgage option could be a good choice if you want both stability and flexibility.
Choosing the right mortgage depends on your financial situation and how comfortable you are with changes in your monthly payments.
Using a borrowing power calculator for mortgage affordability
A Spanish mortgage calculator helps estimate how much you can borrow based on:
- Income assessment
- Expenses and debt levels
- Mortgage interest rates
Many Spanish mortgage calculators let you check your maximum loan and compare different mortgage options. Before applying, these tools give you a rough idea of your home financing eligibility.
Costs that Affect Your Mortgage Affordability
It’s not just the loan you must consider when taking a mortgage. Other costs include:
1. Stamp duty and arrangement fee
Spain charges stamp duty on property purchases, which varies by region. You’ll also pay an arrangement fee to set up the mortgage.
2. Capital repayment and repayment penalties
Some banks charge repayment penalties if you clear your loan early. It’s good to check your mortgage contract to avoid surprises.
3. Life insurance and other additional costs
Some banks may require life insurance to cover your mortgage in case of unexpected events. You should also budget for construction costs if you plan to build.
How mortgage brokers and financial institutions help
Mortgage brokers can guide you through buying and help you find the best deal. They work with financial institutions to match you with lenders who suit your financial situation.
Getting a mortgage in Spain can feel overwhelming, especially with different lenders offering various options. This is where looking for a reliable mortgage broker can make a difference.
They also explain the mortgage process and help you prepare documents like:

- Credit report
Final steps before applying for a Spanish mortgage

- Check current mortgage rates – Compare deals from different banks.

Understanding the Spanish mortgage market and preparing well increases your chances of getting the best mortgage options.

Frequently Asked Questions
What happens if my mortgage application is rejected in Spain?
If your mortgage is rejected, it’s usually due to low income, high debt, or a poor credit score. You can improve your chances by increasing your disposable income, reducing debts, and ensuring you have the right paperwork. Consulting a mortgage broker may help you find better options.
Can I get a mortgage in Spain without being a fiscal resident?
Yes, non-residents can apply for a mortgage, but they often need a larger deposit (at least 30% of the property price). They also pay higher mortgage interest rates and must provide extra documents like proof of Spanish income tax payments and international bank-to-bank transactions.
