How to Negotiate a Mortgage
Practical tips to negotiate your mortgage and buy the home of your dreams safely

Understand how mortgage credit works in Portugal
Buying a home is one of the biggest financial decisions most people make in life. In Portugal, the majority of buyers rely on mortgage credit to purchase a property, whether it's a permanent residence, a holiday home, or an investment. Understanding how mortgage credit works is crucial to getting the best possible conditions.
The first step is to compare offers from different banks. Each financial institution has its own conditions, and there can be significant differences in terms of interest rates, required guarantees, and associated costs. Consulting a real estate agent with in-depth knowledge of the market and financial tools can be a major advantage. The Engel & Völkers team, for example, has extensive experience in advising buyers at all stages of the process.

FAQ – Frequently Asked Questions About Mortgage Negotiation
Negotiate the interest rate and spread
One of the most important elements of a mortgage is the interest rate, which directly affects the monthly payment. Most mortgages in Portugal are indexed to the Euribor, to which the bank adds its spread — a fixed margin that can be negotiated.
A lower spread can save you thousands of euros over the duration of the loan. When negotiating with banks, consider:
Your financial stability
Your credit history
The value of the down payment (the higher, the better)
Additional products you can subscribe to with the bank
To strengthen your position, try to provide a down payment of at least 20%, which reduces the risk for the bank and often results in more favorable conditions.
Know the associated costs
Many first-time buyers focus solely on the monthly installment, forgetting that buying a house involves several additional costs. When contracting a mortgage, you should account for:
Property appraisal
Process fees
Life and home insurance
Notary and registration fees
To avoid surprises, ask for a full simulation of all costs and carefully read the European Standardised Information Sheet (ESIS) provided by the bank.
Calculate your effort rate
The effort rate is the percentage of your monthly income allocated to paying off the mortgage. Portuguese banks usually recommend that this rate does not exceed 30% to 35%. A higher effort rate may jeopardize your credit approval or result in less favorable conditions.
Use online calculators or ask your bank for simulations considering your income, expenses, and the desired loan amount.
Understand the importance of choosing the right property
It's not enough to have financing approved — choosing the right property is fundamental to ensuring a good investment. Consider the property's location, future appreciation potential, and maintenance needs.
If you are looking for an opportunity in a coastal area, for example, explore houses in regions like Setúbal, Cascais, or the Algarve, which continue to attract both national and international buyers.
The Engel & Völkers property listings include carefully selected properties, often with sea views or located in high-demand areas. With the help of an experienced agent, it's easier to find the ideal house and negotiate the best conditions.
Be prepared to present documentation
To start the process, you must present various documents such as:
Identification and NIF
Proof of income and employment
IRS declaration
Bank statements
Property documentation (if already selected)
While some buyers feel overwhelmed by this phase, working with professionals facilitates the process. An Engel & Völkers real estate consultant can help you gather and verify all necessary documents.
Consider your future financial stability
A mortgage is a long-term commitment, often lasting 30 or more years. Therefore, assess your future ability to pay, possible professional changes, and financial security before committing.
It is also advisable to create a financial reserve to handle unforeseen events and avoid defaulting on payments.
Save money before applying for credit
The greater your financial contribution, the better your chances of getting favorable conditions. If you're not yet ready to apply, start by saving money and controlling expenses.
If you're looking for tips to reach this goal, this practical guide on how to save money to buy a house can be very helpful. Saving consistently and planning ahead will give you more options when choosing the mortgage and the property.
Rely on professionals throughout the process
The mortgage process involves financial, legal, and technical components. Instead of doing everything alone, relying on professionals can speed up the process and ensure better results. A team like Engel & Völkers not only supports in the choice of the property but also in every phase of negotiation and financing.
With the right information and the best partners, buying your dream home in Portugal becomes a more accessible and secure reality.
