Key point
Higher interest rates matter to a property sale because they can change what a buyer can afford. They do not automatically change every mortgage payment or determine the price of a home. For a buyer, the next step is an up-to-date financing proposal. For a seller, it is a clear picture of the buyer's funding, outstanding checks and proposed timetable.
What the ECB decided in September 2026
On 10 September, the European Central Bank raised its three key rates by 0.25 percentage points. From 16 September, the deposit rate is 2.50%, the main refinancing rate 2.65% and the marginal lending rate 2.90%. These are central-bank rates, not mortgage offers to households.
Will your existing mortgage payment change?
Check the rate type and review date in your agreement before changing your budget. Ask the bank for the next payment calculation using your outstanding balance and remaining term.
- Variable rate: typically Euribor plus a spread, reviewed at the contractual interval using the applicable monthly average.
- Fixed rate: the agreed interest rate stays unchanged for the fixed period.
- Mixed rate: check when the fixed period ends and which variable-rate terms follow.
Why a 0.25-point ECB rise is not a 0.25-point mortgage increase
Policy decisions influence financing conditions, but their effect reaches borrowers through different contracts and at different times. Existing fixed-rate loans and loans approaching a reset therefore need separate analysis. A headline cannot replace the rate calculation in your contract.
Illustrative calculation, not a bank offer: with €200,000 outstanding, 30 years remaining and equal monthly principal-and-interest payments, an annual nominal rate of 3.50% gives about €898.09 a month. At 3.75%, the same calculation gives €926.23: approximately €28.14 more each month.
This example divides the annual nominal rate by 12 and assumes 360 monthly payments. It excludes insurance, fees and other costs. It shows what a change in the mortgage's own rate would mean under those assumptions; it does not assume that the ECB decision produces that exact change.
Buying a home: update the finance before making a commitment
Ask for a current FINE, the standard mortgage information sheet, and compare the proposed amount, term, rate structure, payment, TAEG and total amount payable. Banco de Portugal distinguishes the FINE supplied with a simulation from the new FINE issued when a loan is approved. A simulation alone is not an approval.
Build your purchase budget around the whole transaction. Keep the deposit, purchase costs, moving expenses and a cash reserve separate from the monthly payment. If a mixed-rate offer looks attractive, request a calculation for the period after the initial fixed rate as well.
Before agreeing a completion date, ask which steps remain: borrower assessment, property valuation, documents or final approval. If your purchase depends on finance, have the relevant condition and its deadlines reviewed by the professional advising on the CPCV. Do not assume an informal conversation with a bank protects a deposit.
Selling property: compare the funding and conditions behind each offer
Higher financing costs can make some buyers more sensitive to price and monthly outgoings. That is a possible effect, not evidence that your property must be discounted. Ask your estate agent for local comparables, recurring viewing feedback and the actual conditions attached to offers.
An offer with a higher price can still require more time or leave more financing questions unresolved. Compare the offers side by side without collecting unnecessary private financial documents yourself. The lender assesses the borrower's finances; the sale needs clarity about the steps and conditions.
- Is the buyer using a mortgage, own funds or proceeds from another sale?
- Which financing and property checks are complete, and which are outstanding?
- What timetable is proposed for valuation, approval, CPCV and completion?
- What happens if the agreed financing condition is not met on time?
What to ask a real estate agency in Portugal
Ask the agency to connect the market news with your sale: what evidence supports the asking price, how buyer feedback will be recorded and how offers and deadlines will reach you. A forecast about interest rates is not a substitute for an organised sale process.
For an online estate-agency service, confirm who supplies photographs, hosts viewings and follows up enquiries. IMOJA Online Sale costs €499 including VAT for one property and 90 days from first publication. The owner provides photographs and hosts viewings; IMOJA prepares and publishes the listing, responds to enquiries and passes on offers within the agreed scope. The fee pays for the service even if the property does not sell.
If you need photography, viewings or more support around completion, compare the scope of the other selling options. Financing approval belongs to the lender, and legal review belongs to the qualified professional appointed for the transaction.
Should you buy or sell now?
The ECB decision alone cannot answer that question. A buyer should compare an affordable purchase now with the cost and uncertainty of waiting. A seller should compare a realistic net sale result with the ongoing cost of keeping the property.
If you are selling one home to buy another, assess both sides together. Write down the available cash, realistic dates and what happens if one transaction takes longer. A workable plan matters more than trying to guess the next rate decision.
