When prices rise faster than rents, yield falls. It is arithmetic, not opinion. In the second quarter of 2026 Portuguese house prices rose 16.5% on a year earlier while rents on new leases rose 10.2%, and both numbers come from the same statistical office.

This article turns those two INE releases into the figure investors actually underwrite: how many years of rent it takes to pay for the property, and what that implies for gross yield and for the mortgage.

Key takeaways: Combining INE's median price (€2,337/m², Q1 2026) with its median new-lease rent (€10.17/m², Q2 2026) gives a national price-to-rent ratio of about 19 years, or a gross yield near 5.2%. Lisbon municipality sits near 25 years and 4.0%. With prices outrunning rents by about six points, the same ratio a year ago implies roughly 5.5% (a rough back-cast).

What is the price-to-rent ratio, and why use it?

It is the purchase price divided by a year of rent. A ratio of 20 means the rent takes twenty years to repay the price. Flip it and you have gross yield: 20 years is 5%, 25 years is 4%.

Investors like it because it ignores financing and tax, and compares markets quickly. Portuguese investors usually quote yield instead, which is the same number upside down. We use both below, because "twenty-five years" feels expensive in a way that "4%" does not.

The ratio is also the cleanest way to see what the market is pricing. Rent reflects what tenants can pay today. Price reflects what buyers expect tomorrow. When the two diverge, the gap is expectation, financing conditions, or both. For the underlying yield definitions, see our rental yield guide and the cap rate explainer.

What did INE report for prices and rents?

On prices, INE's house price index rose 16.5% year on year in the second quarter of 2026, 1.3 points less than the first quarter. Existing dwellings rose 18.0% and new dwellings 12.3%. Quarter on quarter the index rose 3.6%. Some 40,142 dwellings changed hands, 6.4% fewer than a year earlier, for €10.7 billion in total, 4.2% more.

On rents, INE's median for new lease agreements reached €10.17/m² in the same quarter, up 10.2%, accelerating from 9.1% in the first quarter. Grande Lisboa came in at €15.24/m², the Setúbal Peninsula at €11.99, the Algarve at €11.56 and the Porto metropolitan area at €10.83. Lisbon municipality was €17.79, up only 5.1%.

For price levels per square metre we need a second INE release. Its local-house-price statistics for the first quarter of 2026 put the national median at €2,337/m² and Lisbon at €5,292/m², with Cascais at €5,000 and Oeiras at €4,511.

What the two INE series imply for yield

Nationally, a median rent of €10.17/m² a month is €122.04/m² a year. Against €2,337/m² that is 19.1 years of rent, or a gross yield of 5.2%. In Lisbon municipality, €17.79 a month is €213.48 a year against €5,292, which is 24.8 years and a gross yield of 4.0%.

Price €/m²Rent €/m²/monthYears of rentGross yield
Portugal (national median)2,33710.1719.15.2%
Lisbon municipality5,29217.7924.84.0%

Those are approximations, and you should know exactly how rough. The price is a first-quarter median of all sales, the rent a second-quarter median of new contracts, and flats with small floor areas tend to carry a higher rent per square metre than large ones. A different mix of homes would move both figures. Treat the result as a market-level gauge, not as the yield of any listing.

Now the part that is ours. If prices rose 16.5% and rents 10.2%, the rent-to-price ratio was multiplied by 1.102 ÷ 1.165 = 0.946, a 5.4% fall. Run the national 5.2% backwards and the same market a year earlier yielded roughly 5.5%. That is about three tenths of a percentage point of yield lost in twelve months, from nothing but the denominator.

A third reading helps. INE's bank-appraisal series, which reflects what lenders' valuers think properties are worth rather than what buyers paid, stood at €2,254/m² in August 2026, up 14.7% year on year. That is growing a little more slowly than the transaction index and sits below the Q1 transaction median. Valuers are not leading prices upward, and a leveraged buyer should know the bank's valuation before offering, because a valuation below the price may leave the buyer funding the gap.

In short: INE data for 2026 imply a national gross rental yield of about 5.2% (€10.17/m² monthly rent against a €2,337/m² median price) and about 4.0% in Lisbon. Because the house price index rose 16.5% while new-lease rents rose 10.2%, the same market would have yielded roughly 5.5% a year earlier on a rough back-cast.

Does Portuguese rent still cover the mortgage?

Barely, nationally, and not in Lisbon. The ECB's data portal puts the 6-month Euribor monthly average at 2.92% in September 2026, up from 2.10% a year earlier, and the ECB's deposit rate has gone from 2.00% to 2.50% since June. Add an assumed bank spread of 1.2% (our assumption; yours will differ) and a variable mortgage costs about 4.1%.

Set that against gross yields. Lisbon's 4.0% is below the loan rate before any costs. The national 5.2% clears it by about one point, but strip out vacancy, IMI, condominium and maintenance, say 20% of rent as in our other models, and net yield drops to roughly 4.2%. That is almost exactly the cost of the debt. A leveraged purchase at those medians is a bet on price growth, not a cash-flow play.

Does that mean nothing works? No. Medians hide the spread. Our Lisbon yield by parish table shows the range around the average, and some Lisbon-area markets sit well above it. The point is that you now have to find them deliberately rather than buy the average.

Using the ratio as a screening filter

As a filter, in three steps.

  1. Compute the listing's own ratio. Ask price divided by realistic annual rent (a rent you can evidence from comparable lettings, not the agent's hope). Anything above 25 years needs a reason, such as strong appreciation drivers or a low-cost renovation upside.
  2. Compare to the market gauge. If a flat sits at 24 years when its area sits at 19, you are paying a premium for something. Name it.
  3. Test it against your financing. Put the numbers in the cap rate calculator and the rental property calculator, then stress the rate with the fixed versus variable comparison.

Watch the rent side too. The 10.2% figure applies to new contracts; sitting tenants are capped by the annual coefficient, which is 2.56% for 2027 (INE, August 2026 consumer prices). Our rent increase guide shows why that matters for existing landlords. And on the buyer side, foreign buyers paid a notable premium per square metre in the main metro areas (34.5% in Greater Lisbon in Q1, per INE), which pushes the ratio up further in exactly the places international money goes.

The verdict: Portugal is not "overpriced" in a way that guarantees a fall, and the volume figures show buyers pulling back only slightly. But it is a market where yield alone no longer pays for leverage. If you cannot make a deal work at 5% gross, the ratio is telling you to wait for a better entry price or a better rent, not to hope.

Frequently asked questions

What is the price-to-rent ratio in Portugal in 2026?

Combining INE's median price of €2,337/m² (Q1 2026) with its median new-lease rent of €10.17/m² a month (Q2 2026), the national ratio is about 19 years, a gross yield near 5.2%. Lisbon municipality is nearer 25 years and 4.0%.

Are Portuguese house prices rising faster than rents?

Yes. INE reports the house price index up 16.5% year on year in Q2 2026, against 10.2% for the median rent on new leases. Prices outpaced rents by about six points, so gross yield on the same assumptions fell by about 5.4% in relative terms.

Is a gross yield of about 5% enough to cover a mortgage in Portugal?

Barely. With the 6-month Euribor averaging 2.92% in September 2026 (ECB) and an assumed 1.2% spread, a variable loan costs about 4.1%. After operating costs of 20% of rent, a 5.2% gross yield nets to roughly 4.2%.

Why is the yield lower in Lisbon than the national figure?

Lisbon prices are far higher relative to rents. INE's Q1 2026 median price was €5,292/m² against a Q2 median rent of €17.79/m², a ratio of about 25 years and a gross yield of roughly 4.0%, below a typical variable mortgage rate.
