Key figures — as of 2026-10-01: National average rent €1,300/month in September, flat versus August and versus September 2025 — North up 26.7% year-on-year (€750 → €950) — South up 17.6% (€850 → €1,000) — Centre, including Lisbon, up just 0.6% to €780, with Lisbon itself down 3.7% (€1,750 → €1,685).
One national number hides two very different markets
A flat national average is the kind of headline that tells you almost nothing useful if you're actually trying to rent a flat in Portugal this autumn. The average rental price was €1,300 in September, meaning it did not change compared to August or the same month last year, according to Imovirtual's monthly barometer. But between regions the trend is quite different — in the North, average rent rose 26.7% (from €750 to €950 monthly), while the South saw a 17.6% increase (from €850 to €1,000). In the Centre, including Lisbon, the rise went no further than 0.6%, reaching €780 monthly.
For anyone relocating, that gap matters more than the national figure ever will. A tenant signing a lease in the North this month is paying meaningfully more than the person who signed a year ago — while someone eyeing the capital is, oddly, catching a small break.
Where it's getting expensive — and why
Viana do Castelo registered a 26.7% annual increase in rent, from €750 to €950 a month, while Porto held at €1,200 (up 9.1% year-on-year) and Braga reached €950, an increase of 6.7%. That's the North in miniature: smaller, previously cheap cities and towns catching up fast to the better-known urban centres, likely driven by remote workers and buyers priced out of Lisbon and Porto proper pushing further out.
The South tells a similar story at a slightly gentler pace, with the region's rents climbing 17.6% as demand spreads into the Algarve hinterland and Alentejo towns that used to be afterthoughts on a relocation shortlist.
Where it's actually getting cheaper
Lisbon is the surprise. Lisbon continues to show the highest average rent in the region, at €1,685 a month, but recorded a 3.7% drop compared with €1,750 in September 2025. Coimbra moved even further in that direction: rents there fell 9.4 percent, from €800 to €725. Imovirtual's own marketing manager, Sylvia Bozzo, framed the pattern plainly, saying the differences between regions underline the importance of looking further than national averages because some areas keep climbing while others stabilise or fall.
Sale prices moved in roughly the same stable-on-the-surface way: the national average purchase price stood at €430,500, practically in line with the €430,000 recorded in August and in September of last year.
GrowIN's take: what the gap actually costs
Run the numbers and the regional split isn't abstract — it's a real monthly budget difference for anyone choosing where in Portugal to live. A renter who moved to Viana do Castelo or a comparable North Portugal town a year ago and is renewing now faces roughly €200 more a month than the old €750 baseline — close to €2,400 a year in extra housing cost, on a market that was marketed as Portugal's "affordable alternative" to Lisbon as recently as 2025. Meanwhile, someone choosing Lisbon over Porto this September pays about €485 more a month (€1,685 vs. €1,200) but is, unusually, negotiating from a market that's easing rather than tightening.
"The 'cheap North' pitch to foreign renters is ageing fast — the real bargains this quarter are in the capital, not away from it," says GrowIN Portugal Editorial.
Practical implications for foreigners
If you're house-hunting with a D7, D8 or Golden Visa fund application in progress, don't assume the smaller northern city you scoped out last year is still the deal it was — Braga, Viana do Castelo and similar towns have closed much of the gap with Porto. Conversely, Lisbon and Coimbra are worth a second look if your work lets you be mobile; both are now moving against the national grain. Budget planning for a move should always separate the IMT, stamp duty and notary costs of buying (see our relocation hub for the full sequence) from the simple monthly cost of renting while you get settled — the two markets are no longer moving together, and this barometer shows exactly where they've diverged.
What to watch next
Imovirtual publishes its barometer monthly, so October's edition will show whether the North's 26.7% surge is a plateau or still climbing, and whether Lisbon's decline holds or reverses once the usual autumn demand from new arrivals picks up. Anyone relying on last year's "best value region" lists should treat them as provisional until that next release lands.
