Olsztyn property market guide: prices, rents and yields in 2026

Apartments in Olsztyn, the capital of the Warmińsko-Mazurskie voivodeship, had an average asking price of €2,275.6/m² in Q3 2026 according to CASAFARI Area Insights (asking prices from indexed listings, not transaction prices), up 13.2% on Q3 2025. Average asking rents reached €12.8/m² per month, giving an indicative gross yield of about 6.7%, though price growth has slowed to +0.5% quarter on quarter, any nationality can buy a flat here without a permit, and new-build transaction prices run well below asking.

Imagine a buyer who has watched Poland's coastal and capital markets climb out of reach. Opening a property portal to look at Olsztyn, they find a 48 m² two-room flat in the southern estate of Jaroty advertised at roughly €109,000. Two questions immediately follow: is that asking figure what buyers actually sign for at the notary, and what will the flat realistically rent for once the autumn semester begins at the university?

What does an apartment in Olsztyn cost in 2026?

According to Area Insights, CASAFARI's price and rent series by location (location id 6305611), the average asking price for an apartment in Olsztyn stood at €2,275.6/m² in Q3 2026. That represents a 13.2% increase on Q3 2025 (€2,010.6/m²) and a 22.6% rise since Q2 2025 (€1,856.4/m²), which is the first quarter with full listing coverage in our series. All CASAFARI figures represent asking prices from indexed property listings, with statistical outliers excluded, converted into euro.

At the Q3 2026 average of €2,275.6/m², a typical 48 m² two-room flat carries an asking price of roughly €109,200. That leaves Olsztyn among the most accessible regional capitals in the country, sitting well below the levels recorded in the Gdańsk area guide and the Warsaw area guide.

The trajectory of the curve matters as much as the headline figure. After a rapid catch-up in the second half of 2025, quarterly asking-price growth decelerated steadily through 2026: +4.1% quarter on quarter in Q1 (€2,226.4/m²), +1.7% in Q2 (€2,263.6/m²), and +0.5% in Q3 (€2,275.6/m²). Because local sellers price their properties in Polish złoty, part of the euro-denominated movement reflects PLN/EUR exchange-rate fluctuations alongside local market dynamics.

Our chart and trend analysis begin in Q2 2025 because earlier quarters in the database repeat a single figure (€1,729.4/m² from Q1 2023 to Q1 2025 for sales, and €9.9/m² from Q1 2024 to Q1 2025 for rents), which indicates sparse data coverage at the time rather than a flat market.

Where do buyers look in Olsztyn, and why do the lakes matter?

Olsztyn is a mid-sized regional capital with 165,393 registered residents at 31 December 2025, according to the Statistical Office in Olsztyn (in Polish). Unlike industrial cities of a similar scale, its geography is defined by the Łyna river valley, municipal forests, and lakes inside the city limits—among them Ukiel, Długie, Kortowskie and Track—with the Kortowo campus of the University of Warmia and Mazury (UWM) sitting directly on the shore of Lake Kortowskie.

That geography splits the residential market into distinct segments:

• Lake-side and north-western districts (Likusy, Redykajny, Dajtki, Gutkowo): These neighbourhoods near Lake Ukiel and the northern forests command the city's highest asking prices and attract domestic households trading up to newer low-rise blocks or terraced homes.
• Śródmieście (City Centre): Sought after for renovated pre-war tenements (kamienice) and proximity to public administration, courts and cultural institutions.
• Southern and eastern block estates (Jaroty, Nagórki, Pieczewo, Zatorze): Large housing estates built between the 1970s and 1990s. They account for the bulk of secondary-market turnover and attract small investors buying flats for student lets, given the direct bus and tram links from Nagórki and Jaroty to Kortowo.
• Southern edge and neighbouring municipalities (Stawiguda, Dywity, Barczewo): Much of the new-build development pipeline has spilled just across the city boundary into adjoining gminy (municipalities), which compete directly with outer Olsztyn districts for young families.

Notably, there is no meaningful holiday-home market inside the city limits. Buyers seeking a second home in the region normally look 50 to 100 kilometres east toward the Great Masurian Lakes around Mrągowo, Giżycko and Mikołajki. Olsztyn itself functions as a year-round primary-residence and university market, connected to Warsaw and Gdańsk by rail and the S7/S51 expressway corridor, with the regional Olsztyn-Mazury airport at Szymany roughly 55 kilometres to the south-east.

What do apartments rent for, and what yield can an investor expect?

In Q3 2026, the average asking rent for an apartment in Olsztyn reached €12.8/m² per month according to CASAFARI Area Insights, up 6.7% on Q3 2025 (€12.0/m²) and 23.1% since Q2 2025 (€10.4/m²). At that rate, a standard 48 m² two-room apartment is advertised at roughly €614 per month before administrative service charges.

Comparing average asking rents with average asking sale prices gives an indicative gross rental yield of 6.7% in Q3 2026 (calculated as 12 × €12.8 ÷ €2,275.6). Across the six usable quarters in the CASAFARI series, this indicative gross yield has stayed in a narrow band because rents and sale prices rose in tandem: 6.7% in Q2 2025, 7.2% in Q3 2025, 6.7% in Q4 2025, 6.5% in Q1 and Q2 2026, and 6.7% in Q3 2026.

We call this an indicative gross yield because it divides asking rent by asking price. Actual net returns for a private landlord will be lower once you deduct Polish rental income tax, void periods between academic years, maintenance, and the monthly administrative fee (czynsz administracyjny) paid to the housing cooperative or community if not passed on in full to the tenant.

Tenant demand rests on three pillars: the student body at UWM in Kortowo, young employees in the public administration and regional hospital system, and Ukrainian families who have settled in the city since 2022. Demand concentrates heavily on compact one- and two-room apartments. You can compare these dynamics with other regional hubs using CASAFARI tools for property investors and our broader overview in our guide to the Polish property market.

Is the rise real? Asking prices against GUS and NBP data

When evaluating any Polish city, it helps to set portal asking prices alongside official transaction registries. In Poland, two public institutions publish benchmark housing statistics: Statistics Poland (GUS, Główny Urząd Statystyczny), which compiles official price indices from notarial deeds recorded in the public Register of Property Prices (RCN), and the National Bank of Poland (NBP, Narodowy Bank Polski), which tracks asking and transaction prices across regional capitals in Narodowy Bank Polski's housing market reports.

If we compare the latest quarter where both official and CASAFARI series are published—Q2 2026—the quarterly momentum aligns closely. CASAFARI Area Insights recorded apartment asking prices in Olsztyn rising +1.7% quarter on quarter in Q2 2026. Over the same quarter, GUS price change indices by voivodeship, Q2 2026 (in Polish) measured transaction prices across the Warmińsko-Mazurskie voivodeship at +1.7% quarter on quarter (index 101.7), while Statistics Poland's price indices of residential premises for Q2 2026 put the national Polish average at +1.5% quarter on quarter and +6.3% year on year (+6.5% on the primary market and +6.1% on the secondary market).

Metric / Source	Scope	Basis	Q2 2026 (q/q)	Annual change
CASAFARI Area Insights	Olsztyn city (apartments)	Asking prices (listings, EUR)	+1.7%	+13.2% (Q3 2026 y/y)
GUS Voivodeship Index	Warmińsko-Mazurskie	Transaction deeds (PLN)	+1.7%	Not published at voivodeship level
GUS National Index	Poland (whole country)	Transaction deeds (PLN)	+1.5%	+6.3% (Q2 2026 y/y)

Where buyers must be careful is the gap between developer asking prices and closed deeds. According to portal analysis of asking versus transaction prices for new builds in Olsztyn (in Polish) drawing on Register of Property Prices data for Q1 2026, primary-market listings averaged PLN 12,442/m² while the 57 recorded primary-market transactions averaged PLN 9,545/m²—a 23.3% gap, the widest among the 12 Polish cities analysed. That divergence occurs both because developers discount during negotiations and because buyers disproportionately select the more affordable units in a scheme while expensive lakeside penthouses sit on portals for months.

Because a city of 165,000 records only a few hundred transactions per quarter, small samples can skew district averages. Rather than relying on headline portal rates, buyers should value a specific flat with Comparables and a market study and review wider property market trends across CASAFARI's markets.

Can a foreigner buy in Olsztyn, and what will the purchase cost?

Poland's rules on foreign ownership distinguish sharply between self-contained apartments and land. Under the Act of 24 March 1920 on the acquisition of real estate by foreigners, as summarised in official guidance on property purchases by foreigners (in Polish), a foreigner of any nationality may buy a self-contained residential apartment (samodzielny lokal mieszkalny) without obtaining a permit from the Ministry of the Interior and Administration (MSWiA).

Citizens and businesses of the European Economic Area (EEA) and Switzerland can also buy houses and plots of land without a permit. Buyers from outside the EEA and Switzerland require an MSWiA permit (carrying an administrative fee of PLN 1,570) if they wish to purchase a house with land, an undeveloped plot, or any property located in Poland's statutory border zone. Although the northern counties of the Warmińsko-Mazurskie voivodeship border the Kaliningrad oblast, the city of Olsztyn itself does not lie inside the border zone, so the apartment exemption applies in full.

Transaction taxes depend on whether you buy an existing flat or a new build from a developer, as detailed in the Act on tax on civil-law transactions explainer (in Polish):

• Secondary market (existing flats): Purchases are subject to the tax on civil-law transactions (PCC, podatek od czynności cywilnoprawnych) at 2% of the property's market value, collected and remitted by the notary at signing. Since 31 August 2023, a natural person buying their very first residential property is exempt from the 2% PCC.
• Primary market (new builds from a developer): Sales are exempt from normal PCC because the developer's price already includes Value Added Tax (VAT), charged at 8% on floor area up to 150 m² and 23% on any portion above 150 m². However, since 1 January 2024, buyers purchasing a sixth or further apartment within the same development on VAT are subject to an additional 6% PCC.
• Additional closing costs: Buyers pay the notary's fee (taksa notarialna, capped by statutory scale), court fees to update the land and mortgage register (księga wieczysta), and any negotiated agency commission.

A Polish national identification number (PESEL) is not legally required to sign a purchase deed, though foreign landlords usually obtain one for tax administration.

What are the risks: a shrinking city, ample supply and a slowing market

A clear-eyed assessment of Olsztyn requires looking beyond the 6.7% indicative gross yield to the structural constraints of the local economy:

1. Demographic contraction: According to data from GUS Bank Danych Lokalnych published via the Statistical Office in Olsztyn (in Polish), Olsztyn's registered population stood at 165,393 at the end of 2025, down by 5,313 residents (−3.1%) since 2020 and well below its 2009 peak of 176,457. The wider Warmińsko-Mazurskie voivodeship also declined to 1,339.5 thousand residents at December 2025. Long-term housing demand inside the city therefore relies on university enrolment, regional service employment and households trading up from older blocks rather than organic population growth.
2. Suburban competition and slowing momentum: Quarterly asking-price growth in Olsztyn slowed from +4.1% in Q1 2026 to +0.5% in Q3 2026. With an active development pipeline on the southern edge of the city and in adjacent municipalities, a flat-to-soft price environment in 2027 is plausible.
3. Primary-market overpricing: With portal asking prices on new builds sitting 23.3% above closed RCN transaction averages in Q1 2026, buyers who pay sticker price risk overpaying relative to the local market.
4. Currency exposure: For an investor accounting in euro or sterling, both the capital value of the flat and the monthly rental stream are denominated in Polish złoty.
5. Short data history: Because CASAFARI's dense listing coverage in Olsztyn begins in Q2 2025, year-on-year comparisons are only meaningful from Q2 2026 onwards.

How to check Olsztyn prices yourself with CASAFARI

Before making an offer or advising a client on an Olsztyn property, you can verify both the city-wide trend and the building-level comparables directly in our software.

In Area Insights, CASAFARI's price and rent series by location, selecting Olsztyn (location id 6305611) and the Apartments segment displays the exact quarterly sale and rental curves cited in this guide, allowing you to track whether the Q3 2026 plateau (+0.5% q/q) turns into a broader repricing.

When you have a specific listing in hand—say, a two-room flat in Nagórki or a newer apartment near Lake Ukiel—the practical way to handle the gap between asking and transaction prices is to value a specific flat with Comparables and a market study. Comparables deduplicates listings across Polish portals, shows how long competing flats in the same street have been on the market, and reveals any price reductions made by sellers.

For proptech teams, quantitative analysts and institutional advisers building their own models, Location Lookup resolves Olsztyn to location id 6305611, which can be passed directly to the Area Insights API documentation or the Comparables and valuation API documentation.
