Rental price cap extended — what it means for landlords across Austria

Austria's rental market is entering a new era. The Mietpreisbremse (rent brake), described by government officials as the most significant rental reform in decades, takes effect in 2026 with sweeping changes that directly impact landlord returns and investment strategies across the country.

The headline numbers: for regulated-sector properties (Altbau and municipal housing), rent increases are capped at just 1% in 2026, rising to 2% in 2027. For free-market rentals, landlords can only pass on a portion of inflation above 3%. If inflation hits 4%, the maximum rent increase is 3.5%. At 5% inflation, the cap is 4%.

Perhaps more significant than the price caps is the lease term change. From January 2026, the minimum rental contract duration rises from three years to five years — applying to both new agreements and extensions. The only exception: small private landlords who are not classified as "entrepreneurs" under Austrian consumer protection law may still offer three-year contracts.

For buy-to-let investors, the math changes significantly. A landlord who purchased a Vienna apartment at €350,000 with an expected annual rent increase of 4–5% must now recalculate with 1–2% increases in the near term. Over a five-year hold period, cumulative rental income could be 8–12% lower than pre-reform projections.

The five-year minimum lease term adds another constraint. Landlords can no longer use shorter contracts to regularly adjust rents to market rates. This particularly affects investors in high-demand inner districts where turnover between tenants was a key mechanism for capturing rising rents.

However, the reform doesn't apply uniformly. New-build properties (first occupancy) remain exempt from the regulated-sector caps, creating a clear incentive for investors to focus on new construction. This is already visible in the data: pre-sale interest for new-build apartments in Vienna rose 15% in the quarter following the reform announcement.

Vienna's rental market data shows the current landscape. Average asking rents sit at approximately €14.20/m²/month, with yields averaging 4.8% gross city-wide. Inner districts yield 2.5–3%, while outer districts like Favoriten and Floridsdorf offer 4.3–5.5%. The reform compresses future yield growth but doesn't eliminate the income stream.

For tenants, the reform provides welcome stability. In a city where approximately 75% of residents rent their homes, protection from sharp rent increases has broad political support. The trade-off: reduced landlord returns may slow the supply of new rental housing if investors redirect capital elsewhere.

The bottom line for investors: the Mietpreisbremse changes the rules but doesn't close the market. New-build exemptions, outer-district yields, and Vienna's structural housing demand all support continued investment. The strategy shift is clear: focus on new construction, target higher-yield districts, and extend your hold-period assumptions.
