Mid-term rentals in Europe
A finished research run on an example topic, shown in full — the findings, the sources behind them and the product versions are all the run's own output, except that a product name may have been changed where it matched an existing brand.
Product opportunity
Build a cross-platform mid-term rental search and verification layer that flags genuine below-tourist-rate furnished listings for renters relocating across European cities.
- Aggregate listings from Flatio, Wunderflats, HousingAnywhere, Idealista, Airbnb and Vrbo monthly sections into one searchable index
- Compute a local-rent benchmark per city and flag listings priced 3-5x above it as likely relabeled short-term inventory
- Let renters filter by verified lease terms, deposit rules and minimum stay across multiple cities in a single itinerary
- Surface expat-group and agency listings currently shared informally on Facebook and Reddit into the same searchable feed
Rationale
Renters are already improvising across fragmented, unverified channels while genuine demand and abusive relabeled supply are mixed in the same listings, creating a clear information gap.
No existing platform combines cross-site aggregation with price-legitimacy scoring, despite several city-limited competitors already proving demand for furnished 30+ day stays.

Experimental
ArbitrageWatch
A regulatory-compliance and transparency tool that identifies which 'mid-term' listings are recently converted short-term-rental units created purely to dodge tourist-rental crackdowns, using permit and registration data cross-referenced with listing history.
Open ideaTrend & recent change
Mid-term rentals in Europe are shifting from a travel-search niche into a regulatory-arbitrage and asset-class story: scholarship now frames the segment as a deliberate escape route from short-term-rental crackdowns, landlords and institutional investors are reclassifying stock as 'mid-term' to dodge tourist-rental rules, and a small wave of new platforms and property-management tools is emerging to serve this specific 30+-day furnished-stay market, even though direct search interest for the category itself remains negligible.
Mid-term rentals as regulatory evasion
Academic work now explicitly frames mid-term rentals as a regulatory workaround rather than an organic housing segment, describing 'regulatory evasion' and new tenant profiles emerging as landlords convert short-term listings to mid-term to sidestep tourist-rental restrictions.
Evidence
A 2026 paper titled 'The mid-term rental turn: Between regulatory evasion, asset liquidity and new tenant profiles' and a companion piece on Barcelona's mid-term rental rise both treat the mid-term format as a strategic response to short-term-rental regulation rather than natural demand growth.

Institutional financialization of rentals
Research is tying mid-term and short-term rental growth to financialization, with institutional investors and asset managers consolidating rental stock into a distinct investable class in cities like Barcelona.
Evidence
Studies on 'the financialisation of short-term rentals in Barcelona' and 'institutional investment in rental housing in the city of social housing' describe property ownership consolidating around this asset class.

User problems surfaced
No trusted mid-term search hub
Renters seeking 1-3 month stays across Europe find that dedicated mid-term platforms are inconsistent or unknown outside a few countries, so they resort to Idealista, local agencies and Facebook expat groups instead of a single reliable marketplace.
Evidence
Multiple digital-nomad forum threads ask what to use besides Airbnb for 1-2 month EU stays, and answers point to a patchwork of local rental agencies, Facebook expat groups, and country-specific sites like Idealista rather than one consistent solution.

Mid-term listings priced like tourist rentals
Travelers report that outside of a few markets, monthly-rate listings are priced 3-5x higher than ordinary local monthly rents because they are really short-term (tourist) inventory relabeled, not genuine mid-term stock.
Evidence
A renter states Idealista is the only site with reasonable prices while Airbnb-style listings run 3-5x monthly local rates throughout Spain and Italy; another thread notes landlords hoped regulation would push €4k/month condos down but it didn't.
