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.
What to build
MVP
A dashboard for a handful of regulation-heavy cities (Barcelona, Amsterdam, Lisbon) matching public short-term-rental permit registries against listings that recently switched to 30+ day minimum stays, flagging suspicious conversions.
Why it can be better
Coverage now frames mid-term rentals explicitly as a regulatory-evasion vehicle, but renters currently have no way to tell genuine mid-term stock from relabeled tourist units created to dodge crackdowns; this exposes that distinction directly.
Revenue model
B2B subscription sold to city housing authorities, journalists and tenant-rights organizations tracking regulatory evasion, plus a consumer-facing free tier for basic flags.
Target user
Municipal housing regulators, tenant advocacy groups and investigative journalists tracking short-term-rental crackdown evasion.
Context
The opportunity this answers
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.
Why now
Regulatory crackdowns on short-term rentals across European cities are actively pushing landlords and institutional investors to relabel stock as mid-term, creating a fast-growing but unverified supply just as dedicated platforms like Flatio, Wunderflats and HousingAnywhere are scaling city coverage, meaning the market has enough real inventory and enough abusive relabeling happening simultaneously that a verification and aggregation layer is now buildable and needed, whereas a year or two ago the segment was too thin to support it.
