Go for it. Your UK 'inFlatable', charges a modest user fee, finds a flat(apartment), renter years later leaves the rental, you return the fee with modest interest(as a model to recast damage fee abuse), and in the meantime, earn on the float, when ex-tenant/user fills their experience on unit/landlord review form, you return the fee with modest interest. Old and new users-renters love your reliable vast database, hilarious scathing reviews, you go viral, and you're on the cover of The Economist and Punch.
