Urby is a platform for investing in one specific house at a time. Each share is a Profit-Share Contract tied to a single landed property. It entitles you to a portion of the profit when that house is sold. It does not make you an owner or a landlord: you carry none of the upkeep, and it gives no right to live there.
That is a different structure from a REIT, which spreads you across a market, and from the special purpose vehicle most fractional platforms use, where investors also inherit the property's management. On Urby the listing partner buys, restores and manages the house. You participate in the appreciation.
Urby earns fees on transactions: new listings and trades on its secondary market. Terms are in the FAQ.
