Aggregator
A site that collects live listings from many fractional real estate platforms into one list with the same fields, so properties can be compared across platforms without visiting each one.

What it is
An aggregator reads the listings each fractional real estate platform publishes, stores them, and shows them together in one place, the way a flight search shows every airline's fares on one screen. Each listing keeps a link back to the platform where the purchase happens, and the aggregator itself sells nothing and holds no money. The value is in the columns. Platforms quote yield, price and minimums in different currencies and on different bases, and an aggregator rewrites all of them into one set of fields so that a sort by yield or a filter by country means the same thing for every row. Threeworld is the aggregator behind this glossary, and the guide to fractional real estate aggregators compares it with the review directories and platform lists that cover platforms rather than listings.
How it works
An adapter per platform visits that platform's public pages or feed on a schedule, usually daily, and records every listing it finds: price per share, projected yield, funding progress, status, property type, city and country, and the documents attached. A normalisation step converts prices to one currency, labels each yield as a cash figure or a projection, and marks listings open, funded, sold out or closed as they move. Many aggregators then add their own layer, such as a score against peers, a market-wide index or a note on the platform's own health. What an aggregator cannot do is verify a projection. The yield on a listing is the platform's claim, carried across as published, so the aggregator's job is to label it and put it next to its peers, not to vouch for it.
What to check
Four things tell you whether an aggregator is worth trusting. Whether it shows live listings at all, or only reviews of platforms. When each listing was last refreshed, because a stale open listing is worse than no listing. Whether it says which platforms it covers and which it does not, so that absence means not covered rather than not available. And whether it flags platforms in trouble, since a platform in liquidation can keep its listings online long after the rent has stopped. Then check the business model. An aggregator paid by platforms for sign-ups has a reason to rank them generously. One that sells a subscription or tools to investors has a reason to be accurate. Either is legitimate as long as it is stated.
