About iomproperties.im
An independent search over every Isle of Man estate agent's listings, joined to the Isle of Man Government's own public property and planning registers. Not an agent, not owned by one, and not paid to rank anybody — the site earns nothing from where a property appears in its results.
iomproperties.im is owned and operated by 37x Limited (Guernsey company CMP76157). No estate agent, developer or professional firm holds any stake in it or pays for placement on it. Contact details.
Where each number comes from
| What you see | Source | Refreshed |
|---|---|---|
| Listings, prices, photos | Each agent's own public website (10 agents) | Daily, 03:10 UTC |
| Sold prices | Isle of Man Land Registry transaction report — the Government's own bulk file, Open Government Licence | Monthly, 3rd at 02:20 UTC — the Registry republishes monthly |
| Planning applications and appeals | Planning and Building Control / DEFA open data, 24 annual CSVs, Open Government Licence | Monthly, 5th at 02:40 UTC — but DEFA publishes annually, so this currently runs to 2023 |
| Stock levels & asking-price changes | This site's own observations | Daily, 04:10 UTC — the history starts from 22 Aug 2026 |
| House price index | Computed here from repeat sales in the register | With the register |
What each dataset is licensed for
Every row below was checked against the source rather than assumed, and the answer is not uniform. Where a source publishes no licence terms, this table says Unknown — not "probably fine". Access is not a licence, and a government publishing something is not the same as a government licensing it for reuse.
| Dataset | Records | Licence | Commercial use | Derivatives |
|---|---|---|---|---|
| Sold prices — Land Registry transaction register gov.im states "All content is available under the Open Government Licence" on the dataset page. The OGL grants commercial exploitation and adaptation, conditional on attribution. | 43,070 | Isle of Man OGL | Yes | Yes |
| Planning applications — PABC / DEFA open data Same statement on the open-data page, with no stated exception. | 17,561 | Isle of Man OGL | Yes | Yes |
| Planning appeals — PABC / DEFA open data Published alongside the applications files, under the same statement. | 1,284 | Isle of Man OGL | Yes | Yes |
| Protected Buildings Register Published on pabc.gov.im, which carries no licence statement — unlike gov.im. Reproduced here from the public register as Crown copyright. This site claims no reuse right over it and its structured data carries no licence field. | 326 | Unknown | Unknown | Unknown |
| Points of interest — OpenStreetMap Open Database Licence: commercial use and adaptation permitted, but share-alike and attribution are required of anyone reusing it onward. | 431 | ODbL 1.0 | Yes | Yes |
| Property listings — each agent’s own website Agents own this content. This site displays it with attribution and links every result back to the agent’s own page; it grants nobody a right to redistribute it, and it is deliberately excluded from the public code repository. | 1,619 | No licence granted | No | No |
| Law firms — Isle of Man Law Society register The Society publishes the register openly and its robots.txt permits access, but it states no reuse terms. Access is not a licence. | 50 | Unknown | Unknown | Unknown |
Contains public sector information licensed under the Isle of Man Open Government Licence. Source: gov.im — licence terms. The Isle of Man Open Government Licence is not versioned — the Treasury may issue new versions, and the current one carries no number — and its terms are stated to be compatible with the Creative Commons Attribution Licence 4.0 and the Open Data Commons Attribution Licence. The wording above is the statement the licence itself specifies for use where a fuller citation is impractical.
The two government registers that carry most of this site — the sold-price register and the planning register — are the freest of them, and that is unusual: the Isle of Man Open Government Licence grants a worldwide, royalty-free, perpetual right to copy, adapt and exploit the information commercially, asking only for attribution. This site attributes them on every page that uses them.
What this site infers, rather than knows
Several features are derived, and are labelled as such wherever they appear. Being explicit about them is the point:
- Address matching. Listings are joined to register and planning records by house name/street plus parish — not by a shared ID, because no shared ID exists. A property whose house name is shared with another can therefore mismatch. Every such section says so.
- Cost of works. Estimated from each planning application's own description text using published UK build-cost guides plus an Isle of Man premium. A guide, never a quote.
- The house price index. A repeat-sales regression over properties that sold twice. It cannot see improvements, so like every repeat-sales index it runs slightly hot.
- Property type and parish. Read from free text where agents don't declare them, so a minority will be classified differently than a human would.
- Duplicate listings. Where several agents market one property, the listings are grouped and shown once, matched on address and attributes.
What it deliberately doesn't do
It doesn't republish agents' phone numbers or email addresses next to their listings, doesn't invent statistics it has no data for (no fabricated "response times" or review scores), and doesn't present its own estimates as valuations. Where the Isle of Man Government publish an official statistic that disagrees with a figure here, theirs is the authority.
