What the data says about Jersey
Not opinions — arithmetic. Each of these came out of the registers and the listings themselves, and each links to the page it was computed from so you can check it. 13 of them today.
Geography
Where is the biggest price gap in Jersey?
The median home in St Martin asks £1,725,000; in St Helier it asks £450,000. Same island, 3.8× the price.
What would make this wrong: It compares what is on the market, not like for like. An area of large houses will always beat an area of flats, whatever the land underneath is worth.

What things cost
Which bedroom costs the most in Jersey?
Going from 4 bedrooms to 5 adds £815,000 to the median asking price — more than any other step on the ladder.
What would make this wrong: A 5-bed house is not a 4-bed house with a room added — it is usually a bigger plot in a different place. This is the price of a different kind of home, not the price of a bedroom.

What things cost
Where does a square metre cost most in Jersey?
St Martin asks £8,229 per m²; St Ouen asks £6,509. The same 100 m² flat differs by £172,000 depending only on where it stands.
What would make this wrong: Only the listings whose agent published a floor area are in this, and agents measure differently. Condition and outside space are not in it at all.

History
Has Jersey property ever actually fallen?
Yes — 2024 was down 11.2% on the year. Across the whole series the index has gone from 100 in 2001 to 249.5, but it has not been a straight line.

How people behave
How long do people keep a home here?
Half of all repeat sales are 2.7–7.8 years apart, with a median of 4.7 years. That is how often a given address comes back to the market.

Asking prices
Are sellers in Jersey asking more than the market has moved?
On the 483 homes for sale that also appear in the sold register, the median asks 2.3% more than the index says its own last sale is now worth. 191 are above the index, 178 below.
What would make this wrong: The index cannot see what has been done to a house between sales. A property extended since it last sold should ask more than the index says, and plenty have been.

Planning
What is hardest to get permission for in Jersey?
Applications for new dwelling are granted 77% of the time, over 68 decisions; signs and shopfronts 95% over 75. Both are high — refusal is rarer here than people assume.

Development
Where is Jersey actually being built?
St Helier accounts for 25% of every new dwelling proposed on the island — 120 of 477.
What would make this wrong: Proposed, not built. One large scheme can carry a whole parish, and a refusal or an abandonment leaves the number standing.

Geography
Which is the dearest road in Jersey?
Petite Route De Campagne, St Peter — a median of £2,750,000 across 14 recorded sales. The busiest road on the register is La Route De Beaumont with 359.
What would make this wrong: Roads are matched from the register's own address text, so a short prestigious road with few sales can be beaten by a long ordinary one. The median spans the life of the register, not today.

The market
Do agents agree on what a house is worth?
107 properties are marketed by more than one agent here, and on 9 of them the agents quote prices more than 2% apart. Both figures are published as given.

Supply
What is the cheap end of Jersey actually like?
Only 218 of 1,874 homes for sale — 11.6% — ask £300,000 or less. The bottom of this market is thinner than most people expect.
What would make this wrong: Cheap homes sell fastest, so at any moment the bottom of the market is under-represented on any listings site, including this one.

The island most like this one
On asking price and market size, Guernsey is Jersey's closest match anywhere on this site — a median of £745,000 (£745,000) against £715,000 (£715,000), across 1,147 listings against 2,179. Put them side by side
What the same money buys elsewhere
The median Jersey asking price, converted, against other islands' medians.
| Island | Their median | What Jersey money buys |
|---|---|---|
| Samoa | WS$250,000 | 10.5 homes at their median |
| Dominica | $204,598 | 4.8 homes at their median |
| Belize | $235,000 | 4.2 homes at their median |
| Bahrain | BD 90,000 | 4.1 homes at their median |
Converted at the previous day's reference rates. It compares medians, not like-for-like houses — an island of flats will always look cheap against an island of villas.
