The Jersey house price index
Built from 4,625 pairs of sales — every address in the register that has sold at least twice — so it measures the same buildings changing hands, not a changing mix of what happened to sell. 2001 = 100.

What a past price is worth now
Carrying a price forward by the index answers "what would that have to be today to be the same purchase" — not what the house is worth, which depends on the house.

How it is built, and what it cannot do
- Only addresses that sold twice count, and only pairs at least nine months apart. A year is published only once at least 40 sales sit behind it.
- Pairs where the price moved more than eightfold are dropped — that is a rebuild or a data error, not the market.
- Nominal £1 transfers are excluded entirely.
- It cannot value a specific house, and it says nothing about a property that has been extended between sales — that improvement shows up as "the market", which is the known weakness of every repeat-sales index.
