Withdrawn applications are counted in "decided" but never in a success rate — a withdrawal is usually a redesign, not a refusal. Categories are matched from the application's own wording, so a description mentioning two kinds of work lands in the first that fits.

What things cost
Which bedroom costs the most in Guernsey?
Going from 4 bedrooms to 5 adds £405,000 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.

History
Has Guernsey property ever actually fallen?
Yes — 2016 was down 4.1% on the year. Across the whole series the index has gone from 100 in 1995 to 591.2, 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 3.1–9.9 years apart, with a median of 5.5 years. That is how often a given address comes back to the market.
