Withdrawn applications are counted in "decided" but never in a success rate — a withdrawal is usually a redesign, not a refusal.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.

Geography
Where is the biggest price gap in Guernsey?
The median home in St Pierre du Bois asks £1,950,000; in Alderney it asks £445,000. Same island, 4.4× 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 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.
