Homes within the £1-1.5million bracket also increased – 59 were sold last year, up from 37 in 2014. This was a 11 fewer than the previous year, however, when 78 were purchased.
25 properties priced between £1.5-2million were sold in 2017.

But while luxury properties saw a spike, the figures – released today in the States Statistics Unit’s quarterly House Price Index – showed that islanders favoured flats in 2017.
Sales of flats increased by more than a quarter, while house sales declined by 6% from 2016 to 2017.
A one-bedroom flat was priced at £227,000 on average in 2017, around £8,000 higher than 2016.
One-bedroom flats peaked at an average of £255,000 in early 2008, but an increase in turnover of lower-priced share transfer properties helped to drive down prices over the following years. Over the past five years, however, mean prices have gradually increased.

Two-bedroom flats averaged at £355,000 last year – up £6,000 from 2016. It was the highest annual average recorded to date.
The majority of these – around 30% – cost their buyers £320,000 to £360,000, but one in 10 sold in the last quarter were £480,000 or more.
Three-bedroom homes were found to have undergone major fluctuations over the years – prices saw strong growth in 2006 to 2008, and remained stable thereafter. In 2011, they fell below £500,000 for the first time since 2007, but sat last year at around £556,000 on average – the highest ever recorded.
The mean price of a four-bedroom hit its highest ever quarterly high in late 2017 at £884,000. It constituted an increase of as much as £44,000 compared with the previous quarter, and was £60,000 higher than the annual average for 2016.
