Worried that property prices may fall still further? Housebuilder Fusion Residential isn’t. Indeed, Fusion is so sure that prices will stay up, it is guaranteeing re-sale prices at Chenies Place, in Arkley, Herts.

Called Cenoption, the deal is based on a “put option”, as in the financial futures market. The concept is provided by finance company Centrila.

At any point between three to 10 years after purchasing a home at Chenies Place, the new owner has the ability to exercise the Cenoption and sell the property at its initial valuation, regardless of whether property prices have fallen. If the property increases in value, there is no obligation to sell the property to Cenoption, so purchasers can benefit from the growth in value.

Gavyn Fresco, head of sales and marketing at Fusion Residential comments: “We are proud to provide homeowners with such peace of mind by putting in place the Cenoption free of charge.

“At a time when homebuyers are far more discerning, the Cenoption gives them the ability to commit to a property without worrying about the uncertainty of the property market.”
