A fictional estate agency has revised an island's particulars after discovering that its principal feature, location, was subject to a degree of flexibility.

The brochure originally promised seclusion, mature trees and excellent access to a nearby shore. These remain accurate, although the agency now asks buyers to specify which shore and at what time.

A negotiator described the movement as an unusually dynamic neighbourhood. Where conventional properties require residents to relocate for a change of scene, this one periodically undertakes the work itself.

The mortgage application has encountered difficulties. The lender accepts floating interest rates but had not intended the property to participate. Its valuation team is waiting for the asset to remain within the surveyor's travel allowance.

Prospective buyers asked whether the island's arrival near another settlement might affect the school catchment. The agent said this depended on the wind and should be discussed with an independent adviser.

The existing owner is delighted by the increased interest. He had initially feared a problem with the map, before realising that the map had simply failed to keep up with the market.

Viewings are available by appointment and subject to the island attending. The agency recommends arriving early, although this advice may merely allow more time to watch it leave.
