Sino Land has sold 50 units since Friday in its Island Harbourview project above the airport railway's Olympic Station.
Buyers were attracted by mortgage rates at or below the prime lending rate and the possibility of 85 per cent financing, said property agents.
The Sino Land-led consortium had taken advantage of improved market sentiment since the Lunar New Year to relaunch the Tai Kok Tsui project, they said.
The agents estimated the consortium had sold about 80 per cent of the total 2,340 units before the relaunch.
They estimated the developer was trying to sell about 200 to 500 units this time.
'Many people who could not buy a flat in [Cheung Kong's] Laguna Verde project in Hunghom ended up out at Olympic Station,' said Henry Ho, Midland Realty sales manager for West Kowloon.
He said the projects were similar because they both provided luxury units with good sea views.
