Rental prices for apartments in Dubai’s Burj Khalifa, the world’s tallest tower, have fallen by much as 40 per cent due to low occupancy in the building, Bloomberg has reported. Nine months after the tower was inaugurated about 825 of the tower’s 900 apartments remain unoccupied, Laura Adams, a residential sales and leasing adviser at Better Homes, told the news service. The cost of renting a studio with floor-to-ceiling windows, marble and wooden floors has dropped to AED6,666 ($1,815) a month, while a one-bedroom apartment is available for AED10,000, Better Homes said. Two-bedroom homes are going for AED15,833.
