WITH dual-key units in private residential projects still well sought-after by home buyers, they could potentially unlock value for both developers and buyers in the current tight market.

According to global consultancy Knight Frank, demand for dual-key units is likely to be sustained from yield-seeking investors and families looking to house multi-generations under one roof.

"In a price-quantum sensitive market, larger units in a development tend to sell at a slower pace. The dual-key concept is one strategy adopted by developers to move the sales of these larger units," said Alice Tan, director and head of consultancy and research at Knight Frank.
