What is Dual Key?
Dual-key units is a very interesting concept.
One main door with 2 separate entrances with a possibility of renting out to 2 groups of tenants. 2 independent units with each holding a separate set of keys. Usually is in a form of 1 side studio unit, the other a 2 bed or 3 bed room unit.
The studio unit, with its own kitchen and bathroom, has a separate entrance which opens to a foyer that is shared with the main unit.
Maintenance fees is as one whole unit. Rental Price usually market practice is included in unless you want to specify otherwise.
Why Dual Key?
Expats working in Singapore needs to rent a place to stay alone or with family. Those alone will look for a studio and those with family will look for a 2 or 3 bedroom to rent, as they may not wish to pay the 10% Additional Buyer Stamp Duty, ABSD.
Singapore government is encouraging children to stay with or near their elderly parents. Dual Key encourages multi generation to stay together and has their own privacy.
