What Does Dual Key Condo Mean | Dual Key Condo Explained

A dual key condo has two units – a main one and a smaller studio unit. Both are under one address. They share a main door and lobby. This setup lets you own two places but pay the price of just one. Plus, you won’t need to pay extra taxes (ABSD). The idea of getting two homes for the price of one started over ten years ago.

Key Takeaways:

  • Dual key condos consist of a main unit and a smaller sub-unit under a single address.
  • The units are linked by a shared main door and lobby or foyer.
  • Dual key condos allow you to own two units for the price of one, without having to pay ABSD.
  • They provide a versatile housing option and have become popular in Singapore’s real estate market.
  • Investing in a dual key condo offers the potential for rental income and cost savings.

What is a Dual Key Condo Layout?

Dual key units stand out from regular condos. They offer extra space and unique living arrangements. These units have a big part and a smaller part, each with its own entrance but sharing the same address. It’s like having two homes in one.

One cool thing about dual key units is the shared entrance. A main door connects both the main and the sub-unit. This design can be different in each unit, to fit different family sizes or personal preferences.

The sub-unit in some cases is fully independent, with its own bedroom and living space. But in other situations, it can share the kitchen with the main unit. This makes it great for both family and rental use.

In these layouts, owners can use the sub-unit for various reasons. It’s perfect for families who want to live together but have some separation. Or, it can also be rented out to make extra money.

In conclusion, dual key condos are all about adaptability. They allow homeowners to use the space in ways that best suit their needs. Whether it’s for family or financial reasons, these units offer a lot of freedom.

Benefits of a Dual Key Condo Layout:

  • Increased floor area compared to typical condo units
  • Flexibility to use the sub-unit for different purposes
  • Potential for additional rental income
  • Versatile living arrangements for multi-generational families

The Upsides to Getting a Dual Key Condo

Dual key condos have many perks that attract homeowners and investors. One major boon is getting around the Additional Buyer’s Stamp Duty (ABSD). If you own a dual key unit and rent one or both sides, you can dodge this big tax.

Developers also like dual key condos because they offer double the rental potential. This suits various living situations. They are great for families living together or if you work from home. You can easily turn the extra space into an office, boosting both your lifestyle and your work.
