Dual Key Condept

---

What is a Dual-Key / Dual-Occupancy Home?
A dual-key property is two self-contained living spaces under one roof on a single title. Each side can be rented separately, giving investors two income streams while keeping the convenience of a single property.

Why investors like the concept:

• Higher rental income with two tenancies
   
• Reduced vacancy risk — if one side is empty, the other still pays
   
• Suitable for families, couples, FIFO workers and downsizers
   
• More flexibility: live in one, rent the other, or rent both

Below is a simple and realistic example showing how dual-key income can outperform a standard house.

Scenario 1 – Standard Single House (Perth median):

• Purchase price: $780,000
   
• Typical rent: $680 per week
   
• Yearly rent: $35,360
   
• Gross rental yield: 4.53%
   

Scenario 2 – Dual-Key Example (Two rentals in one home):

• Approx. purchase price: $880,000
   
• Combined rent: $1200 per week (For example, $650 + $550)
   
• Yearly income: $62,400
   
• Gross rental yield: 7.09%
   

What this means for an investor:
For roughly a 10% higher purchase price, the dual-key property earns around $6,240 more income per year and provides two rental streams instead of one. Even with conservative numbers, the dual-key delivers a higher gross yield and stronger weekly cashflow.

• Rents are strong: Perth rental demand continues to rise, and vacancy rates remain historically low.
   
• Better cashflow: Two rents can outperform a single tenancy even if each side earns slightly less individually.
   
• Lower vacancy risk: If one tenant moves out, the second unit still generates income.
   
• Appeals to multiple market types: Families, downsizers, retirees, FIFO workers and investors.
   
• Wider resale market: Future buyers may include investors or owner-occupiers wanting multi-generation living.
