Better questions.
Fewer blind spots.

The doors may create privacy, but the ownership, financing and eventual sale are usually considered at the property level.

• Do not assume the suites can be sold separately.
• Check the title and approved plan before relying on the layout.
• Model the purchase as one property even if two households will occupy it.

Gross monthly rent is the easiest number to advertise—and the least useful number on its own.

• Allow for vacancy, leasing, repairs and recurring costs.
• Test demand for the actual suite size and privacy level.
• Use net income when comparing against the mortgage.

Trace each household from the lift lobby to bed, bath, food and laundry. Every forced crossing is a clue.

• Look for independent daily circulation.
• Check windows, plumbing walls and acoustic buffers.
• Imagine reconnecting the home for a future buyer.

Multigenerational living works when support is easy but autonomy remains visible in the plan.

• Prioritise accessibility and safe night-time movement.
• Give the smaller side a dignified place to sit and eat.
• Agree what is shared before moving in.

The extra price should be measured against both financial return and the replacement cost of the family outcome it creates.

• Compare with a similar conventional unit.
• Separate family utility from investment return.
• Check whether the premium is recoverable on resale.

Flexibility is only valuable if another household can understand and use it later.

• Avoid layouts that work for only one unusual arrangement.
• Check whether the main home feels compromised.
• Prefer clean reconnection over permanent fragmentation.
