I have a house in Western Sydney (2770) and am torn between selling the house to pocket the gains before the music stops and building a granny flat to increase the cash flow to help with serviceability. I've asked my property manager about the demand for granny flats in the area and, in her reply, she pointed this out... "Extra income on the same property is definitely a pro and ensuring that the tenants are suited to one another may be a con." Wondering if you have any information to share regarding the highlighted above. What sort of issues have you found trying to lease a granny flat? Any issues with tenants not getting along and being too close to each other? In your experience, it is harder to rent a house AND a granny flat? This is not the main consideration when deciding whether to sell or not, but it would be good to understand what I am getting myself into before committing. Thanks!
