Granny Flat Investor Guide
Contact us today to schedule your free consultation!
A granny flat is one of the few ways to add a second income to land you already own. Skip the stamp duty, agent fees and Council approval.
Why investors build granny flats
- No land cost. You are building on land you already hold. No acquisition costs.
- Two incomes from one property. Rent the granny flat, or rent both dwellings separately.
- Faster approval. A compliant granny flat can be approved as Complying Development (CDC) under NSW state legislation, rather than through local Council.
- Added value. A quality, approved second dwelling widens your buyer pool when you sell.
