Benefits of building with Coastwide Grannyflats
Additional income, with up to 15% ROI
Granny flats have great potential for generating excellent rent returns with up to 15% return on initial investment.
Alternate living solution
A granny flat is a great alternate for living arrangements for extended family or the children.
Help children enter the property market
If your children are having trouble entering the property market, perhaps a granny flat is an opportunity for them to buy into the family property.
Independent lifestyle for older relatives
Granny flats are a great space for the retiring parents to downsize from their homes and live near the family. Independent living that still gives them their own home.
Increased property value
Adding a granny flat maximises property values by increasing its return on investment value for investors.
Intelligent use of extra yard space
Are you tired of maintaining that extra yard you don’t use. Granny flats are compact and have little maintenance costs.
You can have your brand new granny flat built in as little as 12 weeks and receive up to 15% return on your initial investment.
