Hi Guys, I'm considering purchasing an old 5Bed house with granny flat built in rear. Flat has its own seperate driveway and is completely fenced off from main house. The price is extremely attractive under 300K (if I could rent separately I'm talking close to 10% yield), catch is the granny flat is not registered and there are no plans available. I inspected the granny flat build looks well done. Footings, stumps and pluming look good as well as correct legal spacing to boundaries. I called a local building certifier who said I would have to get plans drawn up, get a builder on board to take 'ownership' of build for insurance purposes and it would cost me best case under 10K but worst case up to 30K. Has anyone here had similar issues and what they did about it? I'm happy to pay say upto 20K to get all issues solved, but I cannot be given a 100% yes answer from council so I'm scarred to take the leap. Agent has hinted that because it is not a capital city and council is not so strict I could just get separate water and electrical meters installed and rent it out separately without any issues. Cheers for any advice.
