This is a recent little cabin project I did on a block. I guess something similar could be called a granny flat. Most these projects come in at 100-140k I was able to do a few secrets to get costs way down. These things rent for around $150 week in this area. It could have been 10k cheaper but council force you to do things that do not make any sense and or are even needed. I used this spreadsheet below to keep track of the costs as the project progressed. It’s just my personal in-house spreadsheet I thought I’d share it.
After the project was done and AirBNB was the new thing around I tried it for a year and was a great success, I have seen travelers from all over the world come stay at my little place. I met some amazing people. Then I put a permanent tenant in, so I could travel some more.
