When I was studying oversea (near a high cost of living city), I rented a 3 bedrooms house. Then rented out other bedrooms spaces and didn't have to worry about the rent.
At that time, I think I would rent out working space
For students / young professionals to rent out spare rooms in their house. Especially if they are going into work or campus, they can earn a bit of extra income.
This is essentially very similar and you could even rent out accommodation and working space.
I also had a few AirBnB to fill up the places when there was spare bedrooms. It was great
and ofcourse, there are the dark side to watch out when you want to implement it.
Ever have any problems yourself?
