It's not for everyone, for sure. I was renting the rooms already to long term lodgers for several years, so it wasn't such a leap for me. There are pros and cons to both lodgers and guests. I do find that guests in general are cleaner and tidier in communal areas, including the kitchen. They are also highly unlikely to act like they own the place.
I would love to have my own private bathroom, but it's just not possible with the way the house is set up. That could only work if I rented out one room rather than three. Anyway, I am used to it. Even before I bought this house, I was renting out the spare room in my flat, which only had one bathroom.
But yes, it can be stressful at times and I have found it more so these past few months as difficult guests seem to be on the increase. It can be very uncomfortable sharing your home with certain people. Luckily those are still the minority (for now).
