Renting out a cabin/tiny home in your back yard

I’m thinking about setting up a tiny home or cabin in my backyard to rent out, but I wanted to hear from people who have actually done it.

- How much did you spend upfront (including setup costs like utilities, permits, etc.)?

- Was it worth the investment? How profitable has it been?

- Where did you buy your cabin/tiny home from?

Would appreciate hearing any experiences, whether you did Airbnb, long-term renting, or something else. I want to find out whether or not this is a solid way to generate extra income, and a good starting point to enter the world of investment properties.
