I agree with the others. Don’t even worry about what this ignorant neighbor thinks. I think it makes great sense if you don’t mind having someone live with you.
My neighbor many years ago was fairly well to do and did the same thing. Not only for the income but she traveled quite a bit and she always loved that someone trustworthy was there to watch the house.
She did set a few ground rules. She only rented to University students or recent university graduates and only rented to females.
I was actually single at the time so I loved it as she always seemed to find the cutest girls! Ha, ha. Seriously though, it worked out great for her. I think she was charging something like $800 a month and this was back about ten years ago.
She always rented to really great students and the students got to live in a great area in an amazing house. My neighbor always traveled with the extra money.
Her kids were all in college, she was divorced and I think part of it was she was lonely as well so the company was great. But I always thought it was smart.
Don’t waste your time worrying what other people think about the situation. Definitely it’s a good plan.
Me personally I could never do it. Even when I was single and living alone and had a big house I always liked my privacy but I think it’s a great option for people that have the space and need the income just as long as you are carefully screening the people that will live with you and you also set some guidelines and rules for them.
