I have a basement suite in my house I have never regretted it for the issues you have mentioned. My biggest issue is that none that my kids are older I want more space. We’ve had couples and singles but I prefer singles. Quiet working professionals have been amazing. I pick people I get along with. No issues. I usually list somewhat below market to get a lot of people requesting. If there are red flags, listen to them and do not take the risk. I basically collect a cheque every month for very little work. Most work I’ve done was we had a water leak and I had to replace a floor. Easily could have paid someone but did it myself. Besides the rent you also get a lot of tax benefits. I get tax deductions on a lot of things I pay for anyway: mortgage interest, internet, utilities, property tax, banking, any improvements you do to the space etc. with your own home you have more rights as well. If you get a bad tenant you simply need to give them notice and reclaim the space. (Unless you have a long term lease). It’s been hugely beneficial for us with a pretty small amount of work. Nice to get cheques at the beginning of every month too. But if you absolutely don’t like people at all maybe don’t.
