Excellent advice from @Lorna170
I live in Md and when I purchased my home over a year ago, I wasn’t thinking of renting it out; but once I got settled in and started thinking of retirement, I decided to do so.
My basement is open but was already finished with a full bathroom. All I did was add a kitchen and a closet. My basement unit is large (815 SF) but I think a space of 400 SF with a kitchenette will work just fine for max 2 guests for short-term stays. If you’re looking for long-term, I think a galley kitchen vs a kitchenette would be more practical.
So, I’ll just say what I like about my space as a rental unit and things you should consider when house hunting with a future renter in mind.
*Open so unit feels spacious, not cramped
*Plenty of natural light coming in
*At least 7’ ft ceiling height
*I don’t regret adding a full kitchen. I personally did not want an oven so didn’t have one installed.
*Where I live gets really dark at night so I installed both path and motion lights (all solar)
*I like bigger furniture, which is more comfortable and I don’t want a guest afraid that they may break it.
*Walk-in level entrance. No stairs.
*Make sure there is good cable and WiFi reception in basement.
Good luck to you on house hunting.
