NakedBudd saidI've lived with roommates since college. I am a roommate kind of a guy, would not like living by myself.
Today I own a 4BR/2BA house and rent to three other guys. Their rent pays my mortgage (in full, with some left over building a cushion for repairs) and I live here rent-free.
I highly recommend it!
A friend of mine back in my mid 30s did that. I thought it brilliant. Also he was into twinks so rented to them. He had a five bedroom house, pretty much a nonstop party. It was pretty fun.
I've been living on my own for too long now and am tiring of it. So I'm setting up the master bedroom with its own bath to rent out. To the OP's question of being comfortable, I'll absolutely assure my housemate feels that "mi casa es su casa".
The room will come furnished with desk and extremely comfy pillowtop mattress. All house privileges of course. I've got a murphy bed and a sofa bed for his out of town company and about an acre (intown, love it) for his dog if he cleans up droppings every day (I do the same when I have a dog) and keeps the pup bathed.
I'm a natural for having a housemate, having spent most all my summers growing up from when I was a little kid sleeping in bunks at summercamp, having lived with parents who enjoyed having my friends sleep over frequently, whether they were home or not (and sometimes every bed in the house was filled with them), having been used to entertaining guests overnight, aboard while boating with my parents or my partner, and having done a lot of entertaining in my homes, particularly in my 20s-40s. My best bud and I used to go up and down the Intracoastal picking up strangers off the seawall to entertain them for the day. They're only strangers until you start talking.
Treating guests as family was very important to my family. We've rarely had less than 20 at our Thanksgiving tables and now my sister-in-law has taken up that tradition. My stepdad felt the same. He had a saying whenever an unexpected guest stopped by during dinner time "Family Hold Back". You make sure the guest has what they want to eat before you satisfy your own desires.
So in the right situation the OP shouldn't feel awkward at all about living with another person. And as far as it being a stranger, man, I've been so much more screwed in life by people I thought I knew well and loved deeply than by people I've just met. And I have mostly nice family and friends.
My only concern these days is that I don't think I'd be crazy about someone bringing a lot of unknown tricks into the house. I have no problem with someone entertaining their friends overnght but I'd rather they treat this place as their sanctuary as do I. So my interview process will probably include some questions I'd rather not ask but that I feel I need to clarify before committing.
Generally I'm pretty easy going. My brother always joked with his kids. If you don't like it, why don't you just go over to your uncle's house. There are no rules at your uncle's house.
Well, there's one rule: make yourself at home. Which is just another way of saying: you want something to drink? You know where the fridge is. Oh, and while you're in there, grab me a beer.
