I would think a lot would depend on if you are personality compatible. I could have lived with my in-laws much more so than with my own parents. My FIL always had me laughing, and we got along great, and my MIL wasn't too bad. I loved my parents - don't get me wrong - but I just couldn't have lived with them. My father even made the suggestion one time that he would finish the basement for an apartment for me and my now ex. We thanked him and declined the offer.
