If our character is from Baldur's Gate, shouldn't they already have a house - or at least a residence - somewhere? Were we all living on the street?
I thought it's depending on the background, right? I'm not sure how it goes with certain races since I don't know if they're from Baldur's Gate like Gith? It's depending, but really, renting or buying or guild, mainly just a stronghold base would make sense for me rather than just wandering aimlessly throughout the city.
