I found this really nice room in a very nice, quiet house to rent and best of all it's in a really quiet, rich part of my old neighborhood (the neighborhood I grew up in and came to love over the years). The room is cheap and I can use the kitchen, living room, etc... as I please. It really couldn't be better, but of course there's a catch. The house was built in 1929 and it doesn't look like the interior was ever painted/remodeled since the year it was built. The room which I would be using has beige-colored paint on the walls and this paint is chipping. None of it is comming off but it is cracked and some parts look like they would disintegrate if one was to press on them. This isn't a big problem in itself, but I'm worried that the paint is lead-based. What are the chances that it is? Is it pretty much 100%? I read somewhere that exterior paint is more likely to contain lead, is this true? Like I said, the house was built in the 1920s, the paint is on the interior and is beige-colored. Also the paint is not opaque.. as far as I remember. Should I ask the owner about it?
