Manufactured housing doesn’t have to be ugly, some of the newer modulars are nice-looking and difficult to distinguish from site-built, but the more modules there are, the higher the cost. Still less expensive than comparable though.
Yes, I agree I have seen some very attractive manufactured homes ... as well as generally agreeable looking.
Still, the vast majority of them are butt ugly (and they didn’t have to be). It’s a shame really. I hope that is turning around and the reverse will be true, more of them will be attractive than not.
