I have, too, and for some reason always assumed it was either some sort of abandoned funeral home or a sort of religious organization artifice, a meeting or banquet hall or something. It was always just a bit to clean, dark, and empty to be a regular house.

Me, too. I kinda assumed it had been annexed by the church next door. One of the churches in "downtown" Cary had done something similar (bought a number of the surrounding homes for extra meeting/education/banquet space).
