I load the CENSUS meta data for the various dataset types into R and then search on either the label field or "concept" field using grep in R. When I grepped on "TENURE" quite a few tables came up. The metadata doesn't have a "universe" field so I didn't pick up the person level table when I searched. After your help I went back and dug in further and B25003 was there. Oh well.

PS for other who might use R, tidy census has a function that can be used to search the metadata datasets.
