Steep Hollow, Edge, Kurten, Gause, Mumford, Snook in a pinch.
All of those more fit the description you gave. Brenham & Huntsville both have significant college populations. Caldwell is not exactly an "older" town for that matter.
Rockdale will have good "buy" points, what with Alcoa closing, but, that commute would be a killer, especially getting stuck in a two-lane-train behind a slow-poker on 21 (and a lot further to stay on 79 to Hearne and turn right).
Given the distances you are talking about, you could look to Cawthon or Washington--other than the shortest way to town gets you into the worst of the commuter traffic on Wellborn. Independence might make sense, you could take 50 to 60 and get into town, or you could take 390 over towards Washington, and have two options, 105 to Navasota and then 6; or 159 to 2154.
Really though, there are plenty of grown-ups in BCS as is; living 1-2 hours' away to not be near "college kids" might be a tad over-the-top.
