Not sure if all of Farm Hills is Brighthouse or not (www.mybrighthouse.com
and punch in your new zip to make sure), but I know quite a bit of it is. http://michigan.mybrighthouse.com/
will give you a pretty good overview of what's available.
Naturally, OTA is the better route if all you want is network and you're not hungry for an HD DVR. Currently, the only way to get ALL of the networks in HD from Farmington Hills is via OTA, though that might change.
If sports in HD is important, consider DirecTV, which has the NFL Sunday Ticket in HD and seems to be showing some MLB in HD for those who have Extra Innings. AFIK, Bright House doesn't offer EI in HD.
That's about all the advice I can give ya.
