I think you are right on ther. > As an aside, I'd like to have property borders show up as a very light > gray, similar to the way Google Maps now displays property borders in > the US (the areas I've checked, anyway).

But I'd make them not boundary/admin_level because they are different. I believe that in Mass lot lines can straddle town boundaries - but I'm not 100% sure. They are definitely not political boundaries though. So how about boundary=lot to denote an area which is registered as a unit in a registry of deeds, or the equivalent. A related need might be to group contiguous lots under common ownership which are treated as one logical lot.
