When I moved, the commute was a top-3 factor, but I rent an apartment. Buying, it would likely be lower in the list.

My commute is 8 miles door to door, 5.x miles if I don't take the Greenway. That's pretty similar to your choices - most of the time, I choose to take the 8 miles with the Greenway. The commute time is about the same either way.
