We live a couple of suburbs away but it's only about a 10 min drive, max 13, sometimes 8

I wouldn't consider 20 min too long at all. Friends have just moved and are 20 min from school, a shop and 35 min from her work and 50 min from his work - they chose that and so far (6 weeks in) are loving it and don't mind the commute. By the same token there was a girl in my DD's Kindy class who moved out to the same area as these friends and she couldn't cope with the 20 min commute (and a 3 year old) and at the end of that year took teh kids out of school and is now in her second year of homeschooling (currently Year 2, Year 6 and Year 8 and the youngest Kindy)
