I lived at home and commuted via public transportation 1.5 hrs each way 6 days a week for 2 years of residency, but I wasn't driving, so I was able to sleep each way.
In retrospect, I probably could have swung it financially to live closer to the hospital, bc working 6 days a week for 2 years- I didn't really have the time to spend much money on anything else anyway.
My observation of my previous residents however: residents who lived within walking distance demonstrated poor time management skills and frequently spent what I think was way too many hours at the hospital, whereas residents who had to commute a considerable distance were more regular in their work bc it was their very commute that forced them to get their work done and get out of the hospital at a reasonable time.
If your differential in commute times is 30 vs 60 min, so meaning only 30 min, I don't think commute time should be your deciding factor for your rank list. Good luck!
