When we started looking at buying a house, one of the houses we liked was close to my regular bike commute route, but at the top of a mile long hill. One of the first things I did was verify if I could make it up said hill at the end of a work day. It wouldn’t have been a deal breaker (that honor went to the flipper who outbid us), but it might have changed my commute.
We ended up buying in a different neighborhood, and now I walk to work.
