I have lived in the East Valley and Evergreen areas for over 25 years. I owned a home on Decker Way which is just west of Fleming and we were surrounded by great neighbors. Fleming area has a lot of great homes and you are very close to the prestigious San Jose Country Club. I enjoy the area and have recenty put an offer in on a home, just west of Fleming. I feel you get the most bang for your buck and less of that hustle and bustle feeling in the hills of East Valley. I truly believe that people are missing out by not looking more closely at living in this area.
As far as traffic, you do have a backup in the morning and the evening, but it is nothing compared to our other major slowdowns in the south bay.
If you really want to get the scoop on the Alum Rock area and the foothills, just stop in at Mario's Barbershop on Alum Rock and the guys will give you the complete lowdown!
I wish you the best on your purchase and good job thinking out of the box on the underappreciated and under-valued area.
Have a great weekend!
