The Homeview/Sterling Downs area (near Nesbitt Elementary School) although at close proximity to Northampton is quite different. This area has a better neighborhood feel than the area on the other side of Ralston Ave. If you love Belmont and its excellent schools, then this would be a good neighborhood to think about as a starter home. The easy access to the elementary school, Hwy 101, the Belmont Sports Complex, the Belmont train station, etc. are some of the amenities.
Northampton is in a newer development (right across Oracle) consisting of townhouses and detached single family homes. There is a monthly HOA to maintain the common areas. The lot size of these homes tends to be smaller, so not much yard work for you to worry about. It is a small development that is well kept and desirable. Check out the long Bay trails by Belmont Slough and enjoy a run or walk. You will sure meet outdoor enthusiasts.
