About this home

Here is a really cute single family home on a quiet street in the upper valley neighborhood of Castro Valley. Built in 1950, this home sits on an oversized 7,650 sq.ft. lot, making an ADU or addition easy to accomplish. You will see many properties with second story additions in this neighborhood. This property is located away from the busy downtown area, yet is still within walking distance to downtown restaurants and shopping; Castro Valley weather is perfect -- never too hot or cold! This cute cottage style home has an open floor plan, larger bedrooms and a one car attached garage. The refrigerator, washer and dryer convey with the property. A small stream lies beyond the backyard fence and the landscaping is pretty. It is common to see deer, racoons, squirrels and birds often and the location is extremely quiet. This property is served by the Castro Valley school district rather than the Hayward school district. The neighborhood is primarily owner occupied. BART is one mile away, 4 min. by car or 20 min. walking. The 580 freeway is 5 minutes away. Open Sat/Sun, 8/5 and 8/6, 1-4PM. Attractively priced! Offers reviewed 8/10.
