312 Marin Avenue Sweet Single level Kay Park home with a big quiet backyard next to Crest Marin Creek. Step out your front door for outdoor adventures in the woods, waterfront trail and all the shopping and dining options down the street! The relaxing Tamalpais Valley neighborhood of Mill Valley, 312 Marin Avenue offers an exciting opportunity to settle into one of Southern Marin's most loved communities. Open concept living with kitchen, dining and living room all facing the level backyard (with fruit trees!), and a garden shed and garden beds. The long-time owners lovingly updated this home and gardened the soil to create a peaceful place they called home for 20 years. Originally built as a 3BR/1BA home with a one car garage, the owners captured part of the garage for laundry and office space, with ethernet for an additional WFH area. The home has newer windows and doors and roof and a grey water irrigation system. These meaningful updates provide a strong starting point for the home's next owner.
