Remarks

Your Oasis Awaits! This charming 3 bedroom, 2 bath house with a 2-car garage/shop gives you approximately 1,511 sq. ft. of living space to call home. Sitting on just over half of an acre, this home comes complete with an amazing Casita. The Casita (ADU) is equally amazing and completely ready for your family members or income producing opportunity, boasting 512 sq. ft., 1 bedroom and 1 full bath with an amazing kitchen. Both of these beautifully kept homes are move-in ready. Most of the big-ticket items are already done! To name a few, there is an updated HVAC, newer windows and they have been fully remodeled. And if you’re not enjoying time indoors, the huge yard is simply waiting for you. There is a half an acre of fully fenced property, with an electric security gate. Here you are free to let your children run and play, while you lounge by the fire pit or exercise your green thumb in the small but established fruit tree orchard. To top it off, there is also a chicken hotel, just waiting for new residents. This is the perfect house whether you’re into just watching your chickens mill about or enjoying the simple sounds of children playing. We invite you to lounge about in the private backyard, because this is the one.
