About this home

On a quiet country road with views in all directions, you'll find this original 1967 ranch style home (2024 sqft) with an unfinished addition of 2012+/- sqft. which does not include the 1584 sqft garage area with almost 1400 sqft in a bonus room above. Unfinished master suite (552 sqft) bringing the total potential sqftage to 5620+/-. This is an incredible opportunity to finish this home in the style you desire. Assessor's records only show 1 acre of record, but the AP map indicates almost 3 acres when you look at the area on the other side of Middle Creek which bisects the property. There's a 3 bedroom 2 bath in the original home with a large new master and master bath waiting upstairs to be finished. This may work with a purchase-construction loan, talk to your lender. This is a whole lot of house waiting for the finishing touches and your personal design ideas! The garage is a car collectors dream as there is also a smaller detached 2 car garage on the other end of the house. Room for all the toys, boats, whatever. Original approved building plans available and included in sale. GREAT OPPORTUNITY FOR CONTRACTOR OR INVESTOR!
