This one-level home offers a great location - close to transportation and shopping. The floorplan is a traditional ranch style home, with an expanded family room having a cozy fireplace. It has newer dual pane windows, and a level front & back yard. Includes a detached building being used as a shop - it could be re-purposed for other uses. Solar panels are leased - to be assumed. With some updating it can be perfect for the new owner.
