Fantastic value in this single story home--great location, new dual paned windows, large pool size lot, and recent exterior paint. It's time to replace the flooring and update the kitchen--make it just the way you like it! The owner also recently trimed all the trees and replaced the garage door opener. Lots of possiblities in the yard with the privacy of noone behind you. This is a standard sale--ready to sell quickly!
