About This Home

Woooheee! What a deal! Investor Alert! This unique duplex property is a dream waiting to happen! Original 1-1/2 story home with finished basement is 2,200 sq ft, with 4 bedrooms, and 1.75 baths, fresh paint, a newer roof (approx 10 years or less), and a brand-new furnace (just needs a thermostat). Connected by a breezeway to a 1,203 sq ft rambler built in 1960 with a new roof, fresh paint within 5 years, and a massive 1,112 sq ft garage/shop! So many options: rent both, or live in one and rent out the other, plus potential to build an ADU-hello cash flow! Located on a corner lot and short dead-end street for added privacy. With vision and a little TLC, this property is a rental powerhouse in the making. Don’t let this unicorn get away!
