About this House
A change in the Seller's lifestyle has created a rare opportunity for a fortunate new Buyer to own at the coveted Mapleton Ave Condos! An amazing location at the corner of 4th St and Mapleton, this top floor, west facing, end unit condo has multiple decks and is ready for your creative touches. The kitchen and bathrooms have been demo'd so the condo will need to be purchased with cash or creative financing. Even with the unfinished condition, you can't help but notice that the soul of the unit is its warmth, incredible natural light, high ceilings, original wood floors, and brick walls. Enjoy access to all the best that Boulder has to offer from the Sanitas hiking trail to the vibrant downtown lifestyle. This unit is the largest in the complex, offers a front and back entry and even boasts a one car detached garage. Unique, extraordinary and highly desirable on Mapleton Hill... come and take a look.
