The home

Under contract with an inspection contingency intact

Went under contract in sixteen days at close to list with a standard inspection contingency and a 21-day appraisal deadline — worth noting, because the same house in 2022 would have gone with both waived. The Boulder market has returned to something a buyer can negotiate inside.

Represented by Ines Kovač. All measurements are approximate and taken from the assessor record; a buyer should verify square footage, lot dimensions and permit history independently during the inspection period.

Neighborhood

Newlands

North-west Boulder at the base of the foothills, on a gently rising grid that ends at the open space boundary. The Mount Sanitas and Wonderland Lake trailheads are within walking distance of most of the neighborhood.

Housing stock
1950s–60s ranches, many enlarged or replaced since 2005 with contemporary two-storey houses. Lots typically 6,000–9,000 sq ft.
Transit
RTD bus 205 on Broadway; the Broadway bike corridor into central Boulder.
Parks and open space
Wonderland Lake, Mount Sanitas, Dakota Ridge and the North Boulder Park block.

Under the Fair Housing Act we describe the place and its built form only — never the people who live there, and never who a home would “suit”.

An estimate only. Conventional 30-year assumptions, hazard insurance modelled at 0.35% of value a year, and mortgage insurance added below 20% down. Your actual payment depends on credit, debt ratios, reserves, occupancy and the loan product. A pre-qualification is a lender's opinion based on what you tell them; a pre-approval is based on documents they have verified. Sellers here take the second one seriously and largely ignore the first.
