About Back Nine Dr

This impeccably maintained 2018 single-level plan delivers comfortable everyday living with an exceptionally large unfinished basement ready to elevate your square footage and resale value. Situated on a mid-block lot that backs to open space, the home presents stunning curb appeal and a private rear aspect — perfect for quiet evenings on the covered back deck.

Step inside to an extended entry and an open great room concept that accommodates multiple seating areas and a dining table for eight. Thoughtful details include 9' ceilings (10' in some recessed areas), engineered wood floors in the main living spaces, and a corner fireplace with a refined marble surround. The kitchen was designed for both function and entertaining: 42" maple perimeter cabinetry, slab granite counters, a curved island with seating for three, a walk-in pantry, and upgraded appliances including an LG InstaView refrigerator and GE gas range and dishwasher.

Three bedrooms provide flexibility. Two sizable secondary bedrooms are at the front of the home and share a full hall bath with storage. The primary suite is private, large enough for generous bedroom furniture, and opens to a luxurious five-piece bath with dual vanities, soaking tub, separate shower, water closet, and a Toto WASHLET bidet. The walk-in closet offers abundant storage. A dedicated laundry area with front-loading washer/dryer and a mudroom with bench and cubbies at the garage entry add real-world convenience.

The lower level is a major differentiator: a huge full basement that mirrors the main level and already has ceiling drywall in place and mechanicals positioned for a straightforward finish. Whether you plan a media room, guest suite, home gym, or rental income suite (subject to local approvals), the basement materially improves the home's utility and value without the premium cost of above-grade square footage.

Practical upgrades, quality finishes, and a location that combines quiet open-space views with access to Castle Pines amenities make this a compelling buy for downsizers, growing families, or buyers seeking value-add upside. Schedule a showing and tour both the polished main level and the substantial basement opportunity.

Neighborhood & Location

Castle Pines is an established, upscale suburban community in Douglas County known for wide streets, mature landscaping, and strong lifestyle amenities including golf, trails and parks. Residents value privacy, outdoor access, and proximity to Parker and Denver commute corridors. The area skews toward families and professionals seeking single-family homes with quality construction and nearby recreational opportunities.

Market Insights

Castle Pines remains one of Douglas County's desirable suburban enclaves with steady buyer interest for well-built single-family homes. In 2026 the local market is still favoring sellers in many price bands given limited inventory and sustained demand from buyers seeking proximity to open space and quality schools. Median prices in the general Castle Pines/nearby Parker corridor cluster near the $750K–$900K band; homes with one-level plans and unfinished basements commonly trade competitively because they serve both downsizers and families who want room to grow. For this property, the finished main level delivers immediate move-in comfort; finishing the large basement will likely generate an outsized incremental return compared with comparable above-grade additions. Buyers should act decisively — a combination of modern construction (2018), tasteful finishes, and the location backing to open space creates persistent buyer interest.

Key Findings

  • List price: $775,000; AVM ~ $778,400 (source data)
  • Living area ~3,938 sq ft; price per sf about $197
  • 3 bedrooms, 2 baths on main level; primary bathroom is 5-piece
  • Full unfinished basement ready for finish — reduces marginal cost of added livable space
  • Property backs to open space and sits on a mid-block lot; lot ~6,360 sqft

Things to Consider

  • Scraped parking flag shows no garage but listing text references garage entry — verify garage details and parking capacity
  • Exact school assignments should be confirmed with Douglas County School District (boundary changes possible)
  • No public tax/assessment data provided in the scrape — verify property tax and HOA/CCR obligations
  • Basement is unfinished — buyer must budget for finishing costs if requiring additional living area

Opportunity Analysis

Buyers who value one-level living and privacy get immediate utility from the finished main level; investors or owner-occupiers can add significant value and usable living area by finishing the large basement already roughed and partially prepared, increasing finished sq ft at a favorable cost per sf compared with above-grade construction.

Potential Use Scenarios

  • Owner-occupier: purchase and finish the basement (bedrooms, media, rec room) to increase living space and resale value.
  • Investor/flip: complete high-quality basement finish and stage to push sales comps into higher $/sf band.
  • Buyer: confirm garage and parking, verify municipal utilities and taxes, and order a thorough home inspection focused on basement/mechanicals.

Risk Factors

  • Cost and timeline for basement finishing may be higher than initial estimates (mechanical upgrades, egress requirements).
  • School assignment uncertainty for buyers prioritizing specific schools.
  • Market sensitivity to interest rates can affect buyer pool despite localized demand in Douglas County.

Buyers should conduct independent due diligence before making any purchase decisions.
