Large Lot 4-Bed Bi-Level in Quiet Thornton Cul-de-Sac
This bi-level home at 1501 E 98th Ave delivers rare scale and renovation potential in a quiet Thornton cul-de-sac. The generous lot — 9,598 SF — is the standout feature: deep rear yard space creates room for a meaningful outdoor program, whether you envision a patio and garden, play areas, or a custom entertaining yard with room for expansion. Inside, roughly 1,800 SF is distributed across upper and garden-level living areas that give you flexible separation for family life and work-from-home needs.
Four bedrooms and two full baths provide strong day-to-day functionality. The entry opens to a central circulation point, with the upper level providing primary living spaces and the garden level delivering secondary living/rec room space that transitions directly to the backyard. Original-era details are present throughout (including a bay window), and the layout has solid bones — an ideal candidate for a thoughtful cosmetic and systems refresh to unlock value.
The home is sold AS-IS and represents an attractive opportunity for buyers who want to add immediate equity through targeted updates. The oversized lot alone separates this property from many comparables in the price band and should support added value when the interior is modernized. Practical features include an indicated 1-car garage and driveway parking; confirm configuration during your showing.
Location is highly commuter-friendly: easy access to I-25, nearby shopping and services, and regional connections to Denver and Denver International Airport. This property will suit an owner-occupier looking to personalize a long-term family home or an investor seeking a single-family value-add in Thornton.
Schedule a showing with the listing agent to evaluate the property condition and discuss scope for improvements — with the right vision, this lot and layout can deliver meaningful upside.

A factual market snapshot around 1501 E 98th Ave.
Thornton sits on the more affordable edge of the Denver metro, and this segment (northeast Thornton/80229) attracts buyers seeking larger lots at lower price per square foot compared with inner suburbs. Over the last few years the area has seen steady, moderate appreciation; inventory levels fluctuate but suburban demand remains solid for move-in-ready homes. This property is priced to reflect condition and upside: at $410,000 it targets renovators and owner-occupiers who prioritize outdoor space and commuter access. If the market tightens, renovated homes on large lots in this corridor typically perform well — conversely, extended softening in the broader Denver market could compress margins for value-add plays. Overall, this is a compelling buy for an investor or homeowner prepared to invest in updates.
Single-family residential; typical lot coverage and uses consistent with detached homes. Verify with City of Thornton zoning map.
