O'Neil Property Group
An active custom-build community southwest of Newark — one-acre-plus lots recently selling in the $40Ks and $50Ks, with recorded covenants but no association fees, in Sandwich school territory.
Silver Fox Estates is where the Newark area’s build-your-own market is most active right now. Platted across the N 4459th Road and E 2969th–2979th Road grid southwest of the village — LaSalle County’s Northville Township, with Newark 60541 mailing addresses — the community offers one-acre-plus build-ready lots that have been trading steadily in the $40Ks and $50Ks, with a half-dozen sold in spring 2026 alone and several more actively listed.
The framework is recorded covenants without an association: minimum 1,700 square feet for a ranch, 2,100 for a two-story, outbuildings capped at 1,000 square feet, no mobile homes — quality floors that protect your investment without a monthly fee or an architectural committee to satisfy. Homes are on private well and septic, and the handful of existing builds from the 2005–2012 era run roughly 2,250 to 3,130 square feet on one to one-and-a-half acres.
One important note for buyers comparing this community against acreage closer to the village: Silver Fox Estates sits in Sandwich CUSD 430 for schools, not Newark 66/18, despite the Newark address — a district assignment worth confirming parcel by parcel. Finished-home comps inside the community are thin (a spring 2026 resale is the only recent data point), so we lean on build cost plus lot value when advising on what a completed project here is worth.
Pricing reflects Silver Fox Estates sales and active listings as of mid-2026.
The active market: one-acre-plus parcels with recent sales from $41.9K to $59.9K (spring 2026) and several currently listed in the $50Ks. Covenant minimums set the quality floor for what gets built around you.
See listings →A small set of 2005–2012 builds — three- and four-bed customs on 1–1.5 acres. Resales are rare; a single recent sale (spring 2026) is the only current comp, so valuations here lean on replacement cost.
See listings →With lots under $60K, most finished projects land in the range where the area’s established acreage customs trade — a build math that has stopped working in most of Kendall County.

Recorded covenants protect the streetscape — build minimums, outbuilding caps, no mobile homes — while leaving you free on builder, timeline, and design. No association fees, ever.
One to one-and-a-half acre parcels on a quiet township road grid, surrounded by working farmland — the open-country setting buyers picture when they say they want to leave the subdivisions.
