Blue Knoll
Homes for Sale in Middleburg, FL
True comps, carrying-cost math, and listings before the portals.
Blue Knoll is a small, established pocket of Middleburg with 58 homes and a build span running from 1973 to 2021. That range tells you the most about price here: this is a condition-and-vintage market, not a uniform tract. The older stock and the newer infill will not trade on the same terms, so what sets value is the individual house — updates, systems, and lot — far more than any neighborhood-wide figure.
With a median living area around 1,568 square feet, these are right-sized homes rather than sprawling ones. Buyers should underwrite each property on its own merits and read condition carefully, since the spread between a dated original and a renovated one can be wide. Sellers should expect scrutiny on updates; a well-maintained or recently improved home is the one that separates itself in a community this varied.
The 60-Second Overview
Blue Knoll is a compact Clay County community where roughly half the homes are homesteaded, a sign of an owner-occupied core rather than a churn of rentals. The mix of vintages, from early-1970s to recent construction, means no two comps look quite alike.
Pre-construction details are compiled from public records, builder announcements and builder listings, and are subject to change without notice; figures are deemed reliable but not guaranteed. Momentum Research figures are our own analysis. This page describes homes, pricing and community attributes, not residents.
Who Blue Knoll is best for.
Best for
- Buyers targeting a right-sized home around 1,568 square feet who prioritize location over square footage
- Buyers open to an older home they can update, or a newer one at a premium, and willing to price for condition

Probably not for
- Buyers who need a large selection of near-identical homes and tidy comps
- Buyers wanting only new construction with no interest in older vintages
- Investors expecting a deep, fast-moving rental inventory in a small owner-occupied community

The Blue Knoll buying strategy.
If we were buying in Blue Knoll today, this is the order of operations we would run for our clients.
Underwrite the condition first. Price the roof, HVAC, and systems honestly before judging any list price; condition swings value here more than square footage alone.
Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.
Move deliberately, not desperately. Neither side has a decisive edge, so a well-prepared, fairly-priced offer wins without overpaying.
Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.
Keep an agent in your corner. The listing agent works for the seller; we represent you and prepare a hand-built valuation before any offer in Blue Knoll.
A mixed-vintage pocket that rewards a close look
The defining feature is age diversity. A build range from 1973 to 2021 inside just 58 homes means you can tour an original 1970s house and a home from the last few years in the same afternoon. That variety is an opportunity for a buyer willing to match budget to condition, but it makes broad pricing generalizations useless — you value the specific house.
A homestead share of 54% points to an owner-occupied backbone, which typically shows up in maintenance and continuity of ownership. For sellers, that stability can mean thinner inventory at any given moment; for buyers, it means moving decisively when the right vintage and condition come available, because comparable listings do not appear every week in a community this size.
The location and the amenities are priced into every listing in Blue Knoll. The deal is won or lost on condition, the comps, and the renovation math.
