The record below answers in windows.
The Case
Finished is the case. Owners here never compete with a sales office, never absorb construction traffic and never wait on amenities. The community's variables are all known, which removes the discount uncertainty charges everywhere else in the corridor. Against Avenir's decade of build-out, Sonoma Isles sells certainty.
The preserve edge compounds it. The Loxahatchee boundary does not develop, the lake lots face water that stays quiet, and the DiVosta single level plans match how the largest buyer cohort actually wants to live. Product, boundary and demographics point the same direction.
The Record
The windows below run steady at $497 per square foot with the lake tier recording to $3.2M. Every half year stays active, which for a finished community of this size is the health signal that matters. Dispersion stays modest because the product is consistent.

The Entry Points
The product band is tight, single family from DiVosta's plan set, so entry is about lot line rather than product tier. Interior lots open the community, preserve exposure adds a step, and the lake lots carry the recorded top. The premium ladder is modest, which keeps every entry point liquid.
Single level plans trade best here. The buyer cohort that loves this community shops specifically for them, and the ledger shows those plans clearing fastest.
The Risks
The competition risk is real and local. Avenir sits minutes west with new product at similar money, and some buyers will always choose warranty-new over finished. Appreciation here tracks the family estate segment, so rate moves bite. And market time already runs over two months, slower than the family gates closer to town.
The Hold Math
The hold math is certainty plus boundary. Entry near $2M, known carrying costs, no builder overhang and a preserve line that cannot move. Owners trade the chance of frontier upside for a market whose variables are already on the table, which suits capital that dislikes surprises.
Bottom Line
Sonoma Isles recorded 31 closings in two years as a finished market beside a boundary that cannot develop. The investment case is certainty while the corridor around it builds. Buyers wanting frontier upside have Avenir, and buyers wanting known variables have this gate.
The underwriter's line on Sonoma Isles: pay for the finished certainty, and let the frontier communities test the upside on someone else's capital.

Nothing here is individual investment advice. The figures describe a recorded market, and any purchase decision should weigh personal horizon, carrying costs and the condition of the specific property.
