Rim Rock, Parten & Reunion Ranch

Three communities, one corridor

Southwest of Austin, in the wedge of Hays County between US 290 and the Driftwood crossroads, three communities answer the same buyer brief — Dripping Springs ISD, space, quiet — in three different ways. Rim Rock, off FM 967, is the established one: custom homes on one to two-plus acres, building since 2007. Parten, off RM 1826 south of Nutty Brown Road, is the new one: a 532-acre master plan actively building luxury production homes. Reunion Ranch, farther down 1826 toward the SH 45 end, sits between them: 437 homes built by a single builder from 2012 to 2022 on quarter-to-0.8-acre lots, now a young resale market. They’re minutes apart on the map and meaningfully different on the closing statement, so we cover them as one decision.

The shared setting is the point: this is genuine edge-of-the-Hill-Country living, where Driftwood’s wineries and the Salt Lick’s smoke are the local landmarks and the night sky still performs. It’s more buttoned-up than raw Driftwood acreage — these are platted communities with HOAs and paved streets — but far looser than the sidewalk suburbia of Belterra fifteen minutes north.

Rim Rock: the acre standard

Rim Rock is what most people picture when they say “an acre in Dripping Springs ISD.” Lots run one to two-plus acres, homes are custom and semi-custom — mostly limestone-and-stucco single stories and low-slung two stories from 2007 onward — and the community threads six-plus miles of nature trails between them. Per Redfin public market data, mid-2026 (verify current), homes generally sell in the $850K–$1.6M+ range, with view and newer-build properties at the top; the occasional remaining lot lists in the $300Ks.

The honest file: this is light-rural ownership. Homes sit on septic, irrigation on an acre is a real line item, and the earliest sections are pushing twenty years old, which means roofs and mechanicals on the inspection docket. In exchange, Rim Rock carries the leanest tax stack of the three — no meaningful district debt — typically landing in the 1.6–1.9% effective range (verify per parcel). For long-haul cost of ownership, that spread compounds.

Parten: the new build

Parten is the corridor’s active construction story — rolling former ranchland off 1826 with production-luxury homes on 65-, 75-, and 85-foot lots plus a section of larger homesites, planned for several hundred homes at buildout. Builder-published pricing in mid-2026 runs roughly $800K to $1.2M+ (verify current releases). The appeal is obvious: new mechanicals, current floor plans, warranty coverage, and DSISD, without taking on acreage maintenance.

The tradeoffs are just as plain. Lots are suburban-scaled — you’re buying the setting, not land of your own — and the community will live with builder traffic, model homes, and sapling-stage landscaping for years. New communities here also carry special-district or similar infrastructure financing that pushes the tax stack above Rim Rock’s; the exact rate varies by section and year, so we pull the current sheet on any specific lot before a client signs. If you’re weighing Parten, it’s worth also touring Headwaters and Caliterra toward Dripping Springs proper — same district, different amenity philosophies.

Reunion Ranch: the middle path

Reunion Ranch splits the difference. Built out between 2012 and 2022, it offers newer-vintage homes — roughly 2,200 to 5,400 square feet — on lots from a quarter acre to 0.8, with a gated pool, pavilion, sports courts, and trails. Because one builder developed the whole community, the streetscapes are cohesive and the resale market is easy to read: per public market data, mid-2026, homes generally sell from the $800Ks to $1.5M (verify current). You get most of Parten’s newness without construction-phase living, and more land than Parten offers — though not Rim Rock’s acres. It too carries district financing; verify the parcel’s stack, because it changes the monthly more than most buyers expect.

Schools, taxes, and the practical file

All three communities feed Dripping Springs ISD, one of the region’s strongest districts. The general pattern runs through the Sycamore Springs elementary and middle campuses on Sawyer Ranch Road — with Reunion Ranch assigned to Cypress Springs Elementary — and everyone converges on Dripping Springs High. The district rezoned effective 2025–26 as it grows, so treat any listing’s school line as a claim to verify, not a fact.

On taxes, the corridor’s rule of thumb: the newer the infrastructure, the bigger the stack. Rim Rock typically runs ~1.6–1.9% effective; Parten and Reunion Ranch trend higher — toward the low 2s — because of district debt (all figures before exemptions; verify per parcel and year). Add each community’s HOA and, in Rim Rock’s case, septic maintenance, and the “cheapest” option depends entirely on which home you’re comparing.

Getting around, and who each fits

Downtown Austin runs 35–55 minutes — FM 1826 north to 290 East, or 45/MoPac from the Reunion Ranch end — and the airport about 45. Groceries mean the Nutty Brown H-E-B (10–15 minutes for Parten and Rim Rock) or Kyle’s big-box row from Reunion Ranch. There is no shortcut, and weekend winery traffic on 1826 is real.

Our shorthand: Rim Rock for the buyer who wants land and low carrying costs and will happily own a septic system; Parten for the buyer who wants a warranty and current finishes and accepts a construction-phase community; Reunion Ranch for the one who wants newish and settled at once. We tour clients through all three in an afternoon — the corridor makes the differences obvious in person faster than any spreadsheet does.
