Why shop with your own buyer agent

Many buyers walk into a builder sales office alone. That counselor works for the builder. Your own agent works for you — comparing communities, reviewing contracts, and helping you negotiate upgrades, closing costs, and timing.

  • On most new builds, builders still commonly pay a buyer-agent commission under their co-op policy — so having representation often does not cost you extra out of pocket. Always confirm the current co-op offer for the specific home and community before you register.
  • Bring your agent on the first visit. Many builders require registration at first contact; if you register alone, it can be harder to add representation later.
  • A local agent who already tracks Aster Park and Grayson County week to week can show you both builder inventory and recent resales so you are not comparing only to the model home.

Prices and status change; confirm with the listing or builder before you write an offer. Per-sq-ft figures are approximate.

Home Builder / type Price Beds / baths Sq ft $ / sq ft School Ready Notes
6808 Tadpole Trail Shaddock QMI $799,000 4 / 4 3,682 ~$217 Prosper ISD Available Burnet plan; media room; no MUD/PID
7212 Dasher Drive Ashton Woods QMI $735,000 5 / 4.5 3,908 ~$188 Celina ISD Available now Westbrook plan; price reduced; 3-car garage
7213 Oak Knoll Dr William Ryan QMI $769,990 4 / 4.5 3,366 ~$229 Prosper ISD Est. Feb 2027 Shenandoah II w/ media room; 3-car
7409 Victory Court (Lavon) Toll Brothers QMI $899,000 5 / 5.5 3,686 ~$244 Prosper ISD Move-in ready Closest size match among Toll QMIs; Toll Aster Park QMIs roughly $769K–$949K

Takeaway for many Prosper ISD shoppers: 6817 Tadpole is move-in ready on a larger corner lot with upgrades already done, at a lower total price than the Toll Brothers Lavon and roughly even with Shaddock next door — while Dasher at $735K trades into Celina ISD and a different lot story.

Incentives change and carry lender, credit, and loan-type limits. Treat every advertised rate as an estimate until your lender issues a Loan Estimate.

Monthly payment estimator

Compare a resale (optional seller credit) against a builder home (optional closing-cost credit or buydown). Principal & interest only — estimates, not a loan offer.

Option A — often a resale

Effective price after credit: $797,000
Est. monthly P&I:
$0

Option B — often a builder QMI

Effective price after credit: $715,000
Est. monthly P&I:
$0
Read the rate type A 3.99% builder promo may be a temporary buydown or an adjustable-rate loan (for example Ashton Woods’ 7/6 ARM). After the intro period, the payment can rise. Ask your lender for the fully indexed payment and lifetime cap before you choose on payment alone.

Does not include taxes, insurance, HOA, mortgage insurance, or ARM adjustments after the initial period.

Questions to ask before you walk into a builder’s sales office

  1. Bring your own agent on the first visit
    Many builders require you to register at first contact. Arrive with your buyer agent so representation is clear from day one.
  2. Confirm school district by address
    Aster Park has homes in Prosper ISD and some in Celina ISD (for example 7212 Dasher). Zoning can differ lot to lot — verify with the district before you fall in love with a floor plan.
  3. Compare lot size and orientation, not just the model
    Corner lots, greenbelt backs, and larger acreage (like the 0.193-acre corner at 6817 Tadpole) change how the same square footage lives day to day.
  4. Ask what is included vs. upgrade pricing
    On a resale, upgrades like whole-home water filtration, kitchen reverse osmosis, epoxy garage floors, and fencing may already be done. On a new build, those are often design-center extras.
  5. Get the real completion and close date in writing
    Quick move-ins and “ready Feb 2027” homes are not the same timeline. If you need to be in by the holidays, prioritize completed inventory.
  6. Still get a third-party inspection on new construction
    A builder warranty is not a substitute for an independent inspection before closing — and again before the warranty window ends.
  7. Read the incentive fine print with your lender
    Preferred-lender requirements, credit-score floors, ARM vs. fixed, and contribution limits all affect whether the advertised payment is the payment you keep.

Growing into Grayson County

North of McKinney along US-75, Grayson County (Sherman, Denison, Van Alstyne, Gunter, Howe, Pottsboro) is drawing buyers who want newer homes, more land, or a shorter drive to Lake Texoma — often at a lower entry price than Collin County.

A major reason: semiconductor investment in Sherman. Texas Instruments describes a potential up to $40 billion investment for up to four connected 300mm wafer fabs (SM1–SM4); SM1 is in production, and SM2’s exterior shell is complete, with later fabs tied to demand (ti.com Sherman manufacturing). Nearby, GlobalWafers’ GlobiTech silicon wafer facility in Sherman opened Phase 1 in 2025 (roughly a multi-billion-dollar campus), with additional phases planned as customer demand supports them.

Notable new-construction communities

Community City From (builder) Schools Why buyers look
Bel Air Village (Chesmar) Sherman From $274,990 Sherman ISD Attainable price point closer to the fabs; amenities and parks
Heritage Ranch (Highland) Sherman 40-ft lots from the $290s; 50-ft from the $320s Sherman ISD Master plan near US-75; parks, trails, ponds
Mantua / Mantua Point (Highland & others) Van Alstyne Highland 40-ft from the $340s; 55-ft from the $430s; 75-ft from the $610s Van Alstyne ISD ~2,000-acre master plan ~10 miles north of McKinney; trails, lakes, resort amenities
Gateway Village – The Reserve (Highland) Denison Advertised from the $370s (40-ft) / $400s (50-ft) on Highland-area guides — confirm live pricing with Highland Denison ISD Wooded / greenbelt feel near Lake Texoma

Starting prices move with phases and incentives. Christyne will pull current inventory, incentives, HOA/MUD/PID, and school zoning for any community you shortlist.

Land & lots: Glen Ellen, Pottsboro

Christyne lives in the Glen Ellen neighborhood of Pottsboro — Grayson County, minutes from Lake Texoma. If you want to build a custom home near the water (marinas, Tanglewood, weekend lake life) instead of buying a production floor plan, she is the neighbor who already knows the streets, utilities questions, and what recent lots have asked.

In Woods on Glen Ellen Phase III, several roughly 1-acre homesites are actively listed as of early November 2026 in about the mid-$100,000s to mid-$200,000s. Verified examples include listings around $175,000 to $235,000 (for example 75 S Crescent Dr and Meadow Lane homesites). Phase III is described by listing copy as a boutique section with a limited number of estate-style homesites; availability changes weekly.

  • Bring your own builder (or ask Christyne for introductions) and review HOA, plat, and utility requirements before you write an offer.
  • Confirm Pottsboro ISD zoning and any view or waterfront claims on the specific lot — aerial photos are not a survey or a guaranteed lake view.
  • Use the form below and choose Lots / land if you want a short list of current Glen Ellen and nearby Texoma lots.
