Now That Highland Homes Got Zoning Approval for 300 More Lots in Aster Park, Will My New Home There Lose Value Before It's Even Finished?

Now that Highland Homes got zoning approval for 300 more lots in Aster Park, will my new home there lose value before it's even finished? Not necessarily - new phases in a growing McKinney community usually affect absorption speed and builder pricing strategy more than they tank existing home values.

If you're under contract or already closed in Aster Park, this kind of news can feel alarming. More lots sounds like more competition, and more competition sounds like lower prices. But the relationship between a new phase and your home's value is more nuanced than that simple math suggests. What matters is where those 300 lots sit relative to your section, what price point and product type Highland Homes plans to build there, and how quickly Collin County's broader demand for new construction is moving right now. A phase expansion can just as easily signal continued builder confidence in the area as it can signal oversupply. The difference usually comes down to timing, location within the community, and how the builder structures pricing and incentives as the new section comes online. This post walks through what a zoning approval for additional lots actually means for your specific home, what historically happens to resale values when a builder expands a community like Aster Park, and the practical steps you can take now to protect your position before your home closes. It's a question worth sitting with carefully rather than reacting to the headline alone.

What the Zoning Approval Actually Means

A zoning or plat approval for 300 additional lots means Highland Homes now has the legal green light to develop more of its land holdings around Aster Park. It does not mean those homes are built, priced, or even on the market yet. There's typically a long runway between approval, infrastructure work, model home construction, and actual sales releases.

In practice, this kind of approval is a signal of builder confidence in the McKinney submarket, not a red flag. Builders don't request more lots in a community where they expect demand to dry up. They request them because absorption in the earlier phases has been strong enough to justify expansion.

Why More Lots Doesn't Automatically Mean Lower Prices

It's a common assumption that more inventory equals falling prices, but new-home pricing and resale pricing don't move in lockstep the way it might seem.

• Builders typically raise prices in each new phase to reflect rising land and construction costs, not lower them.
• New sections are often built with updated floor plans, larger lots, or different price tiers that don't directly compete with your home's specific product type.
• Collin County has continued to see steady population growth, which gives builders room to add supply without flooding the market.

Where you do need to pay attention is incentive structure. If Highland Homes starts offering aggressive rate buydowns or price cuts on the new phase to keep sales moving, that can create a comparison problem for anyone reselling an existing Aster Park home in the near term, even if your home's fundamental value hasn't changed.

What Could Actually Pressure Your Value

The real risk isn't the lot count itself - it's how the builder manages pricing and pace during the transition. A few scenarios worth watching:

• Aggressive builder incentives: If new-phase homes come with heavy incentives, appraisers may use those sales as comparables, which can soften resale pricing for existing owners.
• Extended construction timelines: Ongoing construction traffic, dust, and partially built streets can be a short-term annoyance that affects how quickly resale listings move, even if it doesn't change long-term value.
• Overlapping product types: If the new 300 lots target a similar buyer and price range as your section, you may see more direct competition for buyers once both phases are selling simultaneously.

This is a similar dynamic to what's playing out elsewhere in the McKinney area. If you're weighing how new product near an existing community affects resale, it's worth reading our take on whether a new development near Trinity Falls and Painted Tree drags down resale value, since the underlying logic applies here too.

How Location Within Aster Park Matters

Not every section of a McKinney master-planned community is affected equally by a new phase. Homes closest to the new construction zone may deal with more short-term noise and traffic, while homes in established, amenity-adjacent sections of Aster Park often hold their appeal regardless of what's being built a few streets over.

If your home backs up to or sits directly adjacent to the planned expansion, it's worth asking Highland Homes for a site plan showing exactly where the 300 lots will go, what product type is planned, and the expected timeline. That information tells you far more about your specific risk than the headline number of 300 lots does.

How to Protect Your Position Before Closing

If you're still under contract on a to-be-built home in Aster Park, there are a few things you can do now:

• Ask your builder rep directly about the planned price point and incentive strategy for the new phase.
• Review your contract's completion timeline and any protections tied to delays.
• Get a clear picture of how your lot's location compares to where the new 300 lots will sit.
• Track recent closed sales in Aster Park and nearby McKinney communities to see how pricing has actually trended, rather than relying on assumptions.

None of this requires panic. It requires information, and that's something an agent who tracks Collin County new-construction activity closely can pull together for you quickly.

The Bigger Picture for Collin County Buyers

Aster Park is one of several McKinney communities seeing continued builder investment, which generally reflects well on the broader area rather than signaling a slowdown. Builder expansion is a normal part of how master-planned communities mature, and most buyers who hold their homes for several years see values track with the overall McKinney and Collin County market rather than with any single phase announcement.

Frequently Asked Questions

Does a new phase of a community always lower existing home values?

No. New phases often reflect strong builder confidence and can come with higher prices per square foot as construction costs rise, though aggressive incentives in the new phase can affect short-term resale comparables.

How can I find out exactly where Highland Homes plans to build the new 300 lots?

Ask your builder sales rep for the updated community site plan, or request a copy through the City of McKinney's planning department records tied to the zoning approval.

Should I delay closing on my Aster Park home until the new phase details are clearer?

Usually not necessary. It's better to gather specific information about the new phase's location and pricing strategy and factor that into your decision rather than delaying a closing you've already committed to.
