Land for sale in Collin County, TX — the fastest-growing land market in DFW
Collin County is the headline growth story of North Texas — the second-fastest-growing county in the United States in 2025, home to the nation's fastest-growing city (Princeton), and anchor of the US-380 corridor that has driven institutional land investment from Toyota, JPMorgan, and a generation of master-planned community developers. Collin is also the most expensive land county in the BuyDirtTX coverage area.
Overview
Collin County sits directly north of Dallas, with Plano, Frisco, McKinney, and Allen anchored along the US-75 spine. The county added approximately 43,000 residents in the year ending July 2025 — second only to Harris County nationally — bringing the population to nearly 1.3 million.
Land economics follow the development front. Anything inside the 380 loop (Frisco, Prosper, Celina, McKinney) is priced for entitlement, master-planned community pressure, and institutional development capital. The eastern tier — Farmersville, Blue Ridge, and Princeton — still trades at working-ranch prices but is being absorbed quickly. Princeton's population grew over 30% from 2023 to 2024 alone, the fastest growth of any city in the United States.
Per the Texas Demographic Center, Collin County is projected to exceed 1.4 million residents by 2030 and 1.7 million by 2040. The macro thesis here is not in dispute — the question is what tract, in what sub-market, on what timeline.
Price Corridors
Collin County breaks cleanly into four sub-markets with very different price profiles and buyer types.

Land Types
Development / Hold
Raw acreage in the direct path of growth along the US-380 corridor. Master-planned community developers, regional homebuilders, and institutional investors actively assembling tracts. 3–7 year horizon for the 380 zone; longer for east Collin.
Investment / Long Hold
East Collin County (Farmersville, Blue Ridge, Princeton, Anna) ag-exempt working land in the path of the next development wave. 5–10 year thesis but the lowest entry prices in the county.
Lake Lavon Recreational
Waterfront, near-water, and Corps-adjacent land on the 21,400-acre USACE reservoir. Lifestyle and recreational demand.
Estate / Ranchette
5–25 acre lifestyle tracts in Parker, Lucas, Fairview, and northern Collin. Custom home estates with significant premium for elevation, water features, and ISD assignment.
Equestrian
Established equestrian tradition in Parker, Lucas, and eastern Collin. Horse properties with arenas, barns, and cross-fencing serve a dedicated buyer community.
Zoning & ETJ
Collin County has minimal county-level zoning in unincorporated areas. The binding constraints are city zoning ordinances and ETJs — and in Collin County, those ETJs are aggressive and constantly expanding.
Water & Utilities
Collin County has three water options that vary significantly by location.
Ag Exemptions
Ag exemption is the single largest tax lever on raw land in Collin County — often the difference between $300/year and $25,000+/year on a 50-acre tract along US-380.
Investment
Collin County is the most institutional land market in North Texas — strong fundamentals, intense competition, and very few buyers under-pricing risk.
If you can buy east and hold five-plus years, Collin remains the highest-conviction land trade in North Texas. The 380 corridor is priced for execution and rewards developers and institutional buyers, not patient investors. The eastern tier offers the same thesis with a longer timeline and a more accessible entry.
Growth Outlook
The development front continues to push east and north at approximately 1.5 miles per year. Farmersville and Blue Ridge in 2025 are functionally what Princeton was in 2020 — small towns that the major builders are beginning to take seriously. Princeton itself is now actively absorbing master-planned community capital with the fastest residential growth rate of any U.S. city.
Watch the Outer Loop and SH-5 expansion projects — both will reset land values within a 3-mile radius of new interchange points. The completed 380 widening from Frisco eastward has already produced visible appreciation along its corridor.
Lake Lavon recreational land has a permanent supply constraint from the Corps of Engineers boundary. That constraint becomes more valuable as the surrounding county urbanizes — recreational acreage within 30 minutes of a 1.3 million-person county is a different asset than the same land 20 years ago.

FAQ
Only in the far eastern tier — Farmersville, Blue Ridge, Anna, and the rural areas south of Princeton. Anything inside the 380 loop or in the McKinney/Frisco/Celina footprint now starts at $80K–$100K/acre for serious tracts.
Three factors stacked. The Plano corporate HQ cluster (Toyota, Liberty Mutual, JPMorgan) drives high-income housing demand. The US-380 master-planned community wave drives near-term residential development. Texas Demographic Center projections call for the county to double again by 2060.
30–45 days for raw land. Push for 60 if septic, well, floodplain, or entitlement work is in play. ETJ verification can extend timelines because city responses vary.
Always. Category 1A survey, $1,500–$4,000 — the cheapest insurance you'll buy in this market.
Routinely severed. Always confirm what conveys with the surface estate before closing.
Five of the last seven years of qualifying use per CCAD. Plan in years, not months. Don't buy ag-exempt land assuming you can convert use without breaking the exemption.
