What is an Infill Lot?
An infill lot is a vacant or underutilized parcel of land within an established, built-up area. Unlike raw land on the urban fringe, infill lots are surrounded by existing development and have access to established infrastructure: roads, utilities (water, sewer, electricity, gas), schools, shopping, and public services. This makes them ready for development without the infrastructure costs associated with greenfield sites.
Infill lots command premium prices because they offer developers immediate buildability in established neighborhoods with proven demand. A vacant lot in a desirable subdivision where existing homes sell for $400,000-$500,000 might be worth $80,000-$150,000, while a comparable-sized parcel of raw land 20 miles away might sell for $5,000-$15,000.
How infill lots are created
Infill lots exist for various reasons: a previous structure was demolished and not replaced, a lot was skipped during original development, a larger parcel was subdivided, or zoning changes made a previously unbuildable lot developable. Some investors specialize in finding and assembling infill lots, particularly in gentrifying neighborhoods where older, dilapidated structures can be demolished and replaced with new construction.
Infill development considerations
Zoning and setback requirements may be more restrictive in established areas. Neighbors may oppose new construction. Utility connections may need upgrading if the original infrastructure is old. Building codes for new construction are stricter than what existing homes were built under. And construction access can be challenging in tightly built neighborhoods.
Infill lots and investors
For builders and flip investors, infill lots represent new construction opportunities in areas where land is scarce and demand is high. The combination of a new-build home in an established neighborhood often commands the highest prices per square foot. For wholesalers, infill lots can be marketed to builders and developers who are always looking for buildable parcels in active markets.
