Land that looks identical frequently is not. The differences that matter most are legal, physical and regulatory rather than visual.
Access and frontage
How wide the frontage is, whether access is legally recorded, and whether a vehicle can reach the site all change what can be built and who can buy.
What is permitted
Zoning, permitted use and building limits set what a buyer can do with the land. Two blocks with different permissions are two different products.
Ground conditions and services
Flood risk, soil condition, level relative to the road, and the availability of water, power and drainage all carry a real cost to resolve — and that cost comes off the price.
