A vacant lot doesn't have a value until you answer one question first — and it's not 'what are the neighboring lots selling for?'
The question is: what is the highest and best use of this site?
Highest and best use — HBU — is the foundation of every land valuation. It's not about what's on the lot today, or what the owner wants to build. It's the legally permissible, physically possible, financially feasible, and maximally productive use of that site. All four tests. Every time.
Here's where it gets interesting for agents. Two lots on the same street, similar in size, can have wildly different values — not because of what they look like, but because of what they can legally become. A parcel zoned for a single-family residence and a parcel zoned for light commercial don't get compared against each other. They live in completely different markets.
This is why pulling 'land comps' without filtering by zoning and use is one of the fastest ways to end up with a price range that doesn't hold up. The appraiser is going to run this analysis. The agent who already understands it walks into that listing conversation with a completely different level of credibility.
When you're working with vacant land, your first research stop is the zoning map and the municipality's permitted use table — before you pull a single sale. That one step changes everything about how you read the market.
