How to Pull Land Comps

    A practical guide to finding and evaluating comparable sales for vacant land. Learn where to get comp data, how to set search parameters, what makes a good comp, and how to arrive at a reliable value estimate.

    Why Comps Matter for Land Investing

    Comparable sales are the foundation of land pricing. Without comps, you're guessing. With good comps, you can make offers with confidence — knowing what the market actually pays for similar properties.

    The challenge with vacant land is that comps are harder to find and evaluate than for houses. Sales are less frequent, properties are more variable, and the factors that drive value (terrain, access, flood risk) require more research. This guide walks you through the process step by step.

    Where does comp data come from?

    Every property sale is recorded at the county recorder's office. This creates a public record of the sale price, date, and parties involved. Platforms like Zamplo aggregate these records from thousands of counties into a single searchable database, saving you from manual county-by-county research.

    4 Steps to Pull Quality Comps

    Define Your Search Area

    Start with the target property's location. Set a search radius — typically 5 miles in areas with moderate activity, or up to 15 miles in very rural areas. The goal is finding enough relevant comps without going so far that market conditions differ significantly.

    Tips:

    • Start with 5 miles, then expand if needed
    • Stay within the same county when possible
    • Consider natural boundaries (rivers, highways) that may define sub-markets

    Set Your Parameters

    Filter comps by acreage range, date range, and land use to find the most relevant matches. A 10-acre parcel should be compared to similar-sized parcels, not 0.5-acre lots or 100-acre ranches.

    Tips:

    • Set acreage tolerance (e.g., 50% of target size)
    • Use 12-month date range, extend to 24 if needed
    • Match land use code when possible (agricultural, residential, etc.)

    Evaluate Each Comp

    Don't just take an average. Look at each comp individually. Consider how similar it is to your target in terms of access, terrain, location quality, and improvements. Better matches should carry more weight in your final estimate.

    Tips:

    • Check road access and proximity to development
    • Look at terrain/topography via satellite or GIS
    • Note any improvements that affected sale price
    • Consider the comp's position relative to amenities

    Remove Outliers & Estimate

    Remove any comps that seem unusual — family transfers at $1, tax sales, or properties with significant improvements. Calculate your estimate from the remaining comps, adjusting for differences between them and your target.

    Tips:

    • Family transfers often show as $0 or $1 sales
    • Tax sale prices may be well below market
    • Zamplo lets you toggle comps on/off and see the estimate update live

    Common Comp Mistakes to Avoid

    Comparing different property types

    Don't comp vacant land against improved properties (houses, barns). Even a small structure can dramatically change the sale price and skew your analysis.

    Using too wide a search radius

    A comp 30 miles away may be in a completely different market. Stay local unless your area has very few sales, and be aware of sub-market boundaries.

    Ignoring acreage differences

    Price per acre varies significantly with lot size. A 0.5-acre lot at $20,000/acre shouldn't be used to value a 20-acre parcel — the dynamics are completely different.

    Relying on assessed values

    County assessed values are for tax purposes and often bear little resemblance to market value. Always use actual sale prices for comp analysis.
