With the example inputs shown above, the model gives comparable-based land value: $246,667.
The formula is comparable price per acre × subject acres. Open the breakdown to trace expenses and assumptions. Change one input at a time to see how your decision changes. This example uses scenario inputs; it is not an offer, tax bill, appraisal or legal determination.
Normalize comparable land sales
Divide each closed sale price by its acreage, average those prices per acre and multiply by the subject acreage. The low and high scenarios use the lowest and highest unit prices entered. This is a transparent screening method rather than an appraisal. Parcel-size discounts can make a simple proportional comparison unreliable when sizes differ greatly.
Usability can matter more than total acres
Road access, utility availability, zoning, topography, flood risk, wetlands and permitted use can dominate land value. A parcel with a high proportion of unusable area should not be compared mechanically with a fully usable one. This tool accepts your selected comps; it does not discover restrictions or adjust automatically for them.
Build a defensible range
Favor recent arm’s-length sales with similar legal use and infrastructure. Separate entitled development land from raw agricultural or recreational land. Confirm whether the reported acreage and sale price include improvements. Review the spread in the table and investigate outliers before relying on the average in an offer.
