AcreValue is a website that lists information submitted by real estate brokers for land across the US. The interactive map shows Parcels, Common Land Units (CLUs), Land for Sale, Sold Land. You can search by town, county, or address. If you are looking for sold land to see actual sales prices, you can limit searches to that category.
Introduced by Granular, [a software and data science tools for growers] in April 2015, AcreValue is used by farmers, landowners, investors, bankers, brokers, and industry professionals to analyze the value and productive capacity of farmland and to research and transact more efficiently.
AcreValue Land Prices
As with all such tools, AcreValue land prices are educational. The listings are unlikely to list all land for sale and some may be already sold. But it is a good tool for learning how people talk about land (vocabulary again). It provides a realistic measure of how land is sold and what may be available for how much where. And very useful, you can compare one state or region with another.
It is particularly helpful to have prices listed so you begin to look at price realistically.
Developers inform me that many pieces of land are not announced to the public. Local networks of professionals carry information to business realtors, architects, developers, etc. In the end, you will have to connect locally for a real land search.
