How Much is 1 Acre of Land in Washington?

Washington's land market for small parcels (0-2 acres) is a tale of two vastly different regions, defined by the Cascade Mountain Range. Our analysis of sales data from across the state's 39 counties shows an immense price premium for land in the populous Puget Sound region compared to the more arid and rural counties of Eastern Washington.

Key insights from our 0-2 acre data:

• Puget Sound Premium: Proximity to Seattle and the desirable waters of the Puget Sound creates the most expensive market in the state. King County ($650,000 per acre) and San Juan County ($450,000), known for its scenic islands, have the highest median prices by a wide margin.
• Eastern Washington Value: The most affordable land is found east of the Cascades. Ferry County ($15,000 per acre), Lincoln County ($16,875), and Pend Oreille County ($18,750) offer the lowest median prices for small parcels in the state.
• A Clear Divide: The data highlights a clear geographical split. Counties west of the Cascades, like Snohomish ($250,000) and Pierce ($175,000), maintain high values, while counties in the central and eastern parts of the state offer significantly more affordability.
• Development Drives Price: For these small lots, the primary driver of value is their potential for home building, making their prices a key indicator of local residential demand and growth.

The table below provides a comprehensive, county-by-county look at the current median per-acre prices for small lots across the state of Washington. This data can be very useful if you're looking to sell land fast in Washington.

How Much is 5 Acres of Land in Washington?

In the popular 2-5 acre range, the Washington land market provides more space for a lower per-acre cost, but the dominant market trends remain firmly in place. These "hobby" sized parcels are ideal for those seeking privacy and room to spread out, and the data shows a clear premium for land west of the Cascade Mountains.

Key insights from our 2-5 acre data:

• Puget Sound Still King: The counties in the Seattle metro area and the San Juan Islands continue to command the highest prices. King County leads the state with a median price of $350,000 per acre, followed by San Juan County at $250,000.
• Price Moderation is Key: While still the most expensive, the per-acre prices in these top-tier counties have dropped significantly from the 0-2 acre bracket. This is a typical market dynamic that increases buying power for those seeking slightly larger properties.
• Eastern Washington's Value: The most affordable 5-acre parcels are found east of the mountains. Ferry County has the lowest median price in the state at just $11,250 per acre, with Lincoln ($13,125) and Pend Oreille ($15,000) counties also offering excellent value.
• The Cascade Divide: The price gap between the wet, populous western side of the state and the dry, rural eastern side is the single most defining feature of Washington's land market.

How Much is 20 Acres of Land in Washington?

In the 10-20 acre category, the Washington land market offers substantial space for farming, recreation, or a sizable private homestead. The per-acre prices in this range are significantly more affordable, yet the market is still clearly divided by the Cascade Mountains, with western counties commanding a premium.

Key insights from our 10-20 acre data:

• Puget Sound's High Demand: The Seattle metropolitan area continues to have the most expensive land. King County leads with a median price of $93,750 per acre, followed by Snohomish County at $75,000 and Clark County in the Portland metro area at $60,000.

Ferry County offers the lowest median price at just $6,563 per acre, with Lincoln ($7,500) and Pend Oreille ($8,438) counties also providing excellent value.
• Land Use Becomes Critical: At this size, the utility of the land is a primary driver of value. A 20-acre parcel of flat, usable pasture will be priced very differently than 20 acres of steep, rocky, or inaccessible terrain.

How Much is 100 Acres of Land in Washington?

To analyze the market for large-acreage properties, like 100 acres, we must look at a broader range of sales to create a reliable data set. For this final section, we've grouped sales between 20 and 100 acres. It’s important for readers to understand that the per-acre price for a 25-acre property can differ significantly from that of a 95-acre parcel, even within the same county. However, this approach provides the most accurate and stable overview of the market for large tracts of land in Washington.

Key insights from our 20-100 acre data:

• The Puget Sound Premium Endures: Even at this larger scale, the counties in the Seattle metro area hold the highest values. King County leads the state with a median price of $52,500 per acre, followed by Snohomish County at $45,000 and Clark County at $37,500.
• Unbeatable Value in Eastern Washington: For buyers seeking the most land for their investment, the rural counties east of the Cascades are the clear winners. Ferry County has the lowest median price in the state at just $5,063 per acre, with Lincoln ($5,625) and Stevens ($6,563) counties also offering exceptional affordability.
• Land's Purpose is Key: At this size, the utility of the property is paramount. One hundred acres of productive farmland in the Palouse is a vastly different asset than 100 acres of remote, rugged timberland in the mountains, and the market price will reflect that.

The table below provides the complete, county-by-county data for 20-100 acre parcels, offering a valuable baseline for understanding large-acreage land values across the Evergreen State.
