Many factors dictate how much an acre sells for in and around Kodiak. There is no set price, but a good indicator is the assesed value. There are two parcels that are 8 acres and they are selling for about $15,625/acre, a pretty good price. The one property with a house on it, priced at $169,000, has an assessed land value of about $16,500.
As with any market, the true method to determine a price is the offer. If a buyer makes an offer of $10,000/acre and the seller accepts that offer, then that is the price of an acre.
Hope this helps! Feel free to call me at (907) 486-4663 to discuss this further.
