While a land transaction is different in many ways from a real estate transaction in which improved property changes hands, it's still a real estate transaction. Land sales still involve escrows and title insurance and are still subject to transfer taxes. As with any other transaction, there are customs for who pays which expense at a closing, but the customs are also set aside when the purchase agreement for the land specifies a different procedure.
The buyer may want to pay to have a policy of title insurance issued on the property subject to the land contract. The buyer can hire a title agency to run a land record search and discover any potential interests attached to the property that may interfere with buyer obtaining a clean title from seller. The parties may agree to split this cost in the land contract agreement.
While approximate land value calculators and charts are available online for most areas of the United States, sellers should use these figures only for broad estimation purposes. Arriving at a more exact price point to use as a listing price is best done by a real estate professional with a solid track record of successfully selling the type of land being sold.
No, the purchase agreement doesn’t need to be notarized – however, in some states (like Michigan, for instance), you technically need to get a witness signature to go along with each party’s signature (the witness doesn’t need to be a notary, it can be pretty much anyone). That being said – there’s nothing “wrong” with getting a notary’s signature on this, it’s just overkill.
I agree with Ellen Chung, finding the right type of buyer to target is very important. Also, you should consider the amount of time you have to sell the land. If you are short on time due to back taxes owed or other financial obligations, your best bet may be to talk to a vacant land investor. You will not get the full market price for your property, but the typically can pay cash and close quickly.
