This whole subject always fascinates me, because it’s a pretty difficult question to answer. Even most appraisers don’t really know what they’re talking about when it comes to valuing land… a vacant lot’s true value is usually a very elusive number to nail down.

Buyers of undeveloped land will have fewer and less attractive financing options through banks than other real estate buyers will. Banks ask for large down payments on undeveloped land and don't offer interest rates as low as those available for new homes. As a result, finding a buyer for your land will be more difficult. If you can afford to offer your own financing, you will open the door to a larger pool of prospective buyers. Hire a lawyer or real estate agent with experience in seller-financed deals to lay out the terms for this type of sale.
Market for Land is Less Active – The market for existing homes is almost always more vibrant than the land market. There simply are fewer numbers of buyers for vacant land than consumers looking for homes. Start marketing a new home listing and a new lot listing when both are desirable and priced well, and you generally can expect fewer contacts about the new lot listing.
