Advice: One of the added benefits of hiring this agent is that they can advise you on much more than just the price of your land. A true professional will have a network of individuals that can help you with anything from tax planning to pond building. An experienced agent can tell you what is possible. They may know many things that can save or make you money during your transaction. Most of the time a good agent will help you net more money from selling your property than you can get on your own.
A really rough guideline that alot of spot-lot developers use is that the land should be somewhere between 10 and 15% of the sales price of the home. So, if the homes on ten acres were selling for $1 million, the developers were likely paying $100-150k for the lots. The home on your lot would likely sell for substantially less given the smaller lot size, so expect less for the land 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.
