chattels: items that are not fixed to the land or building structure e.g. fridges and are only included if specifically mentioned in the sale and purchase agreement. If chattels are included in the sale, they should be listed in detail in the sale contract. Some standard sales and purchase agreements included common chattels such as stove, fixed floor coverings, blinds and curtains.
Land buyers are going to be more interested in a property that’s in the right location than one that’s more far-flung. For example, a buyer looking to build up a housing development might be more interested in land that’s near the Kansas City metro area, as the houses built on that land will be more likely to attract buyers, especially buyers who work in the metro area.
There always seems to be an endless pile of paperwork and a lot of legal hoops to jump through (everybody wants to protect themselves from liability, etc). While some of this documentation is certainly good practice – I've learned that when you boil it all down, closing a real estate transaction is actually a fairly simple process – especially when it's an all-cash transaction (no financing or mortgages involved).
You can also look to certain companies and organizations that have a concentration of people that may fall in the above mentioned roles such as investment companies (i.e. Charles Schwab, Fidelity), financial advising companies (i.e. Morgan Stanley, Merrill Lynch). There may be a higher concentration of people who can both afford and want to build their own custom homes or to build income-producing properties. Try linking yourself to financial advisors who may already know of people who have these types of dreams. This isn't a comprehensive answer of all the possibilities but just some thoughts. Good luck!
