Conducting a self-closed real estate transaction isn't appropriate for all people and situations. The process DOES require some significant attention to detail and organizational skills. Some people are very good at staying organized and keeping track of these details, and others aren't. Don't try to close your own deals unless you're willing to go slow and get the help you need to ensure you're completing each step in accordance with the laws and regulations of your state.
Access: While few in number, there are still some properties that don’t have legal access – that is, a deeded access-easement, or frontage on a public road. This is what is known as “landlocked” property, and it is of considerably less value. If you see an extremely low-priced piece of land for sale, it may be a bargain, or it may just not have legal access. Curing this can be fairly simple, but don’t count on it. If it were an easy matter, it would likely already have been fixed. In most cases, legal access will require a deed from the neighbor whose land you’re crossing, and folks tend not to like to sign deeds unless they get something of significant value in return.
Closing your own real estate deal doesn't have to be difficult. When I am buying or selling a property with a cash sale (most of my deals are cash transactions these days), it's just a matter of taking the time to ensure that all the documents are completed with the correct information, signed by all appropriate parties and then sent to the appropriate places for recording (the deed should be sent to the county for recording and the supporting documentation should be sent to the local city, township or municipality office for their records).
Next, it’s time to advertise. Depending somewhat on the type and location of your property, you can find a handful of free advertising sites on the web and you should employ these, preferably with a link to your web-page(s) if that’s permitted. However, few of these free sites bring you enough traffic to help much in the absence of some uncommonly good luck.
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!
