An agreement between buyer and seller is just the beginning of a final transaction.

A simple cash transaction on a piece of vacant land that the seller owns free and clear can be as simple as the seller completing a do it yourself warranty or quitclaim deed and letting the buyer record it. When financing and existing loans enter the picture things can get much more complicated.

A title, abstract, or escrow company or real estate attorney is the best way to go. They can coordinate the entire closing handling the transferring of funds as well as the transfer of ownership. They usually prepare all of the required documents and record them as needed. They also distribute the funds to the appropriate receipients.

Many buyers and lenders will also request "title insurance" to be provided by the seller. A seller can purchase this insurance from the title company at closing. This insurance protects the buyer from any "defects" in the title being given by the seller.
