do i really need an attorney to close a sale of property

No, however, you should understand that title companies do not represent you for legal matters which often arise. Further, many attorneys are title agents and can provide title insurance and closing services at the same cost as title companies. Attorneys are required to carry malpractice insurance which can serve as a double layer of protection for you and the transaction. Attorney's are cheap insurance for parties in real estate transactions. Also, attorneys can prepare or review your contract. Realtors have no legal duties with respect to drafting contracts.
