Answer: Civil Rights Act of 1866, Jones v. Mayer.
Explanation:
Under the Civil Rights Act of 1866 and Jones v. Mayer (1968) any discrimination based on race when selling or leasing properties is prohibited. In Jones v. Alfred H. Mayer Co. (1968) it was held that Congress would control the sale of private property to stop racial discrimination. The foundation for that decision was the Civil Rights Act of 1866.
