Final answer:
The exemption from the Federal Fair Housing Act applies to the sale by an owner of their single-family residence when no discriminatory advertising is used, and no real estate agent is involved.
Step-by-step explanation:
The question relates to exemptions from the Federal Fair Housing Act of 1968, which strives to eliminate discrimination in the sale or rental of housing. One of the specific situations provided in the question that is exempt from the Act is the sale by an owner of the owner's current single-family residence, under two conditions: no discriminatory advertising is used, and no broker or real estate agent is involved in the transaction. This type of sale falls under the "private sale" exemption of the Fair Housing Act, intended to give homeowners selling their own property more freedom in choosing to whom they sell their home, as long as no discriminatory practices are publicly advertised.
