A homeowner who refuses to sell their home based on the buyer having children is violating what law?

The correct answer is the Fair Housing Act. This federal law was enacted in 1968 to eliminate discrimination in housing based on race, color, national origin, religion, sex, familial status, and disability. Familial status specifically protects individuals who have children under the age of 18. Therefore, if a homeowner refuses to sell their home because the buyer has children, they are in violation of the Fair Housing Act as they are discriminating against a protected class based on familial status.

The other options do not address this specific type of discrimination. The Residential Sales Act primarily deals with the regulations surrounding the sale of residential properties and doesn’t encompass discrimination based on familial status. The Equal Opportunity Act is more of a general term that could refer to various regulations aimed at promoting non-discrimination, but it isn't the specific title of legislation focusing solely on housing discrimination. The Home Seller Protection Act does not exist as a well-defined law in the context of fair housing rights and protections; it's likely confused with the other acts mentioned.
