Final answer:
Common covenants found in a mortgage include restrictions on the use of the property and aesthetic requirements, but not a prohibition on selling the house to specific ethnicities or religious groups.
Step-by-step explanation:
Common covenants found in a mortgage include restrictions on the use of the property, such as limitations on building structures or fences, and aesthetic requirements to maintain the neighborhood's appearance. However, one covenant that is not typically found in a mortgage is a prohibition on the sale of the house to specific ethnicities or religious groups. This type of discriminatory covenant was more common in the past but has been deemed unconstitutional by the U.S. Supreme Court.
