Final answer:
Bob and Charlotte must be at the age of majority, which is typically 18, to purchase a home. Marriage and family composition, such as being a same-sex couple or having children, do not affect this eligibility.
Step-by-step explanation:
Bob and Charlotte can purchase their first home once they reach the age of majority, which is 18 in most jurisdictions. At 17, they are still considered minors in the eyes of the law, and therefore may not be able to sign legally binding contracts such as a mortgage agreement.
However, it's important to note that rules can vary depending on the jurisdiction, and certain circumstances, such as emancipation or if they are considered legally capable for specific reasons, could allow them earlier access to homeownership.
Eligibility to purchase real estate is typically not influenced by marital status, sexual orientation, or family composition, meaning that whether they are a traditional or same-sex couple, or have a child, does not directly impact their ability to buy a home, so long as they meet other legal requirements like being of the age of majority and having the financial means.
