Final answer:
A home can be deemed a person's principal place of residence if they've occupied it for 2 of the past 5 years, which may impact legal benefits or tax requirements.
Step-by-step explanation:
A home can be considered a person's principal place of residence if they have lived in it for 2 of the preceding 5 years. This concept is often relevant in legal and tax contexts, where certain benefits or requirements are tied to the residency status of an individual. For instance, it might affect the eligibility for a homestead exemption on property taxes or the exclusion of capital gains upon the sale of the residence. The specific rules can vary by jurisdiction, so it's important to consult local laws or a professional for advice in a particular situation.
