Andy Griffith has been married three times. With his first wife, Barbara, he adopted a son, Andrew Samuel Griffith Jr. (born in 1957 and known as Sam Griffith) and a daughter, Dixie Nan. Sam died in 1996 after years of alcoholism.
It is perfectly legal for a rental property owner to require the rent payment in full on or before the first of the month and to not offer any sort of grace period. Even with a grace period, the rental property owner legally has the right to serve notices regarding nonpayment of rent. I have seen many examples of landlords tightening their policies and rules, including a reduction or elimination of grace periods.
Other loans, such as the Federal Direct PLUS loan, have no grace period. If you are a recipient of such a loan, you must begin paying it back on the day that the last part of the loan is disbursed to you. However, it may be in your interests to start making payments on your loan even during the grace period.
