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.
If your mortgage loan adjusts periodically, check for changes to the grace period. Some banks make changes with the new interest rate. If your mortgage is sold or traded to a new lender, also note any changes to your official grace period. A credit grace period gives you a few days between the official due date and the time the creditor charges you a late fee. The only people aware of the exact due date and your grace period are you and your lender.
