Can mortgage company charge late fees if payment is received by grace period?

A mortgage company usually has a set date that mortgages are due, i.e. the first of the month. Anytime payment is not received by the first it is considered late. However, most MC's have a grace period of 15 days; if it's not received in this time frame a late charge is assessed. If you mail the check on the 6th and it doesn't get to the company until the 17th you will be charged a late fee. The mortgage company must receive the payment before the grace period expires.

So in essence NO they can't charge you if they receive the payment by closing time of the last day of the grace period.

They CAN charge you if you make the payment after business hours, because it is not considered received until the next day, there is no one to process your payment if the business is closed.
