Sounds like you have nothing to worry about. Your offer has been accepted, and your grandma has agreed to give you any shortfall of funds.
I suggest you get a closing statement from your lender. This will have the amount of funds you will need to pay at closing. You can determine from the statement how much money your grandma will need to give you. Perhaps she would be willing to put the funds in your account now.
Congrats, and Best of Luck to YOu.

Congratulations, and good luck to you on your great investment!
If it is a concern to you, just contact your lender and he can clarify details for you.
Good luck on your closing and congratulations on the big step!
