That should be all that is required, but I am in Florida and it appears you are in Virginia again there can always be a difference between the states and what is required.
Best wishes in your home purchase.
I have had cash offers as a listing agent and asked for the buyers bank statement and received it. It will be necessary for you to provide documentation to the seller showing that you do have the funds to close. Either a bank statement with all of your personal information redacted or an official letter from the bank saying you have at least the amount of the sale. This way the seller knows you are serious and capable of the purchase. It really does make sense when you think of it. I would be equivalent to a pre-approval letter if you were getting a loan. Good success with your purchase.

Most (if not all) sellers will request/require proof of funds - to show you actually have the cash for your offer. 'Black out' your account numbers on your statements before you give them to your Realtor so no one (including your Realtor) has your account numbers.
