If you are fortunate enough to be one of those rare individuals who are making a cash offer to purchase a home, it would make good sense to provide some form of documentation along with your offer that shows you readily have the funds available to you for the purchase otherwise the seller may not take your offer seriously. A current bank statement is usually sufficient but other documentation may need to be provided. If you have to liquidate stocks, bonds or some other type of assets first, then your offer should give a timetable on when you will be able to provide proof you have successfully converted those assets to cash so that the sale may proceed.
