Getting A Bonanza: Pay Off Debt Now Or Over Time?

Getting A Bonanza: Pay Off Debt Now Or Over Time?

I am going to be coming in to a large amount of money and I should be able to pay off some of my mounting credit card bills, over $15K. Should I pay it off all at once or space out the payments over 3 or 6 months? I would like to buy a house in a year and want to get the biggest gold star on my credit report I can.
