How long after refinancing your home do you have to wait before you can refinance again?

Some lenders require 1 day, some 6 months and some 1 year. Also read your note and make sure you do not have a prepayment penalty. Fanny Mae, Freddy Mac, FHA, VA have there own guidelines if you are going for that type of loan. Private mortgage banks and some banks like US Bank do what they want. They make up there own guidlines.
