That really depends on what type of financing you obtain from a lender. There are many first time home buyer programs around where you will be able to put down anywhere from 3% to zero down depending on your situation. There are also MFA programs that can actually assist you with a down payment and you will be able to own your new home with little out of pocket expense!
