1) Borrow the money from a family member or 401K
2) Get a gift from an immediate family member
3) See if your state or county has a grant program which can be used towards the purchase of a home. Some states have grant programs which are either funds or a 2nd mortgage which can be used towards a home purchase.
Other than that, I don't have an answer for you.
