Your lender should have explained your options. You can get "gift" money from relatives. There may be some sort of down payment assistance programs available in your area (but this is typically in the form on a 2nd mortgage and not "free money"). If you're interested in a rural area, there's as USDA loan program that requires very little money down. If you're a Vet, you can qualify for a no money down loan through VA loan. Other than that, you have to do it the good old fashioned way -- SAVE!
Buying a home costs money. People are looking for ways to buy a home without having to put anything into it. This is the primary reason for the market collapse. People were getting loans who couldn't afford them.

I'm a huge advocate for home ownership, but I see so many people buying homes who shouldn't be.
