House and down payment?!?

The house we are trying to buy comes with land and it's a manufactured home..it appraised for 70,000 and the asking price is 65,000..we've been trying to find somewhere that will let us put 10 percent down...bc every where we have went wants 20% plus closing cost which is too much.does anywhere no where I can find a place that allows 10% down instead of 20% maybe like a website or something and if it helps the house is in Texas..thanks so much<3
