Should I put 20% down or as littke as they would accept

[Gilbert Lugo]

Finally getting my hands dirty and getting into the game! I've been qualified for a good loan with very good APR under an FHA and according to the lenders variables I can own the property with very little down. But I'm a bit unsure if I should put the 20% down how I planned or If i should put as little as they would accept and pocket the rest of my cash? Any ideas or suggestions will help. Thanks !!
