Great Credit Score But No Money Down?

Hi everyone, i'm looking to purchase my own home within the year. It will be my first home. My credit score is 747. I am 34 yrs old...single, i have no children and i have no credit card bills.I do have a car and my payments are $289/month. Those payments will be over a year from now. I have $3000 saved in my bank account but i'd like to use that towards moving, hiring an inspection officer and so on. I'd really like to buy my own house soon....looking into the Delaware area. Can i still purchase a home with no money down in this day and age? Also is it true that having at least some money down lowers ur interest rate and also would a conventional or FHA loan be my best option since i have no money down? Thanks for all replies
