Funding advice

[Ace Saxon]

I am looking at a few properties to be my first buy, fix, and hold property. I am needing some help figuring out the funding part. I have a down payment and good credit and my plan is to buy, fix, then refi for a 30yr. My questions are what would be the best source to get in the house for no more than 10% down and what options let me close the fastest? I hope this all makes sense, thanks in advance.
