All the information above is what you need! You asked about credit and yes, it's possible to begin your real estate journey without good or great credit. I'm not sure where you are, but I spent time this week talking with lenders. 620 and above should be able to get you conventional financing with the lenders I spoke with and 640 and above for FHA financing. Outside of going a "traditional" route, I've read on private lending, owner/seller financing, and a heap of other ways to get funds for your projects.
Just as @Brooks Rembert mentioned, use the search tool in the upper right and literally type in financing with good credit or poor credit. I've found an answer to pretty much everything I need!
You certainly need to invest your time and resources in repairing your credit. I've gotten mine above 750 now so it's very possible with discipline and determination, all the ingredients you'll need to be a real estate investor anyway! Good luck!
