So some options to use other people's money are:
Hard Money lenders - They lend out money based on the strength of a deal. They charge high interest & points for a short term loan. If you have an amazing deal, you could maybe fix up the house and refinance to a conventional loan. Most hard money lenders do not loan to owner occupied though. If the person who borrowed money occupied the house and choose not to pay them lender back, it would be a legal headache for the lender to gt the property. Using an FHA means this method would not be the way to go.
Private Money - These are people that are willing to lend you money based upon whatever agreement you can both agree on. Professional private money lenders don't lend on owner occupied properties. Same reason as above. Other private money lenders can come from your circle of influence, such as friends and family. You might be able to arrange something with a friend or family member. Especially if they want to get into real estate.
Commercial Investing - It is possible to structure a commercial deal so that you actually get paid to do that deal. It's not easy and takes a lot of time to find and put one together. If this interests you, check out some books on commercial investing.
If you can buy a property as buy and hold, you should have enough money to either put down on the property or pay monthly cost on hard money/private money loan until a refinance. If not, don't buy the property. Same with flipping property except make sure you can sell property before the loan is due and you make enough to pay back lenders.
Best advice I can give you is join a local real estate investor association (REIA). Go to the meeting, listen to the workshops, network with people, and buy some people lunch/dinner/coffee to pick their brain. The people in those meetings have valuable experience that can help you get started. Also, you'll find people that may want to partner up with you.
I hope that helps
