Question on different funding/loans for real estate flip

[Kaden Dayton]

Hey Everyone! 

This might be a dumb question but what is the difference between a hard money loan and a personal loan you could receive from a bank or a site like credible? Because I haven't really heard of using a personal loan as an option before when reading up on ways to build capital to invest! So I was just wondering if there was something I was missing, or if a hard money loan is very similar to a personal loan and that's why I've never heard it referenced? 

Thanks so much for whatever info y'all got!
