There are also classes out there where they teach fix/flip and coach on your first house (or something similar). Also, there are podcasts here, and books and videos on BRRR that should cover the basics. I would recommend getting the basics of the basics on the process before approaching a mentor, save them for the advanced stuff :)
This being said, you shouldn't have a hard time picking this up if you know how to manage a project/crew.
- find a home that needs repair, preferably off market so you don't compete with retail buyers.
- walk the property with a contractor or specialty contractor(s) (electrician, plumber depending on the issues) to get an estimate(s) of the rehab. Being new to homes, you will want at least 3 estimates to get the number down.
- Buy the home below market value with the appropriate as-is value, presenting your low offer based on x,y,z repairs.
- close, break ground and start rehabbing! Dumpster outside on day 1!
Don't go with anything too old or too broken on your first few flips.
Real life example: A couple not familiar with investing bought an old house on my street to "fix". I got to talking to them (after close), and they had NO idea how much it would cost to fix and were asking me. This cost needs to be factored into your purchase price! Turned out the house was so old and broken, it's a demo and build lot. now they re-sold it at a loss, because they bought it off the MLS at retail price and didn't realize how bad it was.
