The best thing to do would be to go to local real estate meetups and meet as many people as you can. You can be very upfront that you are a noobie learning the business but are studying and willing to put in the leg work.
All deals need three things. Money, time (hustle), or knowledge. You only need one to be able to contribute. If you come from a place of seeing how you can find more experienced people deals, they will have a hard time not working with you. Everybody wants deals, and the smart investors will help other people find them deals.
Also, this is what I did back in the day: Call a bunch of those ads that say "We Buy Houses" and they will either be a wholesaler or an actual investor buyer. Say you're new and just wanted to see how you can help their business.
I wouldn't explicitly say you are looking for a mentor because that's kind of like asking random people if you want to get married, lol. Just focus on being of service and helping find deals and that should get things started just fine.
I found a great investor early and I helped him analyze deals, take phone calls, and eventually meet sellers in person. This really gave me the skills early to be able to help investors now as a real estate broker and will be really great experience for your own investing.
Cheers and good luck!
