You are most-likely looking for trouble if you think you can find a mentor, or someone to shadow. Many people look like they are successful, but don't know one bit more that you with the exception they know what they can't do. I call what you are looking for, "The Blind Leading The Blind".
As stated in my most recent post, after reading and writing on BP and trying to help investors I am getting frustrated due to the crazy questions and insane advice. Investing is real estate is not difficult and anyone with a 5th grade education, or less should be able to invest with no personal help from others, but I definitely see where a high percent of people who want to invest treat the business like it is a hobby and not a business.
Don't listen to a people who claim they are successful and don't watch a few videos and don't read a few books and don't believe that nobody loses money and don't believe that so-called successful people are successful and don't believe they can walk on water. I've been investing in real estate 55+ years and still have the exact same fears you have every time I purchase a property, but the difference between myself and other investors is I don't treat the business like a hobby, I analyze a property 50 times (so-to-speak) before I make a purchase, I don't cross my fingers, don't pray to god for success, never make a decision based on another person's advice and I am 100% positive about the outcome before putting a property in escrow. YOU CAN NEVER EXPECT SOMEONE TO DO ALL THAT FOR YOU and everyone has their own agenda that usually does not align with your agenda.
The most important factor about investing in real estate is analyzing the property, doing the math and the ability to do realistic projections. Very few investors have those abilities and almost every investor lacks in doing the math. If you every think you have a mentor who can teach you the ropes in regards to analysis then you are most-likely 99.89% wrong because I deal with even professional and experienced brokers and they are almost always lacking and wrong.
Now the positive things to write about. Read a book called 'The Encyclopedia of Commercial Real Estate Advice' by Terry Painter. You can get it on Kindle or paper for $29 and it is the best book I ever read. Put it on Kindle so you can read it a little at a time wherever you are like when waiting at a doctor's office, at a coffee shop, or wherever. Don't focus on only the positive things because of the gold at the end of the rainbow. Pay special attention to what does not work. Read the book several times.
Wholesaling is much difficult and you could possible make a few dollars, but you won't get rich and I would never waste my time with it. Flipping is super difficult and very risky. I never met a person who made good money flipping and even the pros lose a lot of money on a percent of their flips. The big money is in multi-units with 4+ units. You will never understand how much you can earn when you ask the wrong people and when you don't focus on learning the math.
With no big head, I feel like I am one of the best real estate analysts you will ever meet because I don't charge money and I will do the math, extensively, turn over every rock and look under every leaf, for free, only for investors who don't treat the business like a hobby and for investors who don't want to be a shadow, but do want to work hard enough to really learn, understand the business and actually want to make their own smart and final decisions.
