Becoming a real estate is a great way to learn the culture of that side of real estate - what you won't learn at Realtor School is how to invest - creative financing and making money.What you will learn is how to keep from getting sued - how to use their forms and making full disclosures.Learn the business from their prospective - but keep in mind (before you become brained washed) that your real goal is to become a successful investor.So - follow their rules - but start to study real estate investing - get a mentor - go to auctions, tax sales - foreclosures - make offers on expired listings.So to make your broker happy -- list a few properties and sell some also.Apply for a credit line, check protection and set up some joint ventures with friends and relatives.You WON'T make that much as an agent - but you'll become wealthy if you learn how to CONTROL and ROLL real estate - make sure you learn advanced creative real estate formulas and use those principals often.Good luck with your release from incarceration of employment.
