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.

I'm not going to make an emotional decision because it's my mom.

I would hope we go into business with people we trust, but still we usually outline how things should go in the event of things going south as it is easier to compromise fairly when everyone is levelheaded, rather than after the fact when emotions are on the line.

Go talk to a landlord of a rent controlled or stabilized apartment in New York City.  

Have control over things that are your responsibility.  

Scenario: The sellers are backing out of the deal, but you have considerable amount of time, sometimes money, and investment emotion in a deal and all of a sudden... seller changes their mind?

I make money when deals close - not on all the BS before there is an offer, so I control my activities that could be a waste of time.

It was my former home that I turned into a rental, rather than selling, and I brought in a property manager to keep from being "emotionally attached" to the decision making.
