These are professionals with additional training and a stricter code of ethics.

Cons: the people are lazy and have zero work ethic causing them to take less pride in the houses.

Five years into the marriage they are growing distant due to the man not sharing her work ethic, ambition or whatever the reasons may be and after a couple of years of failed marriage counseling, she finds out he has been cheating.

You are violating your code of ethics, and sometimes those offers do get taken...

It will be a weeks, months, or even years until you get your first deal depending on your work ethic.

I now have the work ethic and I did not have in my twenties that came with experience. 

Same with a good realtor and the 3%.The 40 hours of training to become a realtor basically just covers legal and ethical, not how to be a good realtor.

There are some advantages however; with a legit hard money lender or Trust Deed investment company, the loan will be researched to meet some minimum investment standard (depends on the expertise and ethics of the hard money lender) and you may be able to get into a quality and size of loan you would not with just your investment amount.

I am just wondering what the real estate agent can legally and ethically do?  

I look for veterans because I know they have a good work ethic and I can train them if they want to work.
