Need help with "New Laws that affect RE Investors"

[William R.]

I have to write a paper listing various new laws that affect Real Estate Investing for example The Law passed that requires one to have a License to be able to discuss Financing, which has the effect of making note creation without a mortgage licensee illegal

Can anyone help me out with a few topics of various laws since the recession that have hampered or changed how RE Investing is done? I would be most grateful and write you in as a source :)
