School me about REITs & Tax Lien Property

[Franky Juwana]

Hi all, 

I'm browsing my options in real estate investing, I came across REITs and Tax Liens. Does anybody have experience in this type of investments and in terms of REITs, I heard there's almost 40% tax on the dividend? and what other advantages and disadvantages on this? what's the average return on REITs? 

For Tax Liens, how can a small investor like me can purchase in NYC, or any other places? do you have any thoughts on advantages and disadvantages on tax liens?  The ad late night really made this looks so easy, but I believe there are more to it. 

thanks all
