Is there a good place online to see ratings/rankings of REIT's? - reit ratings

I think investing in REITs. I'm not sure whether they are classified as mutual funds, stocks, or ETF. So I am about how they like stocks or mutual funds display confused. Is there a free site where I can do research on them. Any information would be useful.
