I love REIT as an investment. They are easy to understand (it's some properties and debt attached to it), provide regular income and offer real-estate exposure with diversification, simplicity, liquidity and often higher yields than direct property ownership.
I have long maintained a spreadsheet of the Singapore REITs for my own usage, compiling hundreds of financial reports over the years. But I realized that all this work could benefit others too. I wrote REIT Oracle to present this compilation of data.
The site content now is rather bare but I feel it's already more complete than most other sources out there, and you can use the screener to find the most profitable (or most discounted, or least leveraged...) REIT. Much more stuff will be brought online in the coming weeks as I have a lot of data to use and plenty of ideas, stay tuned!
