reit of course haha.

i think u have ask twice, seems like no body can give u an exact answer why not u take a look at this http://mreit.reitdata.com/ (MY reits) or u can have a look at http://reitdata.com/ (SG reits) from there what u can see is the estimated yields and gearings of respective reit ...... try to shorlisted it into few say about 3-4 reits .... then decide at ur own risks .....
but personally i will go for arreit, starreit. former is governments reits coz all its properties was leased back to government agencies or department or companies more secure long term tenure, latter is our YTL subsidiary and the price seems no movements since last year(s) coz still waiting for the properties to be injected to it. Another which is quite secured alaqarreit coz all its buildings were leased by KPJ hospital or KPJ related subsidiary, so i expect this risks is lesser. the price now high or low (or when can enter) is another questions which is quite subjective, u have to decide at ur own risks. now is ur choice 

personnally i will go for stareit coz the capital appreciation is a good bet ....... sorry for being too hardsell .......
