Which Robo-Advisor has the best REITs portfolio?

You could make things simple and autoinvest (f.ex. only 4 x per year)

into Lion-Phillip S-REIT ETF

Building onto what Davin said,
Most who invested suggested to DIY Reits.
Why?
1. There are about 24 s-Reits (forget the number)
Learn how to find a good Reits could potentially earn you more than the Reits index.

2. Costs
   Stashaway Reits is built upon or similar to lion Philips income Reits etf. So u are paying a platform fee and etf fee.
   Vs
   Syfe is building its own Reits portfolio so u r paying platform fee
   Vs
   You buy a good reit. You are paying only the transfer fee of 0. 1 %(from $10)

Your compounded returns will be lesser due to the compounded costs.

So between the 2 robo, I would recommend syfe. If between robo vs diy reit, I will suggest diy

Note that the analysis is according to costs alone. Not the projected returns
