I own individual REITs and recently came across the Syfe REIT ETF which consists of some REITs that I do not have. Should I put funds into the ETF or buy the individual REITs?

Syfe isnt an ETF. They use your funds and invest in the REITs individually. It’s no different from buying the individual reits from brokers which might incur more fees. IMO being able to DCA and having a roboadvisor investing in it directly with a low fee is worth if you don’t have much time to manage portfolio.
