The REIT option has certain advantages to consider.
Diversification - your investment is more broadly based so you get less impact of bad tenants, large ticket maintenance etc.
Liquidity - if you need to convert some of your investment, you can sell a portion of your shares, in stead of having to sell an entire property which is expensive and time consuming.
Administration - REIT shares don't involve registration with RTB, LPT, formal notifications to tenants for rent increases, HAP paperwork, phone calls re broken plumbing at 2AM etc.
For large investments, its always worthwhile visiting a wealth management consultant to ensure your investments meet your lifestyle and objectives. Property may not be the best investment for you at all.
