actually that's what i like about equities (blue chips) and index funds. There is diversification across various sectors, and there is ease of entry/exit. Properties can be a money sucking pit for years to come, eg landed properties require regular upkeep (roofing, gardening, pest extermination, water seepage, problems with retaining walls... every big and small thing also out of own pocket); condos have the monthly maintenance; not to mention the yearly property taxes and even more taxes on rental income; and the hefty stamp duties upon purchase and another hefty agent fees upon sale and rental. Sometimes after accounting for all these, the capital gain (if any) is really paltry.
AUD and NZD deposits are good... too bad i missed the boat when both currencies tanked against SGD earlier this year.
