I don’t necessarily recommend anything I’m describing below.
You can, via REITs and REIT index funds. The U.S. financial markets offer REIT index funds with US$1 minimum to open and US$1 increments. (Via Schwab, for example.)
Real estate near the Chernobyl nuclear power station is worthless. Every individual piece of real property is only one industrial incident, asset forfeiture, revolution, invasion, epidemic, fire, flood, or other calamity away from a total writedown — and it’s a fairly long list.
The value of total global investable stocks (e.g. IWDA, VWRD) cannot fall to zero unless human civilization comes to an end. (Which I cannot totally rule out. Giant space rocks exist.)
This is true of real estate in Singapore, certainly. The government is massively interventionist and will strictly limit your upside.
Globally, over long stretches of history, that’s probably true. There are local or regional, shorter term exceptions. Singapore between World War II and the Asian Financial Crisis was probably one such exception.
Cheaper leverage historically, but brokers and financial markets are challenging that. The U.S. margin interest rates that IB charges are basically identical to U.S. adjustable mortgage interest rates, especially when factoring in mortgage costs. Moreover, the options and futures markets let you make highly amplified bets if that’s your thing.
What makes them unattractive in Singapore are the taxes. Real estate is comparatively heavily taxed in Singapore.
