It depends what this 10m represents of your total profile. If this represents over 80% of your net worth, I'd advise against HK property. Property exposure isn't inherently bad, but being so "all-in" is ill advised. If this is all you have, I'd advise some amount of property exposure through some sort of exchange traded REIT, maybe Link REIT, but I'm personally pretty bearish on HK property. The remaining proportion I would go for an Equity / Fixed Income split depending on your stage of life.
Now. It's a little bad for all those asset classes. Valuations are high for equities, interest rates are rising hurting fixed income, one might be tempted to wait out a correction before going in, but I kind of live by "time in the market beats timing the market"; if you invested in the SP500 October of 2007, the peak pre great financial crisis, and held it to today, you would still be up almost 100%.
I think there was a study saying 2/3rds of the time, investing all of it at once is the correct thing to do vs maybe 25% every quarter. That being said, this is psychologically a lot harder to do.
You'll be seeing daily P/L's much higher than you're used to seeing and that could tempt you to do some impulsive trading.
