I'm not a Financial Advisor so I'm not qualified to make suggestions. But a lot of people find this [0] flow chart useful. It's UK focussed and you can probably skip to Step 8 (so maybe not that helpful?) but what it says for most people is that they should look at making long term investments in low cost index funds in a tax efficient savings wrapper (e.g. an ISA account in the UK)

Buying individual properties as an investment can be a huge headache, even trying to sell the investment can take a long time. And as the other reply said, it is quite risky to have so much tied up in a single property where anything could happen to it.
