With your current achievements, I believe you might want to start to take a look at private property investments as it has seller commitments as compared to public housing. You might want to start small with a 1 bedder from a new launch that has higher capital appreciation, which suits your investment needs. And selling it away 3 years later it helps you to do forced savings and in fact earning the downpayment for your own future housing. I saw this cheapest new launch in 2019, there are tons of info in this developer site, you might want to check it out. Cheers
