In general the best way to invest in real estate is by buying your own home. Additionally you may want to have a second home, like a condo in a city where you often go. This would not only protect your money by the investment in real estate, but also saves you money as you don't need to stay in a hotel.
And last but not least, of course you can also rent your second home out, so you'll just earn money from the rent. It might be even more than your mortgage payment, so your house would be for free in that case!
Of course you can invest in stocks in The Philippines, but did you ever consider investing in other continents like Europe? Check out the financial calendar of The Netherlands for an overview of the shares listed on the Dutch stock exchange.

Of course you may want to look for investment in real estate outside of The Philippines and what country may be more attractive for that as the safe Switzerland.
