Canberra is not that undeveloped. Have you even been there?
They have basic amenities which is enough considering about 50+% of the HDB flats there aren't even ready.
Also, if you wait till it's developed, the price will shoot up so yes, it's like investing in stocks.
The residents knew what they were getting into when they BTO'd there and in about 2-5 years, it won't be a ghost town anymore so what's the problem?
You think AMK, Bishan, TPY all what? Everything created in a workshop, then they throw it into the piece of land? You think the early residents didn't have to wait for their amenities to be developed when towns in AMK/Bishan/TPY were first built?
So yes, you all are short sighted as ****.
If you all rich, you wouldn't even bother with HDBs lah
