The superblock market supply here is huge, you can imagine what 16 apartment blocks in a Meikarta will do for instance. Now, from an investment perspective there are the (super) rich that buy multiple apartments and who probably don’t lose one second of sleep if they’re empty and the (rather new) middle class who take a first step on the real state ladder.
Don’t forget that for many of these (small) apartments the developers offer a (mandatory) installment plan of 2-5 years.. This has a similar effect as a (short term) mortgage. But the monthly amounts are much higher than with a 20 year plan and those developers don’t do background checks by credit managers as the financial institutions would.
And newbies think after some calculation it should be possible to pay the monthly amount if both partners work. Of course they expect long term rent, as well as an increase in value of the property. But often even before the completion things turn sour.
So there are quite some lucrative buybacks by the developers and good deals to be done since people need the cash fast.
In case of large houses, there is quite a supply but many are turned into commercial or kost since -also in Indonesia- young couples can’t afford and don’t want huge dwellings anymore. They buy 2-3 bedroom 1 bathroom townhouses with a small terrace at the back in projects in the suburbs. So these ‘palaces’ stay much longer on the market in cities as Jakarta, while the youngsters buy in Serpong, Cibubur, Bekasi, Depok, Cikarang etc. to live there and commute. In Jakarta itself, they often only can afford the Hak Pakai projects.
