if u have a lot of money to throw away and want to use it for your own stay then not much to worry about. Since it is already completed worse come to worse just use it for your own stay, and maybe if anyone of us come to Jakarta u can rent it out to us at a good price lol Jakarta is my grandparent's hometown but I've yet to visit. Heard many good things from friends as far as holiday is concerned. Do you like your stay there?

However as an investment it is risky for all the reasons you posted. Also at this economic climate, who do you think will rent the condo?
