Based on the Breakeven price for Pine grove condo(next door) failed enbloc years ago, the price wont say cheap, but its reasonable. And like you said, all the condos all lao kok kok, very limited comparison, so once cant definitively say 23xx 24xx is expensive.
Whether its cheap, i'd like to highlight, now the property market is white hot, no developer gonna be charitable and sell you "cheap", the prices are adjusted to move units, and yet make money.
as for your exit price, all depends on the surrounding 2 condos, one on your left(pandan) and one on your right (pinegrove), if some developer suka suka come in an swallow either of those gigantic things at a updated enbloc price, overnight you make money liao.
