Ready to move vs under construction

Ready to move vs under-construction homes come down to two basic facts: ready flats cost 10% to 30% more with 0% GST after getting their completion papers, while under-construction units are cheaper upfront but carry a flat 5% GST. With a ready home, you can move in right away, check the actual rooms yourself, and stop paying rent alongside home loan EMIs.
On the other hand, buying an under-construction flat means waiting 2 to 5 years for the keys, but you get to pay in small steps as work happens and can see a 20% to 35% jump in value once the building is done. If you need a place to live today without any delay or stress, go for ready-to-move; if you want to grow your money and can afford to wait, an under-construction flat gives you a much better deal.
