Noida Extension: struggling to balance tax benefits with market timing

Noida Extension (Greater Noida West) — been seeing some interesting shifts here lately. I work in real estate, but buying for myself is different. With Jewar Airport and FNG Expressway progressing, prices are up. I'm balancing tax benefits (Section 24, 80C) against market timing. Should one hold for maximum long-term gain, or is the current market ripe for selling? What overlooked tax strategies do you utilize?
