Tradeoffs
Reducing-balance method; flat-rate quotes look cheaper but cost the same. Prepaying in early years saves disproportionate interest (₹5L early-year prepay can save ₹15L+ in interest vs late-year). Tax deductions (Section 24/80EEA for home loans) reduce effective rate by 25-35% in 30% slab old regime.
