Is a 20% down payment always necessary before buying a home?
TL;DR: No — many lenders approve lower down payments, but a smaller down payment usually means a larger EMI, more total interest, and sometimes additional insurance costs. Whether that trade-off is worth it depends on what the extra years of waiting to save 20% actually cost you in rent and opportunity cost.
What a 20% down payment actually buys you
A lower EMI, less total interest paid over the loan, and in some markets, avoiding extra mortgage insurance required below certain down payment thresholds.
What waiting to save it costs you
Continued rent payments, potential property price appreciation you miss out on, and the opportunity cost of the additional years — all real costs that a simple "always save 20%" rule ignores.

Frequently asked questions
Does a smaller down payment always mean a worse deal?
Not necessarily — if property prices are rising faster than you can save, waiting to hit 20% can cost more in missed appreciation than the extra interest from a smaller down payment. It genuinely depends on your specific market.
What down payment do most lenders actually require?
This varies significantly by country, lender, and loan type — check your specific lender's minimum rather than assuming 20% is a universal requirement.
