Which Strategy Is Right for You?
Bi-weekly payments are the easiest to implement — most lenders can set this up automatically, and since it is just splitting your existing payment, you do not need to find extra money in your budget. Monthly extra payments give you flexibility — you can change the amount whenever your financial situation changes. Lump sums work well if you receive irregular income like bonuses, commissions, or tax refunds.
