The 'snowball' effect with aggressive installment overpayment

Mortgage overpayment is financial magic. Every additional zloty thrown into the bank reduces the principal itself, which automatically lowers the interest in the following month. The more you overpay, the fewer costs the debt generates – this is the snowball effect. Where to get the funds in a tight budget? Simple: by bypassing agents when buying an apartment, you protect tens of thousands of zlotys in commissions. You can throw this saved wealth into the loan on day one, sparking an avalanche of savings.
