A mortgage: the most expensive decision of your life
This is the cheapest loan on the market (RRSO usually 7.6–7.9%) and also the longest (20–30 years is the norm, up to 35 in some products). Half a point of RRSO over 30 years on a 500 000 PLN loan adds up to roughly 60 000 PLN of total cost.
Fixed or variable. Fixed for 5–10 years buys you peace of mind: you know exactly what you pay each month for the fixed window. Variable, tied to WIBOR 3M or (from 2025) to WIRON, looks attractive today, but it recalculates every time the NBP reference rate moves. If you plan to keep the loan to the end, look at fixed even when it costs half a point more.
