The result of the bidding process cannot be predicted. The indicative interest rates shown are estimations from UBS key4 mortgages on the basis of previous loans with the financing parameters shown. Additional parameters may be taken into account when checking your financing inquiry. Please contact UBS key4 mortgages to discuss your concrete inquiry.
