if you decide to purchase the property, you will need to go subprime - Start, GE, Stepstone or Springboard.
On the information provided, no one else will consider you.
Just for reference, 125,000 over 30 years (assuming you're younger than 50) at an average subprime rate of 8.5%, your repayment would be €961 per month. The rate you get could be higher or lower than this.
if that works out to be less than what you are currently paying, then maybe you should consider it.
Be advised that you would be repaying your short term loans over a much longer period and it will work out to be more expensive over the entire course of the mortgage.
Good Luck
