Today was the appointment at Interhyp.
According to initial calculations, it is feasible that we keep the house (repayment would be reduced), acquire the land, and build a house.
Most banks do not offer a loan under 50k, so we should take out about 55k for the land. The initial interest rate was about 1.4% with a fixed term of 2 years, the variable interest rate was around 2%. Repayment would be about 21%.
I also recalled that we have already registered a land charge, whose outstanding debt is almost lower by the amount of the new loan than the originally registered land charge.
The question now is whether the current bank would lend us the amount without a new land charge. That might possibly save costs and effort. The advisor wanted to clarify that.
