By utopian I mean 4% for 20 years fixed interest. Actually, I really like the proposal we received. I am only confused that for the first 13 years you only pay interest and do not repay anything.@emerMy partner and I work in the same profession, for the same employer, and also earn the same. That is why I immediately halved the special repayments, as each of us would contribute equal parts. The 2000 is our self-imposed minimum for special repayments. In reality, it will probably be a bit more.
