Before I build my own, has anyone seen or got a good tool for mortgage calculation based on cost, tax reductions, repayment, initial input, offset by interest on earnings etc.
That sounds way too complicated. Just borrow what the bank will lend buy something for 50% of that and then spend the rest on upgrading your kitchen so everything is wifi-controlled.
Everyone just borrows as much as humanly possible and (should) invest the spare cash any way how. Investments should return 5% + annually, mortgage will cost significantly less than that for the foreseeable future.
