I'm considering purchasing a property that we would need to extend ASAP.
I'm not sure how much mortgage we should apply for. We have up to 50 LTV but we would rather not wait to extend.
If for example we put down 40% deposit to benefit from better interest rates, would we be able to borrow more during fixed term if that meant out LTV increased to 70%, or would our rate increase for the existing borrowing?
Or would it be better to apply for 70% LTV in the first place?
