If you'd said that at the start, you'd have saved me a post. This I agree with.meaning your rate not the banks rate, fix in on top of the banks rate.
If I were to take the difference between a repayment mortgage and an IO mortgage and stuff it under a mattress every month, I'd be in for a nasty shock at the end. The 'savings' simply wouldn't repay the mortgage.again why not ever go for a IO mortgage? saving the equivalent of difference between IO and repayment each month should give you plenty of savings for when you need to pay up.
The reason for that is simple. As you repay a mortgage, the interest bearing portion decreases, so you pay more off the balance with the same monthly payment.
Taking the above into account, there are two flaws to your argument:
- You need some form of investment vehicle to make up the gap between the IO and repayment balance. That implies risk. Just ask anyone who got themselves an endowment mortgage in the early 90s - or, more recently, put their savings into an Icelandic bank.
- In the absence of the investment vehicle, an IO mortgage simply works out more expensive.
