Tim,
I had a look at the Quarterback Loan and have a couple of questions.
When you get the APR offer is that APR frozen for the period of the loan?
In your example of borrowing £30K (assume that is on 6.1% APR fixed over term of loan?) over 15 years I make it £259.09 per month. At 5.1% APR I make it 242.48 per month. A saving of £16.61 per month. Over the term of the loan that makes £2,989.80. Your example says you would receive £5,023 after ten years. This would make it £27.90 diff per month and there for effective charge of £231.18 per month and effective rate of 4.4% APR.
The reason behind this is that I am trying to decide if it would be worth taking out a secured loan with these people ( assuming I could get a decent rate ) and then pay off a chunk of my mortgage hedging my bets that the effective rate of the loan would be less then the rate that I will be able to get for a fixed rate mortgage next June when my current fixed rate ends.
Do you think my mortgage idea is possible or would it be too difficult to obtain a 6.1% APR?
