@Ent319 That extra 0.5% (the difference between 3.2% and 2.7%) will cost you an extra €10k in interest (approximately) over 5 years. That will almost wipe out the value of the cashback (€12k), especially when you remember that you'll have to pay fees if you want to switch at the end of the 5 years. (The €400k versus €406.5k makes very little difference.)
And you might not even be able to switch again after 5 years – see
here for a list of possible reasons.
Most cashback offers are terrible value over the medium to long term. (I'm not including AIB's and Haven's cashback offers in that, since their interest rates are good.)
If you could help me understand this a bit better I'd appreciate it.
Let's assume flat costs of €1500 to switch mortgage including solicitor fees and valuation. To make a like-for-like comparison this would have to be factored into a switch for both options (I think?) so the €1500 would cancel the other out and can be disregarded.
So to compare the choice would be:
Option A: €400,000 @ 3.2% for five years with an additional 1% cashback on year 5 applied to reduce the mortgage principal
vs.
Option B: €408,000 @ 2.7% for five years,
Assuming a 30 year overall term, and using the amoritisation calculator
here, the remaining balance on
Option A after five years would be €353,000 and
Option B would be €360,700.
€360,700 - €353000 = €7,700 difference in principal
Option A would have paid €60,700 interest and €43100 principal over the five year term. Total payment = €103800
Option B would have paid €52000 interest and €47300 principal over the five year term. Total payment = €99300
€103800 - €99300 = €4,500
€7,700 - €4,500 = €3200
So assuming a switch
had to be made, under the cashback option you'd be approx €3,200 better off – unless I'm mistaken? The math obviously isn't as good if the 2.7% choice was available by staying with an existing provider as there'd be no solicitors fees / evaluation.
That €3,200 is then saving you (€3,200 * average interest rate for remainder of mortgage ^ 25) - €3,200. However, you're stuck with another cashback lender and the switching train would have to begin again after a few years, incurring another €1500 in fees.
Do I understand this right?
