LTV Loan to Value ( e.g. loan of €100k on a house worth €200k is 50% LTV)
PDH Principal Dwelling Home (as distinct from an investment property)
It seems from that table, that the LTV does not matter. You are being quoted 4.5% whether the loan is 50% of the value of the property or 100% of the value of the property.
Bank of Ireland charges new customers 4.1% for loans of less than 50% Loan to Value.
My second question - am I mad to consider fixing for 10 years? - It's an extra €100 per month ==> €1,200 a year ==> €12,000 over the 10 years. The payment would work out at roughly 40% of my take home pay (per fortnight).
You should look at switching to KBC or AIB whose rates are much lower.
I don't think you should fix. It's being discussed in many other threads. Variable rate mortgages are way too high in Ireland and should come down from their current rates.
