Rebate on Mortgage Interest Relief

Hi there,
I've recently discovered I haven't been claiming mortgage interest relief on my home. Am married, it's not a first home...but have calculated that we've paid over €61,000 over the past five years in interest.
Any idea what sort of a rebate might be due?

You can claim back as far as 2004 now as far as I remember. You will need the TRS1 form [broken link removed] to set it up and a seperate TRSP form [broken link removed] for each year you wish to claim back.

How long since you first bought a house also?

Thanks PaddyW,
Bought in 2004 and have done all that - got interest statements for each year and have sent of my TRSIp form....but was just wondering how much I could expect - don't want to over-estimate the figure and be disappointed!
