Half fixed / Half tracker

Someone asked me the following question today but i was stumped.

"If you are already on a tracker can you change to half on the tracker and half at a fixed rate".

Ive never heard of such a product, but id imagine the banks would go for it. At least the have a person on only half a tracker.

It also gives the person the option of making overpayments on the variable side if they want.

Is there any such product?

AIB told me the other week that you can fix any portion of the mortgage and leave the rest on variable - seemed pretty standard. No trackers though as far as I'm aware.

AIB also advised me that I could not fix half my mortgage and keep my current .75% tracker for the other half.
I would have to move completely to half fixed, half SVR.

Than ks for the info.
What kind of rates were they offering for fixing?

It'll be on their website - from recollection, 2-year fixed is about 2.85%. 1 year fixed is slightly higher.

10 year fixed is 4.25% but have been advised they will change April 16th...
