So I just made a overpayment on my mortgage...

After taking a mortgage on a few months ago I have been trying to make overpayments but its tough, for one there is so many expenses to deal with in a new flat, but also right now it seems like keeping it in cash earning similar interest might be beneficial?

The mortgage is 2.59% APR interest over ten years fixed.

I can get 2.5% interest on a regular saver account up to £300 a month.

Technically I'm better of with the overpayment as of now. But I have a feeling it wont be long and savings accounts will offer quite a bit more than 2.5%

If nothing else its nice to see the Mortgage go down some, I know its costing me about £8.90 per day in interest alone and without overpayments it will be some time before the principle sum starts reducing in any meaningful way.

Holding the rest as cash for now, I have a 5 month bills emergency fund and the way things are going it could well be needed...
