Thanks for your comments guys,

I guess I have had it ingrained in me for so long that debt is bad and needs to be paid down asap so its hard to reverse that trend.

Richard, what did you mean by this:

If you were a client of mine i would be strongly suggest to you that you looked at IO with an offset account on 1 loan and then had the others as basic rate interest only loans.

Why wouldn't I have a single offset account linked to all of them?

Jamie to answer your question, within the next 10 years i do see myself purchasing a PPOR, however the plan is to go for another 6 – 7 years without making a purchase.
