trading up

I am currently in the process of trading up
I have a house to sell which is worth about 190K
I have a mortgage of about 80k on this.

the new house cost 270

I have about 40K in cash.

Question
is it better to borrow less i.e. pump the 40K into the house.

I am currently with Permanent TSB are they the most competitive?

Does anyone know of a reasonably priced solicitor to go through?
