Cash back mortgages have their pros and cons:
pros:
*if you need the cash back then it is nice to have it
*if you take the cash back and put it directly on the mortgage as a lump sum payment you may end up ahead
cons:
*often a lower rate will end up putting you further ahead when you look at the monthly paymnent, interest paid and principal balance at the end of the term
*if you break the mortgage you will need to pay back a pro rated amount of the cash back
*some lenders do not port the cash back portion of the mortgage so if you move within the term you can port the mortgage (rate and term) however may need to pay the cash back at this point
Hope this helps. If you care to discuss more case specific feel free to give me a call.
