To think that it's best to have a longer term mortgage and overpay?

As opposed to a shorter term one and feel suffocated by the payments

Yes agree. We just got a 33 year mortgage, we want to be comfortable and have fun money. We won’t live there that long anyway, will downsize probably in 15 years.

That's my life philosophy... Some financial decisions have to be based on the life I'm living today and future planning cannot happen at the expense of my current quality of life.

That's what I've done and payed my mortgage off in just under 10 years. Of course, I also benefited from very low rates and my penalties for early repayment were miniscule (something to the tune of 0.01%). You will need to check the terms when it comes to overpaying before committing to the lender.
It did mean slightly more of penny pinching for a while but I was not militant about it and some months chose to spend money on other things. Given the recent increase in rates, it was absolutely the right decision at the time.

We paid a 35 years mortgage in 12 years by doing this. 35 was the only really affordable option to us at the time, but after a couple of years we both got promotions and put any extra in to the mortgage
