Have you opted to take a lower mortgage than offered?

Maybe it was not the most conventional thing to do but we opted to take a ~192k mortgage when we were offered ~450k. Our reasons were the following.

- We didn’t need a home worth 450k or above

- We wanted to contribute 20% of net pay to S&S ISA so that all our wealth wasn’t locked into our home.

- We wanted an affordable payment even if one of us lose their job.

Have anyone else opted to take a mortgage much lower than what was offered? If so what were your reasons?
