Yeah I think once you drop under 60% there's probably very little difference.
When took out mortgage in 2020 it was 90pc.
Then it was 75 (I think) in 2022.
But getting to 70 (do I put more cash into it) either side wasn't worth it.
I do remember it making a difference being 75 and not 80 (ie if house was valued down)
House was valued down but still under the threshold.
