I'm in the lucky position of being able to pay off my mortgage this month.
Building soc have suggested that rather than fully close we leave a £1 in it just in case we want to borrow more in the future.
We have no plans to move and whilst we may extend, we'd seek to fund via savings as the work wouldn't be huge so this seems unlikely
That said, my dm recommended this too so I'm wondering if I'm missing something as I sort of don't see the point?
