I'm definitely part of it.
Single mother of 2, professional job, income of around 46k, which you'd think was decent. Public sector, so no real pay rises for the last 12 or so years. Managerial role with nowhere to go next; I've hit the ceiling of what is possible.
When the mortgage increase kicks in I'll have nothing left to give. Already driving an 18y.o. car, bought an ex council house a year ago in a rough area to escape the spiralling cost and insecurity of renting (17 house moves since the end of my uni days 20 years ago, mainly due to a succession of shitty landlords), food shops are more and more a case of disappointed kids when they can't get what they want due to cost, house, in winter, is already on 18C max.
I do everything myself already - most repairs, all gardening, cooking, cleaning.
We rarely have days out and when we do it's walks, park, swimming, all local. Had to tell the kids no holiday away again because I cannot justify the £300 on 3 nights away.
I save what I can now, before my fixed deal ends, but so much of it lately has been eaten up by urgent repairs needed on the house. Yet I'm glad I bought, because houses like mine have gone up 20k in the one year I've lived here.
