We've got much less mortgage wiggle room

Hello, I'm working on a piece about declining mortgage ‘wiggle room,’ with banking trade body UK Finance measuring that disposable income after housing costs is being squeezed by rising interest rates, inflation, higher taxes etc.

I'm looking for anyone with a mortgage, be that a recent homemover, a first-time buyer or someone who's remortgaged in the last year or so, who's happy to speak about their changing costs, please. 

This is for case studies happy to be featured in The Times, rather than expert commentary, please.

Thanks!
