Regarding what Mia earns, she has a limited company so her accounts are public on companies house for all to see. Her 2022 accounts are the latest on there (being for the period April 2021 through to April 2022) and put it this way; it’s not enough to live on for 6 months! Obviously it doesn’t tell you exact wages but it tells you the capital held by the company, which at April 2022 wasn’t a lot. Her 2023 accounts are due in April so it will be interesting to see what the difference is, I imagine she’s made a lot of money this year so the accounts will look very healthy. If she got a mortgage offer accepted then her wage must have been good - I work in conveyancing and for self employed it’s difficult to get a mortgage accepted so she must be doing alright now!
