Just move away from London. We moved to Manchester 8 years ago as couldn’t afford anything in London with a combined salary of £120k. We initially took a hit to salaries moving to Manchester but regained that now and we have a lovely 4 bed house (250m2) for £350k.
Covid has very much proven that living in or around London is no longer desirable unless you already live there in a house with garden (flats in London are suffering from an extreme lack of sales) and there are huge job centres on the north and midlands.
The problem is Covid has pushed prices outside of London even higher as well as people with high paying jobs and their companies are realising there is live outside of London and remote workers save not he cost of office space.
Our house in Cheshire bought in Sep 2020 has gone up £100k already in just over a year. Interest in that same year on the mortgage about £5500. £95,000 profit. Sure our house is around £1m so if you divide by 4 or 5 to get something closer to the average house, someone would need to be banking £15k-£25k a year just to keep up with house prices. Add in living expenses, renting overhead and saving up for the deposit as well and it shows how difficult it is even for 'middle earners' even with no kids and limited expenses. Never mind people on living or minimum wages etc, they are screwed. Even me being a capitalist tory scum sees this as just not right or sustainable.
There is literally a tax on being poor for housing and then everything else as well.
