@anotherklutz It's time to chill out.
Ease off getting information from low quality sources like social media, tabloid papers and clickbait internet articles. It's easy to worry yourself sick if you are feeding your brain with bilge. Sensationalist stories get lots of clicks and shares.
It's best to chill out and not pay too much attention to the hyperbolic nonsense. If you want news get it from a quality source that is relatively neutral and doesn't try to whip people up to get clicks. Like The Financial Times or the Times.
Interest rates are not going up to 16% any time soon. There are a whole number of reasons why this is different to the 1980s.
By the way - what think happened to the wealth of people who owned houses in the 1980s and lived through 16% interest rates? Many of them are property millionaires. The baby boomers are the wealthiest generation in human history. People who bought in the 70s/80s typically made more wealth from owning a house than they did for working their job. If we are moving into an era of high interest rates that also means high inflation which means house price rises that would bring your LTV right down. Maybe not in the short term, but certainly over the long term.
High inflation also means high pay rises: people were getting 10%+ pay rises each year in the 80s. Don't assume your salary will remain static.
