I'm going to sound harsh here, but whatever.
I've lived through this part of the cycle at least three times now. It sucks, but home ownership is always a gamble, the value of your investment may go down as well as up etc etc.
Do people not understand that? Do people really think they can opt out of the risk? Do they think they can put themselves in a position where a move in the rate to something that is well within a historic norm means they can't pay the mortgage?
While I appeeciate the numbers have changed with the invcreased cost of housing, the principles remain the same. When I bought my first house I could have got something bigger and better, but did not because of the risks, I could have paid less per month but did not and took a more expensive fixed rate because of the risk, I've paid a specific insurance to cover many circumstances of being unable to pay because of the risk, when I was in a position to move I did the same things again because of the risk. I've paid for my risk management, both financially and by the propert I have been in.
People that haven't done should now be bailed by the ones that have? We seem to have a significant number of this generation that think they are owed and can be reckless without consequence. No. You can push the boundaries of what you commit to, but that is your risk.
It may surprise you to know that I don't disagree with many of your points (but not all). I too was in a situation not long ago where I could have got a large mortgage, cheap and chips interest on it, to buy a rather large house that I could easily afford at the time.
But I resisted for the same reason as you stated. I didn't trust that interest rates would not reach a good 7-8%. So I didn't. I kept my tiny mortgage on my humble home and battened down the hatches and I'm glad I did. Even if interest rate double what they are now, I'll still be OK.
But imagine you are young, on less than £30 - £40k per year, have been told (rightly) that you should own a home rather than pay someone else's mortgage for them and you did just that. You went to see a mortgage advisor, they wanted your money so they told you what they thought you wanted to hear. The government chipped in with some cash as well that you have to pay them back (which further increases house prices at taxpayers expense) and you thought you did everything that the government, your mates, your mortgage advisor, Martin Lewis and just about every Tom, Dick and Harry told you to. You did this, not because you didn't read the threatening small print, but because the alternative was the fact that you would be stuck in rented accommodation forever with no chance of getting out either way, no matter happened with interest rates.
What options were there for younger folk only a few years ago? Sleep on the top bunk above your brother/sister's bed in your parents 2 up 2 down until you turn grey? Get yourself or someone else pregnant, live on a sink estate and raise your kids next to drug dealers and burnt out cars? Spend a fortune on rent paying someone else's mortgage alongside your student loan, trapped forever until a relative potentially dies and leaves you something? Take the risk and buy a property that seemed like a steal at the time and prey that interest rates don't rise too soon?
Yeah, there are risks and you sign many documents saying that you accept them. But what are the alternatives?
You know as well as I do that they'll end up being baled out by the taxpayer sooner or later. Whether they end up getting locked up in prisons, warehoused in temporary accommodation, on Universal Credit, move abroad and thus contributing to the UK's terrible skills shortage and lack of productivity, or through rent/mortgage top-ups.
None of those options sound good to me. I thought we learnt over a century ago that access to healthcare, housing, education, food, warmth, clean water, safety, freedom, democracy, labour in exchange for fair wages and opportunity to progress in life were essential to living in a civilised country?
If you obide by the rule of law, work hard and pay your taxes, you should be able to access all of those things. Some people who can't will just simply turn to other means of achieving those goals. My hope is that is it's the ballot box they turn to. But if you reach 30, can't move out, can't buy a house, can't have a family and can't get on in life when what should you do?
It ain't like when we moved out, bought houses and had kids. That country just doesn't exist any more. Me and you will be fine, but our children won't.
