What was your biggest financial mistake?

Was watching an interesting video on YouTube of people talking about their biggest financial mistake and thought I'd be nosy and ask 😁

Mine (aside from having kids 😂) was either:

Taking a credit card out ",for emergencies". It's just amazing what I justified to myself as an emergency when I had that card!

And also taking out a student bank account with a £1.5k overdraft and thinking it was basically free money. Cue the next 4 years of constantly living in my overdraft, my wage not even half clearing it before I spent it to the limit again before the next payday. Sometimes I wish I could go back and give my idiot self a bloody shake.

Being born in 1961 and now having to wait till I am 67 to get my state pension, had I been born before 1959 I would have received my state pension at 60. Second is not putting more money in a pension, instead of companies trying to sell you a pension, it would have been better to have paid someone to help advise me. The third is not knowing I could have paid off my endowment mortgage early, again nobody said we could do this and when I enquired about it, was put off doing so.

You wouldn't. I was born in 53 and had to wait until I was 63 and bit for mine.

@LeTourEiFFEL how did you get started learning more about investing? Books? Financial advisor? It's on my long-term plan (after I've paid off my debt!) but I genuinely wouldn't even know where to start researching.

Google rebel finance school.

Not claiming back higher rate tax relief on pension contributions for years.
Not making extra contributions on my pension.
Not sacrificing bonuses to pension (and instead paying 40% tax on them).

Anyone over 50 who hasn’t already, do make an appt with pensionwise (free govt advice service for over 50s).

I have just made repeatedly little mistakes my whole adult life. Never saving because there is always somehing I —need— want. It’s awful how I have just frittered money away.

I have equity in my house and an NHS pension so have those bases covered but I wish I hadn’t been so gullible with all the cheap credit around in the early noughties.

Buying a flat with a short lease...bought in a very popular area and we must be the only people to have lost money on property in that area.

Also getting into £25,000 debt by the time I was 20!

You’re not the only one leakycauldron. I bought a flat with a 14 year lease at auction. It came with an apparently served s42 notice to say renewal would cost £80,000. The s42 was fake. Turned out renewal would actually be nearer £200k. Had to sell at auction again because I didn’t have that kind of money to renew the lease. I bought it for £178k, renovated for £40k and sold at auction for £100k. The first solicitors (who faked the s42) did us over. I have always worked in law firms and never met a dodgy lawyer but property is another thing!
