Money Makeover - How can I plan to retire in my 50s?

In theory, yes.

I personally know exactly zero Irish people who have ever done this.
Waves. My only problem now is that I want to put the money back into property in Ireland. That's been a massive fail so far. But just today my sibling told me of 3 properties in 2 locations we had been looking at that went sale agreed too high for us that have gone back on the market, to our surprise, one or two, but three. So maybe if we hold out a while longer ......... Maybe the property I really wanted that went +/- 30% over asking will also fail to go to sale completed.

One of my siblings sold their large PPR to downsize way before retirement and freed up the equity from the PPR meaning a low mortgage rather than a massive one, plus less headaches of running a large home. My mother sold her PPR to invest in other property and give her a retirement income as she had no other income.
 
56... and counting.
Your post was very interesting. Thanks for sharing. The corporate world and your experiences of it we have lived thru with my husband.

This in particular resonated with me:

I observed and learned from this behavior for years, and saw some of these colleagues ruthlessly axed as they became too expensive or too much of a threat to their manager. This was a real motivator to ensure that I did not develop a financial dependency on any corporate organization.

Thank goodness I developed our own property portfolio for when the axe came. I was always terrified of being too reliant on the corporate salary. I wrote a post on here about it once but deleted it as it was too outing. And like you I started in property in my twenties. 10% deposit and most of that borrowed without telling the bank. I'm intending to encourage one of my children into the property business by giving them an opportunity to renovate a property for me and see if they like it. Might get the bug.

 

I've heard the rhetoric before that you'll not become wealthy being a PAYE worker in Ireland. I think in reality what they mean is they won't become rich quickly.

As you point out there are plenty of PAYE employees who are wealthy.
 
I know it's probably covered in one of your points but I would add, 'Stay single and don't have kids' .....
