The simple, but annoying answer, was luck and fear.

I grew up in poverty on account of my father going to prison very young and my unprepared mom having to somehow take care of 3 kids and realizing he had made lots of money vanish and stolen lots of the money we did have that needed to be returned, and instead of inheriting money irresponsibly, I got a crippling fear of debt and spending money on non necessities.

But at the same time I was making around 70k a year at 25, because at 20 I got my associates in IT, then found a job paying above what I was asking for in under a month after graduating, and I still work at that job 10 years later as they've been very reasonable through everything. Getting that job SOO fast that worked out so well was just pure luck.

Also I couldn't buy the house I'm in anymore, buying at 25 instead of 26 was pure luck. If I had been born a year later, buying at 25 wouldn't have worked. The price of the house went up about 100k a few months later.

Also even in 2019, my home was considered a fantastic deal. A 2k square foot town home for 240k in a medium sized city (the one I grew up in), within walking distance of main street. It has an hoa, but it only has 9 other town homes in it, and we have a massive shared common area and pool. Having a pool I only have to share with a dozen other people is a luxury I never imagined. Hoa fee is 200$ and they've only ever asked me to pull weeds around my house when a neighbor was selling theirs and they wanted it to look pretty to help out a neighbor.

So I actually don't have a car (too expensive) and I can walk/bike to grocery stores, doctors appointments, the like. To top it off it's only about 3 miles from where my mom lives, and we just recently moved my grandma into a senior living center about a mile away so she's close to me and my mom.

So, yeah. I just saved every penny to a stupid level, then got rather lucky. Saving every penny at my income wouldn't have worked without the luck. Never being unemployed in my entire life was pure luck. Finding a home that met all my needs perfectly within my budget was crazy.

The cheapest home in this city are 200k 900 square feet town homes, but because of the interest rates the monthly payments are 50% higher than my beloved home.

But all that luck wouldn't have meant a thing if I hadn't saved like crazy. Sooo... yeah. For context, after much cajoling from counseling I have agreed to allow myself 100$ fun budget per month, and $400 a month for food so I buy more "nice" food. My only debts are a little bit of my college loans (I paid off all the high interest ones and the only ones left are like 3%. I had a tradition where every tax return I just put the entire thing towards the highest interest student loan) and my mortgage which is at 4.25%. I'm going to retire a millionaire and with a fully paid off home.

But it's so sad, because people taking the EXACT same actions as me, but 2 years younger, won't. They'll have to rent their entire life, or buy a home out in the middle of nowhere away from family and services. Which means they'll most likely need a car and have to pay other premiums.
