You're lucky that you didn't have any hiccups in your income that would've been problematic for most people. And you're lucky you were born when/where you were. You were able to lay the foundation for your life in a unique time period in history where it was much easier for an average person to thrive than it has been any other time. I don't begrudge anyone for when/where they were born, and I applaud you for taking advantage of it as much as you did. I also don't want to trivialize the sacrifice of your service and the perks that you earned as a result. You did what you could with what you had and that's a credit to you. But that doesn't mean that the techniques you used are just as likely to succeed today as they did decades ago in a much different environment.
I can find no info to back up your claim that loans with smaller down payments have fewer defaults. Everything that I see seems to show the opposite is true. That data is a bit dated, but it shows that loans with a downpayment between 0-5% have a default rate around 16%. Loans with 20% down payments default at a rate closer to 6%. For those that put more than 30% down, the rate of default drops below 2%. Suggesting somebody take out a mortgage with a small down payment, without acknowledging the significantly higher risk of default in those situations is irresponsible. Can it be done? Sure. Should it be done? In my opinion, Only as a last resort.
