Edit: Found him, his name is Scott Tucker. Watch Dirty money on Netflix, it's a very informative docu-series.
Awesome, I hadn't noticed that in the god-awful Netflix display page of their movies and TV series, and I appreciate you taking the time to mention it. I just found it and am going to watch it, probably after this post.
I'm not familiar with loan apps, but based on what I know about hard money lenders, payday lenders, and the like I'm sure OP's friend got ripped off somehow. Those services are basically the worst form of usury, and they really should be illegal in the US. I'm not even sure how they're regulated, but even if they are they're profiting from desperate people and that leaves a bad taste in my mouth. They're worse than drug dealers.
I was always brought up by the rule of "live within your means."
Everyone should do that, but you and I both know what the reality is. I don't know about other countries, but in the states everyone has a credit card, and a lot of them are maxed out. People buy homes that they're slaves to based on their mortgage rates and cars they have to finance, etc., etc. The rule that I've stuck to for the last 20 years is if I can't buy it with cash, I don't buy it. Saves me a lot of headaches.
