Reddit is good for things like getting out of credit card debt, how big of a mortgage should I take, and other basic personal finance stuff.

However I've seen some pretty bad advice thrown around when it comes to investing.

Bogleheads is a much better resource for that.

Going to echo this one. Plus the following two books: 1/ Richest man in Babylon 2/ Rich Dad, Poor Dad.

Both written for the simplest of readers but great advice clearly told.

(Summaries are probably good enough)

Summary of Rich Dad, Poor Dad:

Assets are things that give you money. Liabilities are things that cost you money. Therefore your house is a liability until it is sold, at which point it MIGHT be a net asset. Try to maximize your assets and minimize your liabilities.

It sounds simple, and it is, but that's the primary lesson in the book IMO. It's eye-opening the first time you see things that way.

The greater point is if you become a landlord, you get rich with the bank's money.
