I'm about a month into a self-funded search. The basics are in place, and I know plenty of work lies ahead before I find a deal worth pulling the trigger on. I'm not chasing perfection, but my working assumption is that even good-enough deals are rare, and that edge comes from being bale to move fast when one appears. Forget podcasts and book lists - that's covered. I'm after the stuff that only experience teaches: the "wish I'd done that one quiet Thursday afternoon in month 2 or 3" kind of prep that would've saved you a ton of stress - or even a lost deal - once things got serious and you had to move fast. What's one thing you kicked yourself for not having ready sooner?
