@Jared C., a few other points. As a beginner, I would suggest waiting until housing prices and rates have stabilized a bit, so you're dealing with fewer moving parts. It's very easy to spend your money but getting it back, not so much. I'd also consider doing a flip before trying a BRRRR because it can be a little more forgiving re: budget miscalculations, bad contractors/subs and time overruns.
Someone above said it but I'll repeat, finding a property that's significantly undervalued usually means it's an extensive rehab or gut. You really should avoid those deals when starting out. Finding a small flip needing lighter rehab, that nets 10% – 15% while gaining valuable experience, is not a loss.
Hard money has its place but the reality is most of my budget savings are found in using cash (or private money), using a GC for as little of the project as possible and directly managing all the trades/subs. House hacking on a primary residence with a one-close construction to perm loan is a cheaper option too. The process is slower with a one-close CTP but cheaper.
It takes time to find a team of quality GCs and trades. Once you find people who know what they're doing, you then have to find further filter that group and find those whose personality and work style meshes with yours. And if you don’t know what you’re doing they’ll ignore or dismiss your suggestions. To manage trades yourself, you need some experience (2 – 3 projects) to correctly assess a project, create scopes of work for each activity, bid it all out, create a realistic schedule and do constant QC throughout the entire rehab. It isn't something I'd suggest for someone new.
Realistically, the first few times, you’ll probably use a GC for your entire project. GC plus using hard money makes it much harder to finish up with 25% equity, which is why you might want to try a flip first.
Finding a mentor or taking less to shadow a project, sort of as an apprentice, would help. Attending all the inspections helps you learn a ton too.
