If you insist on DIY managing, you are in for a long and painful learning curve.

I'd venture to say that the percentage of valuble info, after you've ingested most of the content out there, is no higher with paid content then with the free content you will curate for yourself.  

@Michael Plaks Me too, but don't let that analogy carryover into promoting DIY TurboTax warriors haha.

The answers to those questions will help you determine how DIY you want to go, and how much you can leave up to chance.I can't post links here, but for more, please google:"Why you need an experienced ADU builder" - case examples where cities asked for tens of thousands of dollars of work, or flat out would not have allowed an ADU project, except for knowing when to push back"ADU sitework & utility costs: 10 hidden costs" - dozens of costs you need to account for on your ADU project that I promise you haven't thought of and no one else will tell you about"How to find ADU builders" - compares DIY route vs. other options, plus more on what to look for in a good contractor

Of course this does not work as does not count the remodeling added value which is the simple success key.That is good also for investors you could advice: I would plan a joint venture with them participating to the profit on a certain % (instead of asking a fee upfront), so you would remain with a % of a stable return, while your investor could finance back the money from the property and start over again.

One of my knocks on sites like BP is that it gives novice investors the illusion that they can DIY it and go up against an experienced Agent or seller without getting fleeced.

I would venture into markets in the mid-west, build a solid foundation, and start doing the BRRRR method.

Could be possible for a fix and flip hard money loan for a lender that ventures past single units. 

Like any business venture, you want to have the basics covered.

I didn't figure this out until I dug deep with our planning department while doing my due diligence before starting my venture.
