One of the methods I plan to utilize is to list the space on craigslist.

Often times when a builder/buyer moves too fast, or is too busy and overlooks a key piece of due diligence, the unethical ones will try the "scorched earth" method and blame everyone but themselves, even when they know it was their own mistake, and they'll see if they can scare you, the seller, the title company et al into paying damages/fixing their problem. 

While many gurus glorify the strategies they’re selling through courses or books, methods like out of state investing aren’t easy and can put you in a tough financial spot if you’re not careful.

Additionally, are there any other methods, approaches or strategies you’d suggest for someone just starting out in this space?

Your problem is probably your method of wholesaling. 

I decided I’d find another method. 

They really do not know how to decipher what is a question posed to get business, then they end up with an inbox full of DMs.A lot of us have started using the "nice" call-out method, which involves responding something like, "I see you are an agent in Dayton asking a question about housing in Dayton. 

That’s our primary method of communication so it works.

Bandit signs, cold calls/texting along with direct mail is the method most people use.

The BRRR method is not about "numbers working" in a given market.
