If you want a lower downpayment way of investing without moving into the property, I recommend the BRRRR method. 

Your problem is probably your method of wholesaling. 

I decided I’d find another method. 

What is the most efficient method to connect with potential renters or claims representatives?

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

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. 

So, some food for thought.Trusts seem to be the preferred method of liability and asset protection among the wealthy.  

Not when there are so many alternative methods of engagement towards resolve of which past clients have appreciated.

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

As you know there is no equity in this method, BUT it gives you money to go purchase that equity.
