When I help new investors with buying their first property I often want to know what is holding them back from pulling the trigger.So I'll ask here. What is holding you back?

After listening to the Clayton Morris podcast (EP115 with Mike Banks) about the company Fund & Grow, I became intrigued with the idea of using business credit cards to buy rental properties using the BRRRR method....

Just curious what other investors think. Is this just another hype deal or is this a new reality for possible rent collection?
Side note, I tried to sell a house for bitcoin in 2013 with no takers or even one response.
