new to BRRR... how many refi loans to you actually have?

[Keith A.]

One fear I have with BRRR is having refi's on almost every property. I am a slow investor... I HELOC my primary, buy a rental, payoff the HELOC, buy, repeat. I don't like more than 100k out at a time. Multiple loans would give me anxiety... what if all properties went vacant for several months? Do all who BRRR have enough capital to withstand the bad times? Does anyone fear crashing and burning at some point if something unforeseen happened such as 2008? Perhaps I am not entirely understanding the concept, but as I read it, it is continually cash-out refi'ing rentals to buy new rentals as the equity builds... repeat repeat. How many refi loans (or any time of loan) do you have going at one time? Thanks for the input!
