BRRRR...Debt to Equity

[Douglas Curtiss]

I'm interested in starting a longer term portfolio of rentals using the BRRRR strategy. My concern though is by pulling equity out of each property, I'll eventually have 5, 10, 20... properties all leveraged. Of course I would use the calculators to make sure they would cashflow well and that the mortgages would be paid down. My concern is if the market takes a downturn and the mortgages go underwater. If the properties are cashflowing, one can ride this out to an extent, but I would be stressed to have a ton of debt in a down market. So I'm curious what other investors use as a rule of thumb for debt to equity.

@Kevin Sobilo, finally had a chance to read your response.  I think I like that approach.
