Is it good practice to have multiple lines of credit in place?

[Dave Bopp]

Hey all-

During these uncertain times, is it good practice to have lines of credit established for each current rental property owned? On one hand it seems like an effective tool to protect against loss of rent situations and to have capital on hand when new opportunities arise. 

I've also read that the HELOC products were some of the first loans called during the last recession. Any guidance on whether to establish new lines of credit would be welcome!
