Good/Bad? HELOC per property for emergency repair costs

[Adam Peacock]

Greetings BP fam,

As I continue to build my portfolio, I understand investors should be baking a cash reserve into the cost of a rental's cash flow equation to cover planned/expected costs such as roofing or water heaters. For unexpected and uninsured costs such as damages due to things like tenant negligence, roof problems or any other non-insurable liabilities, does anyone have feelings or opinions on setting up a HELOC for each non-commercial investment property (where possible) to limit the impact of these unexpected expenditures? Where equity exists, the thought occurred to me that a HELOC against each property could be beneficial to lessen the impact of paying unplanned costs.

Thoughts?
