You can't have a ton of them, but if you have a have a paid off $100,000 property that cash flows $500 a month (rough use of the 50% rule) AND you have a HELOC where you can indefinitely borrow $80,000 and pay ~5% interest only payments for the first 10 years (I'd pay it off more quickly and use it again and again), does this pencil out to be worth it?  

(I mean as a way to cover capital expenses that you didn't plan for at the onset, not to cover negative cashflow indefinitely) At least, until you have enough set aside to feel comfortable. 

If you’ve got cash to hold onto a property indefinitely and wait for appreciation I don’t think it’s a bad place to invest in.
