Heloc on rental properties

[Dan Leaman]

hello biggerpockets community,  I am looking for information regarding Heloc's on rental properties.

Who offers them?

Pitfalls I should be aware of?

Helocs vs cash out refinance?

I own property outright have a solid tenant and I have equity sitting there staring me in the face daring me to use it somewhere else.  I am looking for options that do not require selling my unit. 

Any heloc specialists here?

Many thanks in advance.
