Pulling equity from a mortgage free rental

Hi all !

I own two rentals mortgage free.  I am unemployed other than my rental income.

If I walk into my local bank , how would I proceed with this? 

I would like to pull out the equity value from one of my rentals.  How much would this amount to , the value on zillow ?

If I would use this cash on another rental , I would own that rental outright ? 

I just would owe the equity amount on the house I pulled equity from ?

Will a bank always give equity loans ? 

Will they ask about employment status ?

My credit rating is excellent .

Thanks
