Best use of cash and home equity for a down payment?

[Sarah Mueller]

Newbie here. I'm trying to decide the best way to fund my first deal. 

I've got about $20k in cash to spend and up to $164k in equity on my personal residence. I also have a car loan for $8k. I'm wondering if I should pay off the car loan and use the remaining cash and a portion of the equity for a downpayment on a duplex. Or should I keep the car loan so as to have more cash available?

I'm looking at properties between $70k-$150k.  

Thanks for your help!
