Keep cash or pay down mortgage

[Austin Klesmitk]

I currently have a mortgage on my personal property at 3.4% interest with around 100k in equity.  I have around 30k saved at the moment and I am looking for a single family home to turn into my first rental.  My question is should I keep the cash in my savings account until I get a deal under contract or should I put that 30k towards my home loan and when I need it pull it out via heloc?
