Mortgage Paid off - HELOC?

[Vernon Huffman]

I'll keep this basic as we are just now in our education phase. Home and property are paid off. (Value $220,000) We live in a decent market for B, C and D properties. We're looking into duplex/quad and/or potentially a SFH to get started. I have a 9-5 that I will keep. Would it be beneficial to take the HELOC or Cash out Refi route? The only debt we carry is for the wife's car. Or should I Dave Ramsey it and just save? Any of your thoughts would be appreciated. Thanks much.
