One of the things that I have been told is to make sure I do not touch my principal.

Living for free, paying down principal and getting big tax benefits should be enough motivation.

It's actually one of the most economical loans you can take out, since you are paying YOURSELF the interest as well as the principal.

It's a much simpler transaction there: "I get X% per month from investment, I pay Y% to the HELOC servicer" The only risk I see is losing my principal. 

I then put 100% of the line of credit towards the principal of the mortgage. 

Remember you principal and interest payment is only the beginning of your expenses.

You will face higher payments though because of Principal Insurance and because investment loans have higher interest than residential.

I spoke to a lender about the no seasonings cash out refinance and here is what I was offered: 4.75% 30 yr fixed  possible loan 105,000, principal and interest and tax $700.Is this a good deal?

If all goes as planned, I will be purchasing my principal residence in 2017, and investment #1 will come ~12 months later.
