Buying a 2nd income property- HELOC?

[Mike R.]

Last year in April I bought an income property cabin in Big Bear Lake, Ca. I paid cash so I own it outright. It has been doing very well in rentals so I want to buy a 2nd one. 

I can't pay all cash this time- so I was thinking of taking out a Home Equity Line of Credit against the first house. Would be the best way to get another $100k or so to buy the new house with? 

If so- is there a good place to start? Just go to my bank? I have a Credit Union but there's is a variable interest rate over 30 years (No penalties for early payback- which is great) but I don't like the idea of a variable rate. 

Would love to hear thoughts on HELOC as well as any other thoughts on taking out a $100k loan (I will pay around $75-$125k cash)
