Student loan payouff with Home Equity Loan etc.

[Drew Slew]

There has been a few threads on this topics, just wanted to gauge anyone's suggestions who had similar situation, or is an investor understanding HELOC/home equity.

- i have a 30k student loan at 6.25% interest, monthly around $500 payment.

- i have a 115k mortgage that i put 30k down in a 145k home, by now its 35k paid off total. interest is around 3.5%, 30yr fixed. This is a first mortgage, bought place last June, 2016. (not 1 year of full ownership yet, but prolly have 25% of home value by now)

- good credit, not much CC debt and no other debt, around 25k savings cash.

Options: 

- either pay down the student loan with a home equity loan around 3-4% if possible, take out 50k home equity loan, 30k for student loan and 20k id throw to my 25k cash and buy another rental

- leave everything as is and just take out 20k home equity loan to boost up cash and get another property around 200k for a rental investment

ANY IDEAS appreciated, and even happy to connect to tax CPA-s in New Jersey area.
