HELOC/2nd mortgage for Private Student Loans at 12%

[Ricardo Escobar]

Greeting Everyone, 

new here and trying to weigth my options: 

 wife currently has about 15K in private student loans at a 12% interest. current payment of about $225.00 is mostly going into interest. 

i am trying to clear the way fast from debt to move onto bigger better things such as of course real estate/rental properties. 

we have received a few quotes on HELOCs (Current equity about 70K) with an interest rate of 3.4% for first 6moths and then 6.4%.

we are planning on aggressively attacking this debt. 

does this plan make sense?
