financing a vacation home

I own a house on long island. Just took out an equity line of credit for 150,000. It is adjustable. I was wondering if I could apply for a loan for a vacation house and not use my line of credit. I would like to purchase fix up and sell with that. My credit score is 680. I can not show income. My first mortgage is for 260,000. My house is appraised at 550,000.
