<prompt> Human: First off, I dont have much knowledge regarding real estate and was looking for a second opinion. My dad registered a real estate business under me and my sister and is trying to buy and sell property. I am very young 18 and I dont know the exact details of whats going on and only went through with it because hes my dad. Today he told me we were going to a bank to withdraw and borrow money and I asked what kind of loan he was taking. He said a home equity line of credit. I asked him how he was going to spend and pay it off and he said buy and sell houses. I dont know what questions to ask or what to say about it. He recently lost his property as collateral which he had a used car business and I dont trust him because I know how much I will be affected if he fails to pay the loan. What should I do?  <response>: That sounds like a horrendously horrible idea. Looks like your dad is getting ready to ridiculously screw you over.
