You do not need to try it. It will not help your credit to take on more debt. It is a very bad idea to take out a personal loan to pay back a company debt. Why everyone on this thread isn't yelling this at you in all-caps is a mystery to me.
You have the tone of trying to keep the house from collapsing until the parents get home.
Go to a local credit union instead of a big bank. You can probably also use your car or other assets as loan collateral. I'm sorry to hear you're going through this. The best of luck to you.
You need to try it or you'll never know for sure...
