Is getting a credit card before mortgage bad?

[Ronald Mejia]

Hey BP!

I was recently told my credit file is "too thin". Ive paid off all of my student loans, car loans, and credit card balances so im sitting at a zero balance. My current credit card only has a $500 limit on it and i pay it off every month. I would like to purchase a property in the next 6 months.

Would it be beneficial to apply for a 2nd credit card to increase my overall credit limit and add some history to my file or would that hurt me? 

Thanks!
