I'm hoping to find a house in the next 6 months and will apply for a mortgage then. My credit score is in the 830s. I'd like to get in on the Delta Platinum Business card but all my reading is full of dire warnings about getting a cc when applying for a mortgage. My question is: 1: Does this apply to high credit scores like mine. and 2: Does the fact that this is a business card change the equation at all?
