<prompt> Human: My mother is moving to USA and we need to build her credit up fast.I have great credit, but dont want to be on the hook heavily. Im considering putting her as an authorized user on one of my longest standing credit cards not giving her a card obviously, just so it shows up on her report instead of it being 100 blank, then co-signing a 3-5k auto loan for 36 months to keep the payment low for her and she can pay it off faster if she wants she will put 7k down.Once the auto loan books to her credit along with the authorized user, I would assume we can get her approved for a small 300-500 card with someone?Are there any other tactics we can use to get it going fast? Ultimately she wants to buy a house, but will need a mortgage, so I believe she needs at minimum a year and a few trade lines ie: car loan, credit card, maybe two credit cards.Ive heard starting from a blank slate can be tough. I never had that issue when I got my credit going in 2006 as they were handing out first time credit cards like candy!  <response>: She should get a card in her own name from day one, even if that means getting a secured card.As someone who went through the process of moving here, it took me about 2 years to get to 765 using nothing but credit cards. bought my car cash
