You have to establish credit. One way is to obtain a loan through a furnature store or auto dealer. You purchase an item, and even if you could pay cash, take advantage of 'no interest for three months' or other such items to make payments on the item. This will build up a credit rating. One or two credit cards, (Not dozens!) with prompt pay-offs, is always a good thing. If you are renting through a large property management firm, they may report your rent payments to the credit bureaus.
