You are truly bought into the credit score scam.
Get a credit card, buy groceries once and spend the next year paying off the card and that means you are worthy of more credit.
Pay your rent on time for 5 years and it counts for nothing. Even though it shows far more reliability than the credit card.
Biggest scam around.
My 27 year old daughter has a credit limit of 70 grand on her card. For the past two years every time she is able she ask for a higher limit. She has about a 10 grand running total on it due to the travelling she does for work. She pays off the old and add new. It is not her money, it is her employer paying her expenses. Does this make her a better candidate for owning a house than someone that has faithful paid all their bills and rent on time for the past 5 years?
She would laugh at that idea.
