Credit Score Management

I don’t have a lot of credit, and I have applied for several credit cards, but always get turned down. Is there a credit card that takes approves someone that may not have alot of credit like me? My score isn’t even 600…

I am in need of repairing my credit. Anyone knows a excellent company that can help me with this?

I have a credit score of 618. Is this enough for me to apply for a home loan?

Any thought how much it costs to have a credit repair company try and fix your credit report

Basically, my mom is going to be looking into buying a house soon. She wants to check her credit score. Which score is the actual one necessary to check? I’ve seen FICO and all types of other general “credit scores” that could be checked.
Which does a mortgage company look for, and just how many different “types” of credit scores are there? I know that a credit score is a summary of the creditworthiness based on one or up to all three of your credit reports. But where is the safest, cheapest and most reliable place to buy a credit score online?
