Couple questions about student loans and credit

J

Hello, my name is Jessica, I am 25 now and will be finishing school now..

Couple questions about student loans and credit.

So, do they affect the credit score?

I don't have any job right now, and I am constantly looking, how much time will I have to start paying them off?

I will have around $40,000 total of debt and just want to see how it will affect my credit because I plan on buying a home in the next 3 years.

Do student loans will hurt my credit?

Will I need to hire a a credit repair company so I have a score of 700 at least?

Lets say I find a job at 80k, how much should I pay them off?

Not sure what the interest is.

Anyway, thanks! and I hope I am in the right category!
