It's good to use a few different credit report websites to check your credit score as sometimes the credit score can vary from place to place.
Although ranges vary depending on the credit scoring model, generally credit scores from 580 to 669 are considered fair; 670 to 739 are considered good; 740 to 799 are considered very good; and 800 and up are considered excellent.
It's recommended you have a credit score of 620 or higher when you apply for a conventional loan.
If your score is below 620, lenders either won't be able to approve your loan or may be required to offer you a higher interest rate, which can result in higher monthly payments.
