To get more traditional mortgage loans, your credit scores need to get above the 620 to 640 range. If you want to get the best interest rates, you need to raise your credit score into the 740+ credit score range.
For a cash-out refi on a home the borrower lives in, generally, the lowest credit score is 640, according to Fannie Mae's standards. But such a loan comes with caveats. The borrower can't have an LTV ratio higher than 75%, must have 6 months of reserves in the bank and a debt-to-income ratio of 36% or lower.
