Mortgage refinance rates are typically higher than purchase rates, but various factors can influence the final cost. A 30-year fixed mortgage offers lower monthly payments and predictability in payments, while a 15-year fixed mortgage has lower interest rates, though higher monthly payments. Adjustable-rate mortgages provide lower introductory rates but come with the risk of future rate increases.

The national average 30-year fixed rate remains high at 6.74%, but differences may exist depending on location. Refinancing could be beneficial if one aims to secure a lower rate, improve credit, or shorten the loan term. Economic factors and market trends may also affect future mortgage rates.
