Today, some mortgage interest rates have increased slightly while others have decreased. The average 30-year fixed rate is up to 6.47%, but the 15-year fixed rate has gone down to 5.66%. These rates are national averages and rounded to the nearest hundredth. Mortgage refinance rates are also provided.

The main advantages of a 30-year fixed mortgage are lower payments and predictability. However, the main disadvantage is higher interest rates both short and long term. On the other hand, a 15-year fixed mortgage offers lower rates, predictable payments, and the ability to pay off the loan sooner.

Adjustable-rate mortgages (ARMs) lock in rates for a set time before changing periodically. The introductory rate is usually lower than a 30-year fixed rate, leading to lower initial payments. However, rates can increase later, making monthly payments unpredictable.

Now is a relatively good time to buy a house with steady mortgage rates since the end of August. Trying to time the market is futile, so buy when it’s right for your circumstances. Economists don’t predict significant rate drops soon. Mortgage rates vary by location, so consider local factors when buying.

Securing a low mortgage refinance rate is similar to buying a home. Improving credit scores, lowering debt-to-income ratios, and choosing a shorter term can help lower rates. Refinancing into a shorter term may result in a lower rate but higher monthly payments.
