30-year mortgage rates

The average 30-year mortgage rate today is 3.097%, up 0.011% from yesterday. At today's rate, you'll pay principal and interest of $427.00 for every $100,000 you borrow. That doesn't include added expenses like property taxes and homeowners insurance premiums.

20-year mortgage rates

The average 20-year mortgage rate today is 2.714%, down 0.003% from yesterday. At today's rate, you'll pay principal and interest of $540.00 for every $100,000 you borrow. Though your monthly payment will go up by $113.00 with a 20-year, $100,000 loan versus a 30-year loan of the same amount, you'll save $23,978.00 in interest over the course of your repayment period for every $100,000 you borrow.

15-year mortgage rates

The average 15-year mortgage rate today is 2.354%, up 0.012% from yesterday. At today's rate, you'll pay principal and interest of $660.00 for every $100,000 you borrow. Compared to the 30-year loan, your monthly payment will be $233.00 higher per $100,000 in mortgage principal. Your interest savings, however, will amount to $34,876.00 over the life of your repayment period per $100,000 of mortgage debt.

5/1 ARMs

The average 5/1 ARM rate is 2.958%, down 0.054% from yesterday. With a 5/1 ARM, you're only guaranteed your initial interest rate for five years. From there, your rate will adjust once annually. That could mean having it fall, but there's also the potential for it to rise. Since today's fixed-rate loans are so competitive, it could pay to lock in a guaranteed rate for the life of your repayment period rather than risk your rate rising over time, as would be the case with an ARM.

Should I lock in my mortgage rate now?

A mortgage rate lock guarantees you a specific interest rate for a certain period of time -- usually 30 days, but you may be able to secure your rate for up to 60 days. You'll generally pay a fee to lock in your mortgage rate, but that way, you're protected if rates climb between now and when you close on your home loan.

If you plan to close on your home within the next 30 days, then it pays to lock in your mortgage rate based on today's rates -- especially since they're very attractive, historically speaking. But if your closing is more than 30 days away, you may want to choose a floating rate lock instead for what will usually be a higher fee, but one that could save you money in the long run. A floating rate lock lets you secure a lower rate on your loan if rates fall before you close on your mortgage. While today's rates are very low, we don't know if rates will go up or down over the next few months. As such, it pays to:

  • LOCK if closing in 7 days
  • LOCK if closing in 15 days
  • LOCK if closing in 30 days
  • FLOAT if closing in 45 days
  • FLOAT if closing in 60 days

If you're thinking that the time is right to apply for a mortgage, contact a few different lenders to see what rates they offer you. And don't forget to compare closing costs, too. Your ultimate goal should be to keep those fees to a minimum, all the while snagging a great rate on your home loan.
