Rates for mortgages are in a constant state of flux, but they remain much lower overall than they were before the Great Recession.

Several key mortgage rates cruised higher this week. The average rates on 30-year fixed and 15-year fixed mortgages both saw an increase. On the variable-mortgage side, the average rate on 5/1 adjustable-rate mortgages also inched up.

Rates for mortgages are in a constant state of flux, but they remain much lower overall than they were before the Great Recession. If you’re in the market for a mortgage, it may be a great time to lock in a rate. Just make sure you’ve looked around for the best rate first.

The average rate for a 30-year fixed mortgage is 4.40 percent, up three basis points since the same time last week. A month ago, the average rate on a 30-year fixed mortgage was higher at 4.44 percent.

At the current average rate, you’ll pay principal and interest of $500.76 for every $100,000 you borrow. That’s an extra $1.77 compared with last week.

The average 15-year fixed-mortgage rate is 3.82 percent, up four basis points from a week ago.

Monthly payments on a 15-year fixed mortgage at that rate will cost around $731 per $100,000 borrowed. That’s clearly much higher than the monthly payment would be on a 30-year mortgage at that rate, but it comes with some big advantages: You’ll save thousands of dollars over the life of the loan in total interest paid and build equity much more quickly.

The average rate on a 5/1 ARM is 4.10 percent, climbing two basis points over the last week.

These types of loans are best for those who expect to sell or refinance before the first or second adjustment. Rates could be substantially higher when the loan first adjusts and thereafter.

Monthly payments on a 5/1 ARM at 4.10 percent would cost about $483 for each $100,000 borrowed over the initial five years, but could climb hundreds of dollars higher afterward, depending on the loan’s terms.

Forty percent of the economic experts polled expect interest rate to keep rising over the next week.

Derek Egeberg, a certified mortgage planning specialist and branch manager at Academy Mortgage, said, “Rates are going to be higher. Like the ‘Tortoise and the Hare’ story, you don’t notice the tortoise until it’s won the race, likewise, you won’t notice the slide higher in rates until rates begin with the next digit. Look for rates to meander higher at a tortoise’s pace.”

Mortgage planner Jim Sahnger of C2 Financial Corporation adds, “Rates have been pretty stable this quarter and, while I say we will be higher next week, I don’t expect by much. We have a lot of data, including the employment report, on the horizon and traders may be looking to protect themselves going into the release of the data. Couple that with trade talks opening up and the environment for bonds and interest rates could get a little heated.”

Shashank Shekhar, CEO of Arcus Lending, believes “Mortgage rates will move higher. There seems to be a sudden bearish tone towards bonds. The reasons are not that obvious though, but the potential deal on NAFTA could be the trigger. With less uncertainty, money flows from safe instruments like bonds to riskier one like stocks. However, a stronger dollar will continue to support bond prices. With the pressure on bond prices, the mortgage rates could trend higher, but the change may not be significant.”

Michael Cox, Founding director and executive-in-residence of the O’Neil Center for Global Markets; Freedom SMU Cox School of Business and former chief economist of the Dallas Federal Reserve Bank,” has a different view. He said, “Rates will be down slightly this week. Investors’ fears of rising inflation have subsided a little as expectations are that economic growth will not continue at last quarter’s fast pace. A rising trade war with China is increasingly hurting the economy, slowing the growth outlook and dampening expectations of businesses’ investment demand. These factors add up to an expectation of somewhat lower rates in the future, which takes rates down slightly now.”

However, 47 percent of the experts poll believes rate will hold steady.

Logan Mohtashami, a senior loan officer at AMC Lending Group, said, “Once again, the 10-year yield held up at the bottom portion of the range and still has been stuck for most of this year between 2.78 and 3.05 percent. This tight range can’t last forever so the key will be finding out what makes us break higher or lower. For now, this range has been a tough break. Even with the possible trade deal in hand with Mexico and Canada, GDP revisions up to 4.2 percent, not much is going on in yield.”

Dick Lepre, a senior loan officer at RPM Mortgage, said, “Rates will be flat. The techs have not been asserting either bullishness or bearishness for Treasuries. No help from them in regards to forecasting movement. Whatever drives Treasuries in the near term will not be technical and will likely be driven by events in other nations.”
