A number of closely-watched mortgage rates trended down in the Detroit area this week.

Key 30-year rate falls in Detroit

The average rate on the benchmark 30-year fixed-rate mortgage rate for the Detroit area fell to 4.03 percent, according to Bankrate’s national survey of large lenders. The local rate was less than the national average rate of 4.09 percent, and was down 5 basis points from last week. A basis point is one-hundredth of 1 percentage point.

For mortgages in this week’s survey, there were an average of 0.34 discount and origination points.

The drop in the 30-year fixed is great news for those who waited to lock on a rate, as their gamble paid off.

Monthly payments on a hypothetical $165,000 mortgage slid to $790.59, dipping $4.76 from last week, corresponding with the decline in mortgage rates.

No clear direction for other Detroit mortgage types

On the other hand, the average rate for 30-year jumbo mortgages trended upward this week, rising 4 basis points to 4.13 percent. Jumbo mortgages are used for loan amounts above limits set by the Federal Housing Finance Agency; for the Detroit area, that limit is $424,100.

The average rate for 15-year fixed-rate mortgages slipped 4 basis points, dipping to 3.35 percent. Monthly payments on a hypothetical $165,000, 15-year fixed-rate mortgage followed rates ticking downwards, down $3.22 to $1,167.44.

The 15-year fixed is a popular mortgage for homeowners who want to refinance. With this downward trend in the 15-year fixed, a refinance will be more attractive to some homeowners.

The popular 5/1 adjustable-rate mortgage rate ticked upward to 3.48 percent this week, a rise of 2 basis points. 5/1 adjustable-rate mortgages allow property owners to pay a fixed rate for the first 5 years, and the rate adjusts once per year every year after. They are the most common variety of variable-rate mortgage.

Methodology: The “Bankrate.com National Average,” or “national survey of large lenders,” is conducted weekly. To conduct the National Average survey, Bankrate obtains rate information from the 10 largest banks and thrifts in 10 large U.S. markets. In the Bankrate.com national survey, our Market Analysis team gathers rates and/or yields on banking deposits, loans and mortgages. We’ve conducted this survey in the same manner for more than 30 years, and because it’s consistently done the way it is, it gives an accurate national apples-to-apples comparison.
