Average mortgage rates inched up Thursday, with most loan varieties climbing just 1 or 2 basis points (a basis point equals 1/100 of a percent). The news was better for people shopping for a jumbo fixed rate alternative. (A "jumbo" loan is generally required if home buyers need to borrow more than $417,000.) The rate on those larger loans dropped another 4 basis points, which tacks onto the previous two days of drops for a combined 28 decline.

Would-be home buyers in the market for a 5/1 adjustable rate mortgage (ARM) weren't as fortunate, given today's 5 basis point increase in rates. The 15-year fixed loan also rose, albeit a slightly more modest 4 basis points. In all, mortgage costs generally remain in line with last month's levels.

Here are all of today's average mortgage rates across the U.S., along with where they stood a month ago .
