Mortgage rates for 30-year loans are now at their most expensive level since early May of last year. Most other new purchase loan types increased as well.

The average rate on a 30-year mortgage in the U.S. climbed this week to its highest level since mid-February, a setback for home shoppers that threatens to slow sales further this spring homebuying season.

As you consider buying a home, you’ll likely weigh different mortgage types. For most prospective buyers, a 30-year fixed-rate mortgage is the top pick. It offers more manageable monthly payments because you’re stretching the loan over three decades as opposed to 10 or 15 years.
