The rates you see here generally won’t compare directly with teaser rates you see advertised online, since those rates are cherry-picked as the most attractive, while these rates are averages. Teaser rates may involve paying points in advance, or they may be selected based on a hypothetical borrower with an ultra-high credit score or taking a smaller-than-typical loan. The mortgage rate you ultimately secure will be based on factors like your credit score, income, and more, so it may be higher or lower than the averages you see here.
