It was a fairly uneventful day for mortgage rates to start the new week. The underlying bond market was slightly stronger. This suggests slightly lower interest rates. The average mortgage lender lowered top-tier 30yr fixed rates by 0.01% compared to Friday.  Underlying motivation for the bond market can mostly be attributed to lower oil prices, which have been a common source of intraday inspiration for better or worse. With today's drop, the average lender remains right in line with the rates they offered before last week's Fed rate hike.  [thirtyyearmortgagerates]
