Refinance activity grew modestly in September, according to a report from Ellie Mae.

Ellie Mae said in its Origination Insight Report released Wednesday that refinances increased to 45% of all closed loans from 43% the month before. At the same time, the 30-year note rate dipped to 3.75% from 3.77% in August.

Corresponding with the uptick in refinance activity, the average time to close all loans rose to 48 days from 46 days in the previous month. For refinances, the time to close was 50 days, while it was 47 days for purchase loans.

Ellie Mae also noted that it took 49 days on average to close an FHA loan and 51 days for an FHA refinance. The time to close a VA loan also rose to 51 days.

While times to close increased, FICO scores remained unchanged at an average of 731 overall, 754 for conventional purchase loans and 747 for conventional refinances.
