What is the average turn around time for completing a home loan
refinance transaction?

There are obviously a lot of factors that determine how long it will
take.  Most sites agree that 2 to 4 weeks is a good average.  A few of
the sites seemed to think it would take longer while one mentioned as
little as 10 days.  Several of these sites have good information on
some of the factors that can determine how long it might take for your
case.

The mean average is ~ 3.5 Weeks
The mode and median average is 2-4 Weeks

If you require any additional information please post a request for clarification.

Thanks!
