Hi Deb- There is some good info on this right on Trulia. though it does not say exactly the DOMs, etc.
But you can make some estimations from the data. Seems like 10-12 weeks would be an average DOM for the Town.
That doesn't mean you close in 10-12 weeks. Means you have a signed P&S. From there, its probably 35-60 days to actually transfer and close.
If you need any other help, feel free to contact me. Thanks,
