I have lost the title to a newly purchased manufactured home. I live in Michigan and can identify the home by the product tag. Can I get info on the internet.

Not on the net. You will have to go to the County Title office and get a duplicate replacement if the title is in your name. The product tag as you refer to it is actually the home's serial number. The county can track your title through the serial number. It probably will cost about $10 for a replacement title.
