Many seasoned manufactured home investors are very aware of this financing concept and are open to the idea.

You and everyone else should join your state manufactured housing associations, because they are a valuable source of information.

I plan on contacting the Oklahoma Manufactured Housing Assoc tomorrow.

Many citys / states will keep the install records, so you should be able to go to the records department of the city, county or state and see who set it up and to what plan (manufacture, new engineering or state mandated) they followed. 

There isn't much published online, but I plan to call the housing voucher programs serving some of my target neighborhoods and just ask them manufactured homes qualify.

Since its early 1900s and it has the last brick of the Towns brick manufacture could it be historical?

The one thing I found that would produce Cash Flow was with Manufactured Homes in San Jose.

At the wholesale level direct from manufacturs a park can buy a nice 14'x80' 3/2 for $19k  Yes I'm not fibbing.  

I've had my agent pull the comps, and I've read some great information on this site on estimating ARV, but I'm not confident in the number I come up with (my agent says it's"good value" but that doesn't help me as a newbie investor to verify the numbers).There are some problems with the comps as far as I can see: The house is a manufactured home (on a PRIVATE lot of 10,800 sq. ft, which comes with the sale) but I can't find comps that take that into account.

An opportunity has come across my path to purchase a manufactured home for fairly (really) cheap - I also happen to be needing a new living situation soon.
