It is amazing at how much some Manufactured Homes / Mobile Homes cost in Parks where the lot rent is anywhere from $300-600 per month.  

Thanks for the welcome.My company specialized in data collection and analysis in manufacturing and warehouse environments.

In areas such as southern California where we have perfect year round weather, all of the Forbes list companies have offices, high tech, low tech, manufacturing, medical centers, universities galore, amusements, sports venues, zoos, beaches, etc. there is ALWAYS going to be a high demand, thus higher prices.

When contractors buy from Home Depot, they pay 125 which includes a markup and limitations in sizing, but Crystal manufactures their own so no frame ins.

before you pick up the cabinets from the manufacturer make sure all doors are straight and there is no 1/4' gab between them. just cut thru cardboard boxes and take a look. less pain afterwards with your installer.

The manufactures have charts that answers your question. 

One thing we never lost was culture, we are seeing a massive renaissance in our communities across the entire Greater Cleveland Area.Yes, we have amazing infrastructure stretching from anchor facilities such as major medical systems with integrated learning and university elements, public transportation, family friendly, arts, sciences, manufacturing, easy highway access, coastal neighborhoods, new modernized port facilities, mining, fortune 500 companies and much much more.  

George Allen can help direct you to new home manufacturers that specialize is what is called "Community Series Homes" and has other knowledge and expertise for community owners.

Then I moved on to manufactured homes. 

I´m not familiar with any service that tells you the proportion of multi-families vs single families vs townhomes vs manufactured homes in a particular area - that just comes down to local knowledge.I´m based overseas so do most of my research remotely as well, but as @Michael Haynes alluded to above, you really need boots on the ground to be successful.
