Not everyone is currently an early retiree nor do they have experience in the real estate field.  

There are a lot of military and retirees on the site.

Unless you are in an urban core city most of the outlining suburban to rural towns in rust belts states are dying off.The reason is very simple as the population ages with over 25 million retirees they are flocking to warm-belt states.

Tens of millions of retirees are flocking to warmer climates.

I believe that this could generate a whole new class of reliable renter in the warmer climate that Florida offers (in addition to its already many retiree-centric policies and amenities).For Brevard, I have a personal interest.

Retirees?

Agreed, buyers are most often looking for the classic 3/2 although here in Florida with the snowbird factor and empty nesters/retirees there is probably a larger market to sell 2 bedroom homes than other places

Good blue collar working neighborhoods, wealthy coastal areas, and retirees.

I met a retiree who told me she spent $55,000 on his program and it had been a year and she hadn't received her first deal.  

On a price per Sq Ft basis these homes will "appear" expensive as they are certain costs that all homes pay, IE impact fees, ETC ETCI think this product (if marketed right) would benefit the lower end of the blue collar retiree spectrum, as they are essentially the size of a smaller mobile home.I also think millennials would love this product.
