Pro's of both are they are waterproof, scratch resistant and easy to install.  

They're also familiar with different contractors who can give you estimates on delivery of the building, site preparation, installing the building, hooking up utilities, etc.

You will only use 10% of the course though, they don't really teach you how to install drywall but they could teach you how to do RFIs COs and how contracts work.

This can save you A LOT in the short and long term, especially for big ticket items like flooring, tiling, paint, kitchens/bathrooms, etc.2.

You want no liability for something that might happen from the installation 

I paid for and did labor to tear down a rotting shed, install an interior stairway handrail, and cleaned up around a leaking chimney flue cap.

From there solar panels and a Tesla Powerwall can be installed.

Our clients will install a hot tub with attractive lighting and so forth.Another consideration is the leasing contract.

They can be on a ground level foundation, or on pilons or walls....I've seen some renovated with ceramic tile, another has a parquet hardwood floor.Manufactured homes are good for rentals, such as in a park.

I've had 5 companies come to give a bid on installing steel security doors and bars on my nice rental in a nice area.
