Converting portable classrooms to homes?

I have come across some portable classrooms. These are essentially DW mobile homes 28x 54 for $17900. 4 large open rooms. No bathrooms. Optional heater $800. They are nearby. Condition appears very good to excellent. Would it make sense to convert these to homes? Anyone ever try this? What’s it cost to put a bathroom in a mobile home?

Well the bathroom would be $1500-2000 not including labor. But that is just the beginning. In the great white north the heater won’t cut it. So first thing you need to do is install a furnace. This involves cutting almost the whole underbelly/insulation away, adding a chimney pipe, etc. Add A water heater, windows, plumbing, walls, electric outlets, a kitchen, appliances, washer dryer fixtures, direct wired smoke & Co detectors, floor coverings, etc. I will take on just about anything but I think there are way better ways to obtain a DW home.
