USDA Direct loan and airbnb or rent-by-the room strategy?

[Ellie Narie]

Does anyone know much about USDA Direct loans? Let's say I have a low enough income to qualify, and want to use it for construction. Here are some questions: 

1. I know that I can't build an "official" multi family home. However, what is defined as multi family according to USDA? If I just build a house that sort of looks like it could be multi family, such as, a house that is split into two, but doesn't have an additional range (still has an additional fridge and sink), would USDA be okay with this? For example, think of a "mirror-like" duplex, but remove the range from the one of the "kitchens" (still have a fridge and sink in both "kitchens"), and add a door that connects the two units, that way you can say that it's still a part of your house. But still have two entrances. Would USDA allow such a house? If not, what are some suggestions on how to make the house USDA-friendly, while still sort of separating it? 

2. Does USDA Direct allow you to rent rooms in your house? What about airbnbing the rooms in your house? Of course, you will still occupy your house.
