househacking w/ adu.

[Gerardo Vasquez]

current harris county resident. if you purchase a duplex with an fha loan or conventional loan and you place a tiny house as an adu on property and rent out the duplex. Would that be considered still your primary residence? Can it be on wheels or does it have to be placed in the foundation? Better just to do an fha 203k rehab loan and add an adu? Will do my due diligence on zoning regulations (houston,tx) and run the numbers to see it actually makes sense. Just an idea i been mulling over. all responses welcome.
