Question regarding FHA and residency requirement

[Nicole Heasley Beitenman]

I got into a discussion with my father recently about FHA loans and the requirement that you live in the home the majority of the year. We had a bit of a debate about whether or not the bank could do anything if they found out you were not living in the home as a primary resident. Would they be able to take the house away from you? How would they even know whether or not you were using it as your primary residence?
