Check out Mark Ferguson's blog I googled the question since i was also curios to the specifics.
Couple things can happen if you as an investor who plans on not occupying the property put in a bid as an owner occupant, they are kind of serious:
All owner occupants sign an Owner Occupancy Certification - certifying that you will be living there - for at least a year. If you happen to falsify this you could:
1.Pay fines of up to $250,000 and some jail time...and
2. The agent/company who helped you make the bid can lose their NAID# and ability to make any HUD bids for any customer in the future. So, your agent probably won't let you do that once they find out that is your goal.
Also, the listing agents are also on the lookout for investors trying to do this.
Oh yeah, and other investors, like the one you just bought a house next to, are also looking at that property, and when they find out you got one and are not living in it, since they were waiting for the "extended period" may not have an issue with turning you in to HUD.
Mark Ferguson's blog has more info on this. In short, you don't want to do it.
