If you purchased the home utilizing an FHA program that requires you to occupy the home as your principle residence and did so with no intention of doing so, you had better find a resolution quickly. However, It sounds as if you may be too late to do so. I would contact HUD to resolve this issue immediately as you very well could be prosecuted for mortgage fraud which is a very serious issue (Federal Crime). Do not, under any circumstances, avoid the issue or, lie to investigators. If they have notified you that they are aware of this issue you had better be in constant contact with them with regard to this and cooperate completely with them. HUD, in conjunction with FBI investigators are pursuing mortgage fraud participants with much zeal. Good luck to you.
