Inheriting tenants on a primary residence

[Jacob Northfield]

Hi folks,

I am purchasing a duplex which is currently occupied, but since I am using an FHA loan I have asked the seller to have one of the apartments vacant so I can use it as my primary residence. By law I am required to give the tenant 3 months notice to vacate, but I close this month. If the tenant stays for the three months while I finish out the lease on my apartment will I be committing mortgage fraud? Do I need to let my mortgage company know about the situation and will that affect my loan? If there are resources out there explaining this process please let me know because I haven't been able to find too much out there about inheriting tenants and what to do after closing. Thanks!
