House Hacking Delimma

[Phillip Henderson]

Good evening BPers, 

I have run into a delimma while attempting to house hack. I found a duplex with one unit leased and the other unit empty. I put in my offer and got it accepted. While working out my loan and doing my due diligence, the seller filled the second unit. I was going to use an fha loan to aquire this property. What options do I have? 

Thank you for your time and advice,
