Hi @Libby Tucker I just went through the process of buying a duplex in the Bronx. Where in the Bronx is this property? I'm on 167th street just off of Webster Ave.
My experience with FHA was a fairly smooth one. As mentioned above, all of my income had to be sourced. Even my friend who paid me back $1k for a flight I bought for her. They asked for her bank statement. I had to ask my father for a gift fund towards my down payment and he had to sign a document stating that it was a gift. I tried to get creative and take out cash advances from my credit cards, but my mortgage broker advised against that saying that most likely would not fly. Luckily I was able to get some help from my dad so I did not have to go down that road.
I have a great mortgage broker that may be able to offer you another opinion. The one thing I can think of that may help is getting somebody to own the property with you that has the money for the down payment. I guess in that case, this person would sign a gift letter, but you both would be on the title. I would certainly double check this, but may be a way for you to get around this.
Please keep us updated on this deal.
