Refinance Loan Time to close?

I am trying to refinance on my condo with an fha loan. I have a 715 credit score. I was suppose to close by early april. They have all needed documentation and they keep telling me their waiting for the underwriter to make an exeption cause my income ratio is 2% lower than what they usually accept. I own two other properties which i took a loss on last year because i was rehabbing them which is the reason my income ratio is 2% below what they accept. Are they going to deny my loan or would they already have done so? I make 60k a year. The loan on my condo is going to be 138k. Of the 2 other homes i own one is completly paid off and the other one i owe 40k. I actually make a profit renting these homes but had to take a loss last year because of all the rehabb work i had to do. Why is lending tree giving me such a hard time and why are they so slow? Like i said i have a 715 credit score and have never been late on a morgage payment. Do you think underwriter will make an exeption in my case?
