Rents too low for FHA?

[Eli Wheeler]

So, I finally found the beautiful four-unit in an amazing area with an amazing School and a garage. Everything I've been looking for for my first owner-occupied. But of course there's a catch, the rents are a little more than half the market rate. My lender tells me that for it to qualify it has to pay for my Piti payments with current gross rent minus 25% for vacancy and maintenance. Gross rent could easily be pushed to $4,500 but right now it's only 2530. It's a very hot property and start showing Monday so I don't have much time to figure it out. Has anyone run into this problem and overcome it? Ideas? Thanks for reading!
