Are you having trouble making your payments and if so why are you looking to buy a second home?
You wont have any trouble with FHA if you lived in the condo for a while, FHA has this requirement because they do not want "Investors" to use their low interest rate low downpayment loans to purchase investment properties. The FHA loans are meant to provide housing for you to live in yourself, however if your situation changes and you need to rent it out or you choose to purchase another home and rent it out later. You should not run into any issues, to be sure ask your mortgage rep or attorney which you used for the purchase to be sure.
You are not going to get a mortgage with a 40% debt to income ratio and if someone offers you one, you will pay through the nose and still may not be able to actually get that loan funded. Don't you have any other expenses to live? Food, Cloths, Car, Insurance, etc.? You shouldn't be considering spreading your income so thin, I'd suggest speaking with a financial consultant for guidance.
