Was the condo you are renting out your current primary residence? If it is, then it is a "primary residence converted to a rental property", and in order to use rental income in that situation you will need to either have 25% equity or be relocating to a new area not within commuting distance.
If it was your primary residence, then after you have reported the rental income on your tax returns then it can be used as rental income without having to have 25% equity or moving to a new area not within commuting distance - so that situation wouldn't apply until you have filed your 2011 tax returns in a month or two.
If this was another property you owned, and it was not your primary residence, and you just decided to start renting it out, then FHA just would require you to have a rental agreement and some lenders may even want to see you've actually received rent (cancelled rent checks from your tenant, etc.). FHA does not have a requirement for you to have rented a home out for 2 years in order for the rental income to count, if you run into a loan officer who says it does (and it sounds like you did) then they are telling you what is called an "overlay guideline", which is a guideline that their individual bank/mortgage lender imposes that other lenders do not.
I would go back to the first loan officer and ask them to make absolutely sure they can use the rental income, as some loan officers may say they can use it but are unaware their own company has overlay guidelines. The loan officer should either forward you an email they received from an underwriting confirming it's OK, or provide you the section of their underwriting guidelines which says it's OK.
