The answer is the same. Since you are using an FHA loan I also assume you are a first time homebuyer. You need to speak to your buyers agent. I hope you are not trying to use the seller's agent. As a first time home buyer with an FHA loan you must have your own agent. Your agent should have some attorney contacts that can look at your lease and help you through this. Seller's can offer you the moon but, it is not up to them what they can actually do and deliver on. You lease is the key and it needs to be previewed by an attorney. Then you can get an educated view of where you stand.
If you can find someone to rent your apartment then the management may let you out of your lease.
Hope this helps,
