If you can prove that the developer lied *at the time* he made that representation to you, then they may be fraud and you may be able to rescind or void the sale (return house, get money back), possibly with some adjustments for the value of having lived there a year and/or for the current condition of home. You'd have to sue the developer and prove the fraud--the lie knowingly made at the time--in court.If the developer did not lie at the time, but conditions or plans changed afterword, however--for example, different management came in, the market changed, the developer was offered financing for a multi-family units, etc.--then it was not most likely not fraud and you would likely have no recourse; the law accepts that conditions and plans do change after the fact.
