Do we have any legal recourse regarding claim to a builder lot and/or any case for damages?

In February my wife and I wanted to buy a lot and build a house in a Lennar community. We identified the lot we wanted to the Lennar salesman but it hadn't been "released" yet. That was supposed to happen at the beginning of March. As interest emerged on a the lots, the salesforce, including the sales manager got together and agreed that they would reserve lots, that when released, would be based on first right of refusal. We were told we had first right of refusal on the lot we wanted. Thus, we completely stopped our house search in addition to renting a house in that community for a year awaiting the completion of our house. The March release did not happen, nor the April or May. Nevertheless, throughout the spring we were assured by our salesperson not to worry, that when the lots were released that specific lot was ours (I have text messages from those promises). Two weeks ago we were notified that Lennar had changed to a bid process and we were no longer guaranteed the lot.
