Update :
We got the house!
We were (are) extremely busy with reading the contract, reviewing upgrades and making selection; we only have a couple of days to go.
First of all, my thanks go to all the TI community members who sent me a lot of comments, advice and PMs.
Here goes our story, last week I got a call from Irvine company, the person on the phone (couple of people here asked me to not include any name) told me that bcz the other party could not wire the money in timely manner they decided to give the house to us. Whatever the reason was I did not ask about the priority list and ... as at that point we didn't care. But the person who spoke to me about the situation, told me they (Irvine company) prefer to sell the houses to the people that give a sense of community to the whole neighborhood and the problem with our case was that there were two agents were working with two different clients on the same lot at the same time. Anyways, long story short, I don't really know if it was due to my calls, my post here or just luck, but we have gotten what we wanted !
