Hey there....I'm not an agent, but a fellow home buyer here in SJ. I can tell you that my husband and I looked at both of those developments. It was interesting because before we looked, Celadon was looking pretty good to me, until we saw the layouts. We are young, very early 30's and no kids yet, but within the next 2-3 years, yes.The only layout at Celadon that we considered had one room on each floor. I don't know your situation, but with little kids/babies, that's not ideal and was a deal breaker with us. I actually have Harmony's floor plans sitting right here in a huge stack beside me! We did not like Harmony because the models felt small to us when it came to the actual living room area. The major turnoffs for both was the "lottery" combined with floor plan. We also just looked at the Rows at Coyote Creek yesterday! It is in a very commercial area in Milpitas, but like the guy told us...on the weekends, we might as well be out in the country. There was no one around. They do not do a lottery system...it's first come, first served. The only con about it for us was no yard and they don't all come with the huge balconies you see on a couple of the models. The only thing that I did think about was how would it be with all the traffic on weekdays? Also, the hard part was, no one could give us a solid price, as the pricing they had was for "previous releases" and that the price will go up with each release. I can tell you for Harmony, they are saying the residence 2 and 3 floor plans are going to be over $600-650K and you can actually find a house in Milpitas for around that same price that will actually have a yard. To be honest, these places were telling us they had waiting lists of like 1200+ people and with the lottery system, good luck getting a house! Celadon is a better value, but then, your AC unit is RIGHT on your front porch. Does that matter to you when you have visitors? It bothered us. BUT, their floor plans are smaller than Harmony and depending on how much they raise their prices for the next release, Harmony could be the better value. But if I had to pick one, I'd go with either Harmony or The Rows. The guy at the Rows told us yesterday his wait list is only about 700 people...for now! Also, it's an out of the way location, so it's quieter, in general. You might want to look into it. My husband and I actually decided we no longer want a townhome/condo because we can get a single fam home for under $100K more.
