From what I know, it’s a great neighborhood. Nice people, a big mix of Litvish/Sephardim/Chassidim (new area with lots of Belzer chassidim recently opened up for people to move in). Many Americans. Lots of apartments being built.
I know that people had complained that it was not close to Yerushalayim (for sure not as close at the sellers of the neighborhood would want you to believe), but in the last several months they have new transportation to the neighborhood with many new buses, even direct ones, back and forth to Yerushalayim, and the best thing is that you don’t have to pay more to get there anymore (before the Light Rail Train started operating it was a higher fare).
The prices of the apartments are going up all the time, but they are still probably the lowest around for an area that really is just outside of Yerushalayim. I’ve heard of apartments not yet finished being built going for 1.2 mil sh”ch for 4 rooms and 1.4 for 5 rooms. Those prices are up 50% from the original buyers in the neighborhood. The prices for finished apartments are probably 200,000 sh”ch more than the above prices, respectively. Rents are also lower than Yerushalayim.
Like I said, you can get my contact info from the mods if you want more info. BTW – I don’t think that “Ramat GZ”Ch” is another one, just an extension of what is already there with much fancier apartments/houses planned for building.
