Is al jalil garden a legitimate housing scheme?

Gentlemen, is al jalil garden a valid housing scheme? Since its very cheap and i am looking in to long run investment, please advise if

1) its a valid scheme?
2) i should buy plot and hold it for long run investment?
3) any other better housing scheme with almost same pricing range?
