Does anyone know when will the BTOs for November will be out?

Hi anon,
From the past few launches, I'm thinking mid-Nov onwards? Best to register for their alert service like Alvin mentioned and keep checking their page.
Even with a non-mature estate, it's all down to luck. But if the estate you're applying for is within 4km of your parents' flat, you'll get extra chances!
Or if you've previously applied for a non-mature estate and didn't get a ballot number, you'll also get an extra chance if you apply for a non-mature estate again this round.
Good luck with your application!

Use their alert service.

If you really need a place to stay, a non-matured estate would be your best bet.

Also can try for Open booking of flats, very little units available but you never know. If fast enough by the next week, you’ll have booked your flat.
