Yeah, there is NO WAY she will get on a lease...tbh even if she was 18 I would doubt it with no work and no rental history. DF and I live in a share house currently (I'm 20 in a few days, DF is 20 in Dec). We lived in a flat together from 18, and it was a major pain in the bum finding somewhere that would take two kids with no rental history. Luckily DF and I both had solid working histories and were partnered, which I think helped.

Sharing a house is a good experience. It is probably suited to younger, less attached and less grounded people like your DSD rather than DF and I, but we need to save some money atm so it's a good option. We still found the market difficult, even with sharing. In fact, a lot of the time the price for a room in a share house was similar to a cheap 1 bedroom flat Does your DSD understand how expensive and huge a responsibility it is moving out? Another thing to consider money wise (you may have already) is going to Centrelink and getting an Unreasonable To Live At Home form. It's pretty much how it sounds, you fill it in saying why it is no longer feasable your DSD live with you anymore, she fills in the same, as does a third party. This will allow her to recieve the indipendant rate from Centrelink. For example, DF moved into a student shelter to escape his stepfather at 15. From 15 to now he recieved from Clink $370 pf, a huge amount compared to my $140 pf. We are both students etc, only difference is he moved out and separated from his mother whereas I stayed at home and was means tested. So that would be something to consider finacially if she is adamant on moving out and does not have a job.
