'He has the money and he has the flat'?
No he doesn't.
If you were able to arrange a free half hour of legal advice and get legal aid (as suggested previously), you would be able to get an occupation order - the police would make him leave. He would be prevented from coming back to the property at all.
This is because it's not HIS flat, or even YOURS. First and foremost, the law will consider your daughter's right to live in her home and have security. Who cares for her, you or your H? That's right - YOU. So you would stay with her, and he would be made to live elsewhere. Go and see a solicitor for a free half hour, and read up on this too.
Secondly - no, it's not his money! If you do divorce, the reality of this will hit him very hard! It's FAMILY money, and he would have to provide for his daughter - which would mean paying you maintenance. Yes, he may make this difficult... if he does, well, lots of people on here have managed through that scenario. I've not heard one of them say they'd rather still be in the abusive home. You already have a job, so you're on the first rung of the ladder towards providing for you and your daughter through (I hope) the long and happy future that lies around the corner for you both.
And as for fearing being without your daughter? Well, from what you've said he is a classic in this regard with his threats of 'taking' her. But your posts make it clear that he doesn't really want to be bothered with CARING for her. Getting up in the night, having his routine (Sundays spent reading - park? oh no, don't want to...) disrupted. It's overwhelmingly likely that he will want to see her, but not do the hard stuff like have her overnight, no matter WHAT he says. Your story shows that he is most certainly a very very poor father right now.
Because he is a bully and curently shouting the loudest here, you've been threatened into thinking that he has the power. He really, really doesn't. PLEASE go to WA. You most certainly are a victim of domestic violence, and so is your daughter. Phone the Met Police too and have a chat. WA will give you all the advice you've received here, in more detail, and like so many women before you you will realise that he is NOT in charge of this situation. I have a very good friend right now doing the same. Her nasty little bully of a husband is currently getting some of the biggest shocks of his life, and the look on the face of my friend as she really begins to realise that with the law and her friends behind her she can control her own life and make things better for her children is priceless.
Good luck with your first steps towards a happy, fulfilling future x
