In all seriousness I think you have 2 options.
1. You ask her to do it and she loves you for it.
2. After a couple of months and her struggling to find a place, she asks if she can move in with you. Then you have to say yes or no. If you say yes, well done, you could have said yes earlier and enjoyed what I mentioned previously. If you say no, well there goes the relationship cause it will still be early days and she'll always slightly resent you for it.
