Hi gollan,
My heart goes out to you.
You know the most important thing is your daughters safety. Thank God she has parents like you that have helped her escape from this man before he did any more damage to her, than he already has.
As far as the home and your gift of equity - a good lawyer should be able to help you out on that one, like Joe said. One thing to keep in mind - they have only owned the home for 6 months. Unless they bought below market value - it is doubtful that equity has accured 15% in that amount of time, without some home improvements. Though in some states that would be the norm for a 12 month period. I don't know what state you live in so I can't really say. There are states out there seeing a 20% increase per year. I think Maryland leads the race on that one.
You said he can't get a loan on his own. Do you know if he is making the payments? The sooner you can get a lawyer to draw up some papers addressing the issue of this, the better. There at least needs to be something in writing stating he has to make the payments on time as long as he is living in the house - or forfeit his rights. Her good credit standing is on the line if he doesn't. If he wants to drag the sale of the house out, at least you will have that much.
Also .... I know that some banks will make you go off the sale price if the loan does not have 12 months seasoning, on a refinance. So, the equity might be hard to draw out on a straight refi. Can be done though. Just creatively, is all.
Alot of issues here.
Like Joe said.......get a lawer ASAP. If the one you called is too busy.....find one that isn't. There's alot on the line.
Might be a good idea to seek some counseling for your daugher. Sounds like he put her through some pretty bad things.
If you need some help on that , let me know what state you are in and I will pm you with some people that can try to help her.
Best of luck.
