Understood that you can't really trust or believe what he says. My suggestion would be to do the following, in this order (sounds like maybe you've done some of this, so ignore what is repetitive):
1. Ask him point blank if he is using you and your credit history to help him buy this property (doesn't matter if he's telling the truth or not, you'll find out soon enough).
2. Ask him who the realtor and/or person he's buying this property from is/are, and ask for their contact information.
3. Ask him through whom or through what bank he's financing this purchase, and the contact information for it as well.
If he stonewalls on any of it, no problem, the matter is settled and he knows what he can do with his quit claim. If he gives you the info, then go investigate further, straight from the horses mouth. You might also want to look at the appraisal for the property - there must be one somewhere.
Of course, there's option 2, which is much more simple. Tell him to go jump in the lake, and forget about the whole thing.
Oh and just to be on the safe side you may want to contact the 3 credit bureaus (equifax, transunion, experian) and tell them to notify you any time your credit is checked. I believe that this service is of no charge to you. That way nothing can happen involving your credit without you knowing about it.
Hope you are feeling better, you sound like it at least a little...
