Sorry it took me so long to reply, I was busy jacking off then I decided to play "football" with paper clips down the front of my assistants blouse.
You are asking one question but there is not one answer I am sorry to say.
Regarding your credit score: assuming you were not listed as a borrower or co-borrower on the house note, then your credit score should be fine. Don't assume you weren't if your Dad had bad credit. Good people forged a lot of documents back in the boom days.
House: don't assume the house will immediately go into foreclosure. Also, don't assume you don't have any obligations at this point. You can be sued personally for a breach of fiduciary duty by any beneficiaries of the trust if you wrongfully allow it to go into foreclosure. You don't want girlfriend's lawyer calling you up 5 years from now claiming you failed to act on a bona fide offer to sell or some other such bs and cheated her out of the money. Yes, I know the trust doesn't mention her, but you still need to cover yourself.
Tenant: get them out now. It doesn't take long, you can do it yourself for non-payment and there is too much risk of personal injury fraud etc. You don't want a junk lawsuit against you personally claiming they put you on notice about something and you failed to act.
Bottom Line: your patience and money might be short, but there are still some risks here that can expose you to liability unless you act carefully. Visit
