You will need to hire an attorney to foreclose the property. You cannot get the property "repossessed" with going through the foreclosure process, assuming you gave title to the buyer and took back a note and deed of trust as collateral. Try offering the buyer "cash for keys", which means doing a deed in LIEU of foreclosure. Sometimes cheaper and easier. You'll likely need an attorney to draw that up as well.
An IRA has a designated beneficiary or beneficiaries, which already passes their account to your heirs. If that is your reason for using a living trust, its not really necessary. If you name the beneficiary as your living trust, then you may be able to control things better through the instructions in the trust, but there are different tax consequences for doing it this way, which you should speak with your CPA about.
He's trying to avoid having to give you a 1099, but what most people don't realize is that having an LLC does NOT absolve him of that liability. It's only if you are a CORPORATION that he does not have to 1099 you.
You mean "quit claim" deed. Only the owner (your mom) can transfer ownership because she must sign the deed. It's possible your sister prepared the deed and stuck it under her nose for signature, which sounds like the case. If so, you should immediately hire an attorney to challenge the transaction. If your mother is incompetent or was lied to when (if) she signed the deed, you need to take action NOW before your Mom is gone and there's no proof. If your mom voluntarily signed the deed and...
You can't name the LLC unless the LLC is at fault or she was working on behalf of the LLC when she committed the wrongdoing.
There's a law called "fraudulent conveyances" that allows you set aside any transfers that were made to the LLC to avoid paying creditors.
The standard Colorado Real Estate Commission contract requires first that you go to mediation. So your first step is to demand mediation. If that doesn't resolve it you can sue, but you will have to file in District Court, which isn't like small claims - lots of rules that will require an attorney. As a matter of strategy, get the seller to admit in writing why he won't close (bait him in an email). That way, you can use it against him later.
A lender does not have to give you a loan modification, you might try either a forbearance agreement, a Chapter 13 Bankruptcy or a short sale. In short, don't bother talking with an attorney just about the modification, but rather all other legal options you have for your situation. Good luck!
I am not sure why you would WANT to assume the loan, be personally liable for it, and have it report on your credit? Leave it in his name, and make it his primary responsibility. You can still deduct the mortgage interest if you own the house and make the payments, even though your name is not on the mortgage loan.
I don't see anything wrong the landlord did as far as YOUR rights, except possibly the security deposit. Demand it back in writing, and if he refuses, follow the procedures to get it back in small claims court. http://www.tenant.net/Other_Areas/Colorado/crs/103.html
If his emails are over the line threatening and persistent, it may be illegal harassment, which could get him into trouble if you complain to the Police. But it sounds like he's just a nutty old man, so get your deposit back and...
