This appears to have been amended.

OWNER and BROKER further agree that enforcement of this provision is appropriate through a temporary restraining order and/or injunctions and permanent injunctions, notwithstanding any rights under the First Amendment to the United States and/or Texas Constitutions or other codified statute, regulation, or code and that any party who prevails on enforcement of this provision, whether for monetary damages or injunctive relief is entitled to recover attorney fees against the other.

I like that idea, but would probably have to amend the lease. 

Someone suggested amending the tax return, but one of the lenders said they would look at both returns and it could be an issue still.

Selling retail to a Fannie Mae homebuyer, no, not unless you can amend the contract to be between the seller and the buyer. :)

We want our tenant to sign an amendment that the lease is with him and the llc and we are just members of the llc.

Have you read about the original intent of the amendment from some of the authors?

You need to get an ATR "authorization to release" letter signed by the seller where you are allowed to negotiate the lien on behalf of the seller.The lien holder might release the lien for a nominal amount. 37,000 for 3,700 BUT they will retain the right to pursue the borrower for the balance in the future.They will not release the whole lien amount for that and let the borrower off scott free unless they are not an astute lien holder.You need to find out WHAT amount the lien holder will settle for to release interest and then go back to the buyer and see if they will up the purchase price some with an amendment to purchase agreement.No legal advice.
