It's a transaction.

@Joyce Martin the process starts by contacting APS or SRP to speak to their construction department.

Look up your state laws, or better yet call the police department.

Lizards too, but they're cute and not nearly as heavy in the gross out department as "Palmetto Bugs." 

Does anyone have any experience with banks in the Huntsville area that handle these transactions?

I believe FSBOs are great for better deals when the transaction is direct between seller and buyer.

Keep it up and adjust your systems to get better and better with each transaction!  

They'll simply have to sign a corporate resolution before close (signed by all members) stating that they approve of this particular transaction and all agree to give "____" signing authority on behalf of the entity.Pretty basic stuff.

It appears that you have an agent who is not experience with HUD transactions. 

Unless you invest via an LLC owned by the IRA, you will not have checkbook control over the funds which means you need to run transactions (e.g. income, expenses, etc.) through the trust company who will need time to process the transactions and generally charge fees for each transaction.
