Is that the appropriate document I should have him sign?

While I pay her rent there is no official document or lease.  

Lastly, like any other close, make sure your financial documents are in order... you'll need copies of taxes, bank account history, investments, etc. gathering all of that information can ne a pain if you aren't organized.

What type of documents could I ask for?

Each regional VA office requires different documents, however these are the BASIC documents required for VA Condo approval. 

We were asked by several past clients to help provide them with documentation to support their request.Look at the tax assessor's office website.

The only downside is that ridiculously long SDIRA name that has to go on all of the documents, but I am already over it....LOL!

After providing all my documentation, I have been advised that due to my short Canadian credit history (I'm Irish) currently I would be eligible for an A-Alt rate of approx 4.99%, with potentially reaching A rated credit in 12 months. 

Non performing notes have so many risks and little costs that add up to a lot of money, servicing, insurance, taxes, document storage, recording.

Here is link to an official government document on this issue: http://www.sos.state.tx.us/corp/forms/304_boc.pdfFor what it's worth, many states require registration, if not all.
