You will probably also need to submit IRS Form 4506T.The more documents you can get to the lender, as quickly as possible, the better your chances.

Part of me wants to document the goodwill I am expressing in appeasing these people.

Go on zillow and see how many condos there are,  Also check the HOA documents to see how much reserves they have for new roofs, common areas, how old is the pool, etc.  

Especially if their is mortgage insurance the loan servicer will need to demonstrate and document they did everything possible with workout options to get the loan performing again before going a short sale or foreclosure route otherwise mortgage insurance will try to deny the claim.Owners typically will want to milk as mentioned every free month they can get.

What documentation and data do you hold onto to share with the accountant? 

Yes, someone else said that so it can be recorded, yet it leads to yet another document that needs to be created and what might you put in the memorandum, and does anyone have one for Texas?

- If you know of a mutually binding agreements, either for a JV or for profit sharing, I'd appreciate you sending me the link or sending me the document directly.Any other advice or suggestions you can provide would be greatly appreciated.Thank you!

@Jake Walroth if it is a TAW, I would recommend a new documentation.

Go to Fileplace on this site and see some example applications and other documents. 5.

I would also like to start a blog documenting the entire process in gory detail.
