When I'm preparing these letters/documents, I'm really learning as I go.

I am also requesting you provide documentation showing I am, and should be, the party responsible for paying for improvements made to the property I rent.

It doesn't quite remind me of 2004-2008 since the borrowers need to have a history of paying their bills on time and provide evidence of the capacity to repay the debt, for investment properties lenders are requiring anywhere rom 10-25% down depending on the loan amount and documentation. 

This is an area where members can share spreadsheets, forms, documents, pictures, and more.

What kind of documents would I need to cover both of our ends in any worst case scenario and where could I find some examples?

You should 100% be able to get all the documents you need from HERO.

- Properly document your rental income on a schedule E and report it to the IRS.Connect with an Investment Friendly Lender- Not all lenders are equal.

The only good news for you is that no one else is claiming ownership.

The majority of data is open source and we can get it by simply looking at Zillow, county websites or heaven forbid taking a trip down to the county clerk’s office and actually pulling the documents.

They will need to see all of the documents you've signed regarding the loan.
