Validating Investment Property Income

[Jason Young]

I'm considering purchasing a 5 family rental and am curious what I can expect from the current landlord in terms of documented performance of the property.  The property looks good "on paper", but I would like to see a year (or longer) worth of documentation on the actual performance.  Understand that this is entirely based on how organized the landlord has been with their record keeping, but curious what experience others have while performing due diligence.
