Banks will want you to show some reserves for unexpected repairs, evictions, ectI recommend you get all your stuff in order; pay stubs, 2 years taxs, hopefully solid credit score and some previously established credit, and create a brief outline on the property including income expense numbers, and see what different lenders offer.

Find a team to help you: real estate attorney to draw up contracts, tax accountant/cpa to help outline the implications of this type of deal.You don't really find those sellers.

What is more important, getting cash to start investing as you outline above, or keeping it as a rental.

Create a report that outlines in as much detail (these are good) as you can get and then add account statements, tax returns, etc.

At the very least write a letter to the seller outlining your offer and justification.And as mentioned in a different post by @Jay Hinrichs have a photocopy of a cashiers check for the offer amount.Keep in mind that when submitting an offer on a listed property that using the Listing Agent is always your best option.
