I've also found tenants from online classified ads, holding an open house, and from my own website. 

Maybe some document preparation for atty 150.

I am nervous and unsure as to how to approach it being that not only is this my first deal venture, but I also am not 100% sure how the seller finance process works legally and through documentation as opposed to a traditional home loan.

just reading online it seems like it should be a matter of months, not years. but i am not educated in the topic... perhaps it is very complicated!

If it is not something a consumer can do online that can usually help the business with a storefront.

The fourth lesson is documentation makes or breaks your investment.

If you use a bank they will have encrypted ways to send sensitive documents.

I document everything, it takes less than a couple minutes to type up how a real issue was addressed or if the soon-to-be former tenant was just messing with me I type it into a notice to cease/quit.I renovate on vacancy.

They have great customer service and their online banking is extremely convenient.

I was just under the impression that since the value of the property hinges on the NOI (being 5+ units), I would need some proven history to document the actual expenses.
