Here is a good thread I started last week that talks about this and other topics in-depth: https://www.biggerpockets.com/forums/87/topics/80870

Feel free to text me if you want to discuss more in depth. 

Here is a pretty in-depth article on how to fill out IRS Schedule E:https://www.therealestatecpa.com/2016/05/22/ultima...

I may be willing to provide more in depth data about the property for those interested in helping.

I did talk with David briefly a few days ago just to get some initial information, and I am looking forward to getting much more in-depth in a few months when we are closer to making a move to getting some significant capital to hopefully begin the process. 

Also feel free to private message me with a phone number if you would like some in depth knowledge of the area.

I don't know much about the standard terms or down payment if any on a seller finance so I will have to research that in depth.
