I purchased my first SFH (3 bed, 2 bath) and currently have a tenant paying $850. 

I did my own review on bigger pockets.

I intend to get a single family residence, add an ADU, live myself in the residence and rent out the ADU as a studio apartment long term.I have checked my city's ADU laws and long term renting is permitted.Question : can I obtain the REP status while maintaining the ADU while it is in my primary residence?

Alternatively, if anyone has a good deal analyzer spreadsheet for seller financing options or the sub-to strategy, I would be interested in seeing those to incorporate with my existing analysis spreadsheet. 

I had already done this once before, entirely on my own dime, so I have the entire process down from beginning to the end.

I have done my research on setting up the proper entity structure in the US and Canada but I really confused about all the options available LP, LLP, C-corp, S-corp.

I ride bikes in my neighborhood and bought two houses in a similar way from tired landlords. 

I regret not hiring a GC as I acted as my own.

Jack and Jill homeowners have to pay off their mortgage and buy again, so aren't good SF candidates.All of my SF buys have been from tired landlords that owned free and clear.

(wisconsin)How can I best position myself in this deal where the lender is comfortable and we have a solid prefab, but also workable to where I can keep my sale price competitive and build costs down.This lot is within spitting distance of the lake.
