I have a challenging staircase design and swimming pool room. 

Overall, CA laws try to promote ADUs to help address the affordable housing shortage but local jurisdictions can make it challenging.

Which part of the process do you think is the most challenging?

Yeah, you have to assign a value to the house when purchased, which can be defended.....subtract that from the purchase price to determine the land costs and your cost basis for the .36 acres you’re selling is about 75% of that.  

Challenges?

If this is another owner, you are probably going to have to have some sort of legal agreement that allows them to put a renter in place on your IRAs behalf, and you'll need to have all the payments and paperwork come from your IRA so you don't blow it up.This is just another example of the challenges in investing with SDIRAs.

@Serena Kim I agree with what Charles said above - the other advice I'd add to this is the attorney - HIGHLY recommend Dugan Kelley - he has done all of our acquisitions and is incredible - especially when you have a challenging seller - he's great at keeping the deal moving forward.

Challenges?

Narrowing it down to #1 is challenging:1.)
