My strategy is less than a page and it contains mostly bullet points (not a lot of text). 

I hope someone in Sub2 community who financed purchases of the homes they sold could share in few bullet points how they accomplished it, while staying compliant with Dodd Frank and Safe Acts.    

There is no silver bullet.

On this one I had to but the bullet because they had converted a bedroom to a bathroom at some point and I really wanted to restore that bedroom so invoked claim the higher rent.  

Nothing you mention is "ordinary" and you should charge for all of it. dodged a bullet there thats a very good price take it from the security deposit and call yourself lucky. 

If I just bit the bullet at $1,000 dollars and gave it back to them so they could leave I would have saved $19,000 and 6 months of time.

Here's the silver bullet, though, that most people can't fully grasp.

Additionally, not all transaction types support Locations, meaning you'll have to create journal entries to correct them—requiring a solid understanding of debits and credits, which can be time-consuming and error-prone.Instead, I recommend biting the bullet and upgrading to QuickBooks Online Plus for each entity.

The bullet in the response that is standing out to me is:"(7) The accessory dwelling shall not be a short-term residential rental, as defined by City Code section 3-2-152(a)(2), for a period exceeding 120 days per calendar year."

Follow up with an email to the agent and bullet point your case, which increases the chance that the owner will actually hear them7.)
