My first stop will be certainly my (real estate focused) lawyer, HOWEVER - if any of you get together to discuss this (or anything else for that matter)- I'm happy to buy the second round ;O)

Mat is also an attorney and specializes in self-directed retirement accounts and entity setup.They're both partners in KKOS Lawyers.

There is no by-right exception to this, but if all your neighbors have smaller rear yards, you can appeal for a variance and it usually goes through (but I'm not a zoning lawyer so don't take my word for it). 

Any and all suggestions (to include other team members such as lawyers, accountants, mortgage brokers, and property managers) would be greatly appreciated.

Another idea would be to network w/ lawyers who handle those cases.  

Make sure your primary Team members that are local and are experienced in what you and what you expect.The primary Team members are Attornies/lawyers, real estate Agents/Brokers, CPA's (or knowledgable accounts), Inspectors with a license, General Contractors, Property Managers, and Handymen.  

The mortgage industry isn't spending on average $8,000 per loan to ensure CFPB/Dodd-Frank compliance for no reason; I suggest hiring a lawyer at least for your first loan of a certain type and certain occupancy intent. 

If you think it's going to be ugly, it's not too expensive to talk to a lawyer for an hour and get a clear picture of which steps you should take.  

You ask lawyers about law, and you ask realtors how to fill in pre-printed contracts.My $0.02 ...

also, besides the separate bank accounts...do not link them or transfer between them.Keep them truly separate, otherwise a lawyer will be able to "pierce the corporate veil".
