I have read that it is very difficult/near impossible to issue conventional mortgage at a 4.5-5% interest rate if you are incorporated, due to Fanny Mae & Freddie Mac restrictions. 

Would love to learn about them so I can see about incorporating into my life/routine as well. 

Also too long in this cocoon and I might get comfy arm chair investing.

It’s definately illegal in unincorporated Clark county (which somehow includes several small towns, I guess they aren’t incorporated.) and within 600’ of an existing Airbnb in Las Vegas.

To answer your question: you should consult with an incorporation attorney to determine if single vs multiple LLCs are right for you as far as mitigating risk or other issues.Congratulations and I wish you nothing but success, Spencer.

I've advised clients  with multi-families that if you show the bank that you are majority owner (articles of incorporation) they will likely acquiesce to the change. 

Find yourself a lawyer who specializes in corporate law ... a thorough operating agreement is a pretty boiler plate document.

They can easily jam the door with a chair or something for the night.

You will have no idea what clauses to put in and words to use in the initial filing and articles of incorporation to even start the process.

The reason I ask is it seems as though I would be double counting on-going expenses (insurance, taxes, and interest) if I also incorporate them into the initial investment calculation as well as in the NOI calculation.
