I have just under five rental properties and I understand the legal benefits of creating an LLC (married to a lawyer).

I have a few questions- "We started an LLC" "We purchased a property" Who are the legal owners of the LLC? 

Namely, that if a tenant (in this case accompanied by a whole family) ends up stop paying rent and I would be on the hook for both covering the mortgage and dealing with open ended legal costs and time.

You can't legally deny a true service animal.

With a backup plan, and proper (extensive) legal docs, much of the risk can be mitigated.

@Emily ShinHouse hacking a multi-family property is an excellent way to start investing in real estate, especially in a market like Columbus, Ohio, which offers affordability and growth potential.

But the road crosses 3 other properties for which there is no legal access.  

The rates vary throughout the State because of the different millage rates and tax districts, but in Richland County for instance, the taxes essentially triple once it goes from legal resident to non legal residence. 

Tax and Legal ConsiderationsUnderstand the tax implications and legal responsibilities associated with rental income.

The primary risks at this point would be       1) to your lender, the risk of a margin call.       2) To you; underestimating the true cost of a project and cost overruns      3) To you; legal risk of securities regulations if you partner looses money.
