I plan on starting out next year with a small plug and play solution to have minimum risk.

I have heard of Royal Legal Solutions but have no connection or experience with them. 

I don't see any reason why this wouldn't be an acceptable solution.

Would an LLC be a viable solution?

Quote from @Joseph Chiofalo: Hi Kathryn, Thanks for sharing this info-  I believe we can be a solution for you and your clients. 

I contacted ALE solutions on Friday through their housing request form and just resubmitted with a longer term minimum based on what you stated here.

Working with the city to find a solution.

Even with a shared bathroom and living room, your place is likely much nicer than the average extend-stay motel, so if your rents are competitive, then you can likely serve this avatar.You may find that a 5/2 is an acceptable temporary housing solution for a family displaced after an insurable loss (fire, flood, etc.).

Because the gutters usually a better solution at much lower cost.

I am an experienced investor and unexpectely find myself managing a duplex myself and wondering if there is a small landlord (aka inexpensive) simple solution for marketing, background checks and lease creation that markets on zillow?
