Costello, the Third Circuit and Seventh Circuit Courts found that cohabitation without more is not enough to constitute harboring.

Check co-habitation laws in your state.

You will probably be able to rent it to a large family or a group who are already cohabiting, effectively using it as a duplex but signing a single lease. 

I personally don't concern myself with restricting roommates because married couples break up almost as often as any other type of cohabitation situation.

Just because one cohabitates with another human being doesn't make it a "successful relationship" (i.e., couples staying together for decades because of fear of the unknown, public image, children, other people's opinion, etc., etc.).

But I'm actually not sure if your GF and You would count as one or two unrelated people (I'm a little shaky on the specific of what related technically means in Durham, I don't know if the town lawyers have weighed in on non-related cohabiting couples).I wouldn't worry too much about a family in the 3BD for 2200.

Like everyone else, we're expecting a correction in the market and our home value; but in the meantime, we opened a HELOC and are using that equity for investmentWe live in one of the most expensive markets of the country (San Francisco bay area) - Rents in the city are north of $4,000 for 1 bedrooms in nice neighborhoods (which is why so many folks have to co-habitate). 

After that is done if all is well we set a time in the next day or two to have Johnny sign the lease and at that point y’all are cohabitants and roommates.

I feel it puts a landlord in a complicated situation especially when cohabiting with multiple families and it needs to be handled tactfully .
