Upstairs tenants admit they aren’t “parties,” but sounds like they don’t want any visitors at all at the house.There are shared spaces- front and rear entries and laundry facilities in the basement.

However, Person B agrees to manage the property until ~year 3, when person A + B jointly refinance.Additionally person A + B will enter into an operating agreement which binds both parties to these conditions and offers 50/50 equity in property.How do we structure this legally while minimizing the liability, in absence of a LLC.Side question:Are there different lending rates between a LLC and an individual?

Partying like it's 2006, with margins that are lawful for mortgage bankers, but that would be illegal for mortgage brokers (guess who has the better lobbyists?
