@Jean PierreSome states impose transfer taxes on both an asset purchase or a LLC membership interest purchase.

Seems unnecessary to give away most of the profit to an investor if all they're doing is the financing?

Doing anything else creates unnecessary complexity.

Sure, it might convince them to sign a shared-driveway agreement, but it could also stir up unnecessary animosity. 

It is basically a month-to-month agreement and surely can cause unnecessary confusion with legal docs. 

But, I think sometimes these things can be over-thought and just give attorneys unnecessary business. 

Here in Chicago air conditioning is more or less unnecessary in the B and C class areas as the summers just aren't that hot.

Maybe you could advertise in a way that allows people to contact you when they want to, rather than impose yourself via their mail and telephone. 

You don’t want any unnecessary stuff going into it.

I felt about 80% of the claims I worked on were created in the insured transaction and the problem was either known by or should have been known by the agent, resulting in an unnecessary concern by the Insured whether they have clear ownership of the property and delay in their sale or refinance of the property.
