As a pure guess, if you form a single member LLC, your wife could still be liable as she would "own" 50% of your equity in the LLC.

Every time you form a corp, you have to pay the annual fees.

.$150 is never going to be enough to cover the incidental stuff that happens outside of your pro-forma expenses.

I am self employed and I was thinking about opening a solo 401k to roll over some money form a previous employer to invest in real estate rental.

There are three reasons, and ONLY three reasons to form a partnership:1 - Your partner(s) will/can do something you "can't" do....as in fill a void.2 - Your partner(s) will/can do something you "don't want to" do...if you don't want to do it, you won't do it well.3 - Your partner(s) will/can do something you "shouldn't" do....just because you can do something, doesn't mean you should.In this case, I don't see any answers to either "A" or "B"...yet.

Or how many of them simply put depreciation and equity predictions into the ROI pro forma.... 

You should definitely get an LLC if you are going to form a partnership.

And I’d bake-in that PM cost into your pro-forma.

Michael Lopez After reading J Scotts book, take a contractor, pay him his day in exchange that he teach you how to form a good SOW which can be understood by all contractor types.

Now you may form a company to conduct your real estate business.
