More states = more work.Sometimes syndicates may file a "composite return" for non-resident shareholders. 

Electing S-Corp status would allow you to add your parents as shareholders, where they could “invest” in the corporation.

This structure allows you to form a corporation and make your retirement plan a shareholder.  

If the business is profitable, you can also issue dividends tax-sheltered to the retirement plan shareholder and make new deferred contributions into the plan.It is a very powerful tool, but considerably beyond something that makes sense with $13K.  

One is to list like crazy and make it up on volume and the other is to be more selective on transactions so you make bigger pops of money with less time outlay.The big commercial sellers are about list for less as the REIT's and other funds want to drive value to partners/shareholders.   

Then, when the cash or other assets are distributed to the shareholders as dividends, it is taxed again at the shareholder level.In an S-Corp, it is possible to maintain the nature of the income and pass it through to the shareholders such that capital gains flow through as capital gains, etc.

You are the only shareholder.

But my next question is, when building business credit for an llc or s corp. will the place I get a business card take into account all of the shareholders personal credit or the business itself? 

That is to say that the shareholders are taxed on payroll and the corporation is taxed on earnings.Most real estate entities are formed as LLCs or S-Corps for that reason.  

I do like the idea of making my parents shareholders in my company if I can.
