Hi Peter, I would really like to know how to go about setting up a corporation in the US, what to do and what no to do?

MF complexes are better than 1to 4 unit houses because of the existing competition.Another thing you should consider is forming some type of corporation or a LLC depending on your financial worth and plans on what you are doing.  

Do you cater to the buyer or seller..or are you acting as principal?

At a minimum, it seems one should run a credit check, employment verification check (to verify their past is what they say it is), criminal background check, bankruptcy check, perhaps research previous LLCs or corporations the person has formed.

It’s a hybrid of a partnership and corporation.

Also, were they letters with hand-typed font or corporate looking?

Very few lenders truly cater to the borrower experience and the bigger picture, and don't understand the reciprocation of creating a raving fan from the borrower, realtor, attorney, or any other related party.

Then, the next question is what type of deals would you be excluded from even under a corporate entity?  

We cater to the investor from acquisition to the sale.

One of those thing to your fininacial well-being and that is to determine some type of corporation or a LLC.
