I have several projects going on in Massachusetts and want to be able to design my own floor plans and 3D rendered walk-through. 

I’m planning on building 4 townhouses (see the renderings below), and building them right next to BART.

That sets a base line from which to judge the value of the service rendered in light of the Act mentioned.

@Brian Klingbail I can't render an opinion without seeing and understanding all the facts and circumstances.

The rules that you cited seem to corroborate my thoughts: "(A) A non-lawyer shall not furnish to another for compensation, direct or indirect, advice or service under circumstances which require his use of legal knowledge or skill in the application of any law, federal, state or local, dealing with taxes, except:(2) A certified public accountant or a person duly enrolled may practice before the Internal Revenue Service, as those terms are defined by the then applicable federal regulations and the extent permitted therein.(4) A non-lawyer may render such advice or service incident to an engagement to provide products or services which he is otherwise authorized to provide, where such advice or service arises out of the providing of such other products or services and was not the principal purpose of the engagement."

The clerk of the county or municipal court in which such judgment is rendered shall transmit an authenticated copy of such dated judgment to the county recorder of the county in which the property is located.

In the state of Texas, the minimum bid is going to be the lesser of  the appraisal value or judgement rendered for unpaid taxes.

What are some of the common mistakes that can be made to render the LLC invalid?

Or, if your broker will pay your for services rendered over bringing in deals.

If you sell real estate before 12 years, you pay 25% capital gains, rendering any deal impossible.
