I found a good website showcasing how to calculate value for larger real estate deals.

You get their best build cause it's a show case for them. 

Yeah, in OR you can't make a contract chained to a listing like that, but they do have ways around that like a "termination fee" which will get credited back if you use them to list.I'd also ask if they can do a summary on income and expenses and trends - Like is the avg rent up the past two years, what's happening with water costs, etc in graphical (ex-eng, sorry) format.Other item happening more is what happens to your data? 

They will showcase the most iconic architecture that is so unique to the time and place, their means and methods can never again be replicated. 

This will normally get you the Graphical Information System which is mapping software used by government bodies.

This is Not a horders situation, the Antiques are very nicely presented and many of the items are already in showcases. 

As you build up the audience over the next couple months you could showcase local businesses in the city and it would bring value to the businesses which would grow your name, and give those investors that want to invest in Houston a feel for the local economy.

I really like this channel because it showcases various types of investors and these investors range when it comes to quantity of portfolio.https://www.youtube.com/channe...

Make some videos showcasing what you know and how it can be applied to brokers, investors, etc.

This is a great graphic.
