If the goal is simply to better understand the commercial landscape, values, and happenings, skip buying any course and start subscribing to the Business Journal for your closest major metro.

But the Wall Street Journal had a favorable feature on him in July. 

No personal experience here but here's a helpful reference from someone who wrote a blog about different aspects of a 2 flat remodel in Chicago Scroll to "Two-flat journal 6: How to make an all-electric house" - - speaks a little about heat pumps and cost In the HVAC section.  

@KEITH CUDDEBACK Thank you for post this very help i begin my journal in real-estate and wanted to know the same question 

Subscribe to the business journal in that area to keep abreast of local business developments.

Is it a journal, word document, voice notes? 

I talked the brokerage into paying for an ad in the Houston Business Journal announcing that I, a “specialist” in automotive properties had joined the brokerage.

Now when the house sells, I post a journal entry to move that $500 to COGS.

This reminded me of a Wall Street Journal article that came out about a month ago.

I moved this post into that forum, for example.You can see plenty of thorough discussions there and it is just ramping up.We also plan to do more investigative style journalism, come this summer with PassivePockets.
