However, Montgomery County as of yet has not updated their forms or website, included the landlord/tenant handbook and they are still not enforcing.

And the PMs and realtors I know don't want to talk to a website.

Quote from @Kimberly Venable: Good morning, I have been a lurker of this website for a while.

Here's a https://www.irs.gov/businesses/cost-segregation-audit-technique-guide-chapter-4-principal-elements-of-a-quality-cost-segregation-study-and-report to the IRS website noting specific items that are included in the cost segregation study report. hmm, that website is a 404 error.  

No, I've not invested with SCDC, and it's not likely I will without evidence they can do / have done what they've claimed on their web site.

Quote from @Chris Lo: Which platforms/websites do landlords use to find the rent rate, how long the rental properties have been on the market, and all the details about other rental properties?

For example, to get up-to-date property tax data you would need to scrape every county's tax data website (thousands of different websites, data formats, issues, etc...) then aggregate and clean the data.

I tried to go to the website referenced, but it gave me a 404 error.

Seems that the website Fourpeakspartners.com is not working any longer.

There are a lot of websites that offer the course online, or if you have a college near you, they also typically offer a class that satisfies the pre-licensing requirement.
