I bought an LG TV a few weeks ago, was on the LG site, asked a question on the chat, and they offered 20% off without even asking (on top of the sales price).

The result for a background check using Zillow Rental Property Manager's site came back with a result of "N/A".

Joseph, the best method for you would probably be the MLS or sites like realtor.com etc.

I own a duplex property (I do not live on site) and I'm renting out the 2 bed/1 bath back house.

While both involve finding and properly securing a site and bringing it to full entitlement, the ground-up process includes the land piece but gets way more involved and complex to execute.The full "Monty" for ground-up development needs to include financial literacy, an explanation of metrics, and how they work.

I couldn't find anything too specific on the site.

Alerts I set up through sites like Realtor.com or Zillow. 

Gross profit is interesting because it appears to just be the difference in his acquisition and sales price and fails to take into account the other obvious cost of running that business which includes, again according to him, the cost of over 26,000 letter print, mail, post, and the cost of the lists needed to create a mailer of that size. 

Seems like 130 units is a beast to manage, I'd love to hear about your on-site management systems and "experience management" process to stand out amongst the fierce competition in the smokies. 

There are sites out there like passive pockets as well as this site where you can find out a lot from people who have invested with that fund.
