We will choose our general contractor based upon reputation, references from my own commercial construction contacts (I have held a LA State - Building Construction license since 2001), their solvency, then finally their proposed bid.

Within a couple of years, he owned 10+ doors. 

We currently own a duplex and live in one of the units.

I personally don't contact any of the people off this, list, although i don't see why you couldn't?

I don't know Greg personally, but tends to be direct when I see him on the forums.

I have learned to completely disregard articles like this and just constantly be checking my own statistics for my property and watch for trends.

Personally and professionally, I'm craving connection more than ever (it has been a long, weird 10 months and I miss our local meet ups).

I would like to sell a second position mortgage portfolio I own. 

Just be sure to run your own numbers and do your own due diligence before investing in their properties (which you should always do). 

I personally haven't used Latchels service but as I look to scale, its a route I am looking to explore.
