Haven't done this myself BUT have a friend who worked for institutional players and has been on the buyer side for this.

That’s why I want to build my team now so I can start the process with all of the players involved.

Being in a situation now where I'm on the cusp of making my first move, I'm considering all my possible strategies, and lots of players have come my way wanting to buy the property I have as is, some willing to form a JV and provide funding for the investment. 

I'm still learning all of the players and their roles so any info on that would be helpful!

On the other side if you sell now you can use the money to invest in your next project.We do have some big players here on the site, and I am just the tip of the iceberg but this is my experience.

Check on the major agent fb groups - there are some big players that still do this.

You just have to decide which player you want to be in this game: The Passive Investor or The Syndicator.  

There are indeed some differences with the overall process as most real estate laws are more closely related to how things are done in Spain vs the US but most banks deal with the same players ( Fannie Mae,  HUD, VA etc) that you find in the states with a few twists..

I don't know how many folks follow the growth of Salesforce over the past 20 years, but they're THE big player in the CRM industry. 

I believe Angie's List is kind of the big player in that regard.
