I'm relatively new to this and am grateful for any advice from the forum. 

Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.

There's a ton of members where the sole contribution to these forums are endorsements of RTR.

Another lesson is to research companies online and in forums like this before you do business with them and if you decide to do business with someone, dip your toe in the water slowly and continue to research the company after you start working with them, because things can change quickly.I have some questions:1. 

I've used the search feature on this forum but didn't have much luck.Are there any US investors, hard money lenders, or groups that invest in flips outside of the United States, specifically in Europe (Netherlands, Spain, etc.)?

I want to become really good at analyzing deals, and determine the markets I should focus on.Are there any resources aside from this forum (books, journals, news publications, podcasts) that you recommend I use to learn more?

Stay for the forums, avoid the Bigger Pockets upsells and you will be golden.

I would recommend leveraging the BP forums to connect with existing syndicators.

I admit having some trouble searching for team members in the forum so hopefully BP guidelines will allow user referrals or intros.
