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.)?

You can also check meetup.com or search Facebook for real estate investment groups, clubs, or meetings in your area.
