No syndication experience but there are about a dozen quality RV/Mobile home parks on market in Oregon, several with owner carry options that can be passiv-ish with management in place.

As a foreign investor, I can get financing up to 80% for the purchase of real estate, so the biggest problem for a more serious project is down payment if you have a solution for down payment, please suggest me. 

If you can't find a good manager, walk away.

Quote from @Jacklyn Robins: You've "never" had this issue, but you've only managed a few properties for five years.

For a truly passive experience you'd probably need to be an investor in private equity deals or be a silent partner on a project.

My job is our sole income and I get relocated for projects frequently so any property would have to be managed remotely (willing to invest anywhere in the states).Given the our situation above and our long term goals, I feel best next steps would be a heavy emphasis on networking and deal analysis.

I’m looking to invest in nearby areas, focusing on fix-and-flip projects and new ground-up construction.

I reached out to another GC, and he said the same.The project itself isn’t complex, but I planned to redo the wiring, plumbing, and remove some walls.

Hey Matt,I’ve been investing and managing properties for over 20 years, and choosing the right market is key—especially as a new investor.

Wish we would have fully completed each project before moving onto the next.
