Do not deal with any of the individuals mentioned in this thread:https://www.biggerpockets.com/...I outline my experience and many others weighed in. 

Personally I’d prefer having all my loans with one entity like my local credit union who doesn’t sell them and just have the payments come out of my account that I already have with them, keeping it as simple as possible. 

What i would recommend is joining a REA or other real estate meet-up group where you can connect with other likeminded individuals consistently and share knowledge.

Personally, I would prefer to use the HELOC approach.

If you are receiving 3-5 per week that’s not bad, considering the price is what most individuals look for when looking to rent.

Talk to a CPA who specializes in real estate; they can guide you on the best structure.Decide on Your Payout MethodPersonally, I prefer a mix of methods.

Denver and its surrounds have particularly active markets and a lot of active individuals offering ancillary services so I'd suggest you research those available services you're looking at offering to help you get an idea for what is well covered, what is lacking and what your competitor's pricing looks like.

I prefer the forum used for investors with actual questions.I am not a fan of what you call reverse trolling.I am not a fan of posts in the forum which have no questions and are basically blog posts.

They prefer to purchase a duplex in a C location because they have read a book about the 1% rule and/or the BRRRR rule.

Most foreign buyers are high net worth individuals who want to park their money there in a safe haven and they don't need BP.No restrictions apply to American buyers in the countries they'd generally want to buy, including those mentioned by Federico and many other popular countries.When it comes to Spain specifically, some more conservative banks will ask you for a 40% downpayment (that would be the maximum) but that isn't the rule.
