My point is even some experienced operators doing more extensive/sophisticated value adds are struggling in this market. 

Pros/Cons, contacts even maybe, for instance how do you even acquire a loan like this, or is it the same as hard money dealings.

The only instance in which that would be appropriate would be if they need payment flexibility, as most HELOCS only require a interest only payment.

For instance, property tax & insurance expenses.

Happy to contribute as needed as I have an extensive background in working with expats/foreign nationals real estate investors.

You give vague answers to specific questions.For example, when someone asks about potential rent, and they provide enough information for you, don't respond with an extensive range.

For instance, in the Netherlands, there’s considerable interest in the charming rural areas of Southern Spain.

Lease has double sided tape specifically cited that includes a charge for each instance.

For instance, cities like Chicago are known for landlord-tenant laws that skew heavily in favor of tenants, and that risk should be baked into your underwriting.What’s your take on balancing short-term cash flow with long-term equity growth?

It's a rather extensive "thing" now so probably a bit over the top for most.
