Otherwise, I've noticed that all the core principles are the same for investing in Europe (US and European laws are pretty similar most of the time when it comes to business, usually just a different label or a little different twist).  

Core t me if I'm wrong, but an a corp is an LLC that first is converted to a c corp then elects to be taxes as an a corp. once you are a c corp then personal assets are at risk.

Essentially some of the core ideas would be to show the Borrower did not get served properly or was not afforded the 20 days to cure the default.  

's spreadsheet is really compelling, but doesn't include any PM.  

You may be able to find a small increase in price simply due to your return target being higher than the down stream buyer but I would not suggest you try and use that as a core part of your plan.

What would compel me to look into MH real estate?

I see stuff trading at a 5 cap in urban core Atlanta which is nuts and I would never touch such investments.

The core issue there for me is the fee is not net of sale but on top of sale.

You are of course limited by state usury laws in the interest rate you charge, but I can't imagine that there'd be a compelling government interest to limit how many private loans you could sponsor.

This is an interesting one and likely the big fat core problem.
