Of course, the owners don't offer to compensate the agents in anyway...Not sure what is the "fsbo website" but whatever you learn better be State specific, if not your portion of the state. 

Hard enough to operate effectively long term, gotta be compensated for that effort.

As a last resort, I would even be willing to lease the land, provided that I be compensated for the improvements when it sells.TIA

I think that you would have to understand what you are trying to accomplish before discussing compensation.

In the marketing, the justification for an interest rate of up to 20% is that the peso would depreciate against the USD, whereby you'd actually have to repay less and that would compensate for the sky-high interest rate.

Don't fall victim to doubling your project cost through unnecessary financing.

Just like Madoff did for his victims.

You may have other non-financial costs associated with this type of property that compensate for the greater cash flow (e.g. additional risk, needy tenants, tenants whose priorities do not leave room for taking care of your property, etc.). 

Now with a mixed compensation system??? 

If you do not deliver that may expect compensation, and Airbnb currently would take 30% of your money.
