A deal that produced a 25% net IRR to investors with a 1% acquisition fee, 1% asset management fee, simply pref + single tier waterfall, etc, may only produce a 15% net IRR under the current fee and carry structure, if their acq fee went to 3%, pref went down, they now have a GP catchup and multi-tier waterfall giving them higher splits for higher returns, etc.

And one would have to get with the companies that produce these debt instruments to rewrite them.. most banks use the same providers for their legal docs.

When the money dries up, they'll leave just as quickly as they arrived and you may be stuck with a real mess.If it can produce more money as a short-term rental, do it yourself.

Real estate investments (STRs, MTRs, live in flips) have produced my best returns by a good margin.

Do you have any other income producing assets? 

I'm curious how something like that would work with land that doesn't have an income producing rental on it yet? 

Consider selling the duplex to put it into a higher income producing asset (out of state, DST, something).

@Mark Allen Hopefully, this gold mine is still producing.

The hedge funds and firms alone are buying more supply than is being produced. 

I do not have my numbers as well organized as @Greg Scott but my estimate is upper 20% annual return on average.The 3 i am currently invested in, one seems likely to produce an outstanding return (High risk, high reward), one is conservative and is performing to projections, and one i have significant concerns about but has not had a capital call.
