@John R Olson I've never heard of any of these funds or groups but can provide some general feedback.
1. From my experience, your 2 year max criteria will be fairly difficult to find. I'd suggest some flexibility on this as many funds (or individual asset deals, for that matter) project a 5-7 year hold but really end up exiting in 2-3 years.
2. 12-15% is also very good. Be cautious of any group that promises that. If current income is your primary objective, be sure to pay attention to preferred return and CoC. Often you'll see a pref (normally 7-10%, but in your case perhaps 10-12%) but the projected cashflow is more like 4-5% and the pref will be caught up at an equity event. Not saying this is bad, just something to consider.
3. I suggest considering splitting your investment up among your top 2-4 choices to spread risk and increase likelihood of continuous distributions.
4. I have a few groups/funds that may be worth considering but can't post publicly, feel free to DM me if interested.
