Jerry,
The Comian presentation looks impressive, but there isn't a lot of history with a those numbers. The separately managed account isn't very mature so you don't see the problem childs in the numbers yet. I was taking a look at another presentation from another group of funds and their returns for several funds were around 11%, but that is before management and incentive fees. Assuming a 1.5% or 2% management fee and a 20% incentive fee significantly alters the returns to investors.
I went to a live auction in Mahwah, NJ recently. There were 40 certificates sold and the vast majority went for a premium. There was a $10.3k lien that went for 0% and a $50k premium. Another $3.4k lien went for 0% and a $14.9k preimum. There were plenty of others that went for 2-4x of a preimium. I understand being able to buy the subsequent liens and get 18%, but I really don't understand paying 4-5x of a premium and being able to make an adquate return?! Even lots were going for a 1.5x - 2x preimum.
Sure, this was just one auction, but I imagine that the same crew go to most/all of the other auctions in NJ (NJ does auctions by towns, not counties). Judging by just this auciton, I would not think NJ makes a lot of sense for individual investors buying liens.
