The lenders are actual sophisticated investors-
not the mums and dads or bloke down the pub who gets a letter from his accountant to qualify.
These guys are putting their reputations on the line and we can be sure that they have gone over AUC with a fine tooth comb.

A big thumbs up for this method of raising funds.
