If the major banks say No to a property developer, they go to Judo, if Judo says No they go to Leftfield Capital? Don't know whether that's the model but, risk/reward.
I'd be concerned whether Leftfield have skin in the loan, or just get their margin without capital risk such that "closing the deal" is their prime motive.
Or worse a related party transaction which even if illegal or undisclosed, doesn't get the money back.
I was burnt once (50y ago, never forgot).
But sure I understand the pa maths starting point of an extra 4% if probability of default < 1/25 (<1/100 for 3month loan), accepting some capital losses.
