It's actually not that difficult to decipher.
The basic premise of securitization is that the isolation of loans from the bank's (or lender's) balance sheet will allow pricing of *only* those loans, rather than the bank in general. This has reduced risk-spreads on mortgages over the last 40 years and has streamlined financing. The last 5 years aren't the greatest indication of how well the system works, the prior 35 years is.
Ultimately, the payments are being routed correctly and people are paying down their mortgages or are being foreclosed upon.
This bunk about the note not following the mortgage is bunk. It hasn't largely been supported by case law. The banks can (and do) prove that they own the note, or the trust does, in many different ways. The note doesn't need to be an original.
As far as the robosigners, the people didn't pay. They know they didn't pay. The banks know they didn't pay. If you don't pay your contract says the bank can take the property.
Good post (along with the later posting of the white paper) which I mostly agree with in principle, but the bolded part above is a substantial overstatement. A mortgage note is a negotiable instrument and as such it is transferred by negotiation and physical transfter. Think of cashing a paycheck, you transfer it by endorsing the back and handing it to the bank teller. That instrument now belongs to the bank.
There is an exceptional to the physical possession rule under the UCC for lost, stolen or (inadvertantly) destroyed notes. From personal experience, quite a few lenders have grossly abused this exception for decades in foreclosures in seeking to excuse their duty to prove to the court why they can't produce the physical original note.
Given the huge dificulty many people have these days confirming either which entity actually owns their note and mortgage-or more importantly, which entity is servicing them (ie, collecting the payments and negotiating forebearance agreements) it is my view that the courts should take a strict view on requiring the lender to produce the original note or a very good reason why they cannot.
Try to get a replacement for a bank check you inadvertantly destroy sometime and see the hoops the bank makes you jump through (usually including posting a bond) and tell me why what is good for the goose shouldn't be good for the gander.
In theory, the MERS system is a great idea to avoid unnecessary recording expenses, which can be quite big. But in practice it's way too vague right now.
BTW I had a lot of involvement in representing lenders in foreclosures in the late 70s and early 80s. The whole robosigning thing is nothing new by a long shot-but as LegendKiller correctly points out, it is nearly always meaningless and causes no harm to the homeowner.
