PBL 20 How much will we get back?

I've also got 1p invested (for the updates - used to based for avoiding loans I disliked)

Actually, It's the 3rd 1p I have invested.  I had 1p invested when the default occurred and it sold a couple of days later (just before the red box was applied), and the second 1p sold 20th of September.  My current 1p is 19k in the queue

 .... sometimes I wonder why I bother with all this DD lark 

Incredible. Who is buying? Supreme optimists? SS?

If there is 77k for sale why does it say all loans are fully funded on the available loans page?

It's under the Default TAB.  It used to be in the available loan TAB, but SS created a dedicated TAB for defaulted loans (which, from a business minded POV is a good move; no point having a defaulted loan on the first page you land on when signing in to SS  )

They hid it under default page, so now it is difficult to sell.

Because it is a safer investment than several other loans.
There are a number of different loans where receivers have been instructed and the reality is those lines are in a similar position to this one. The only difference is that they have put this one under the defaulted loans tab and let the others under the main tab. The reason this line has better prospects than some of the others is because it is the only loan involving receivers where saving stream have stated clearly in writing that interest will be paid at the end when it is all sorted out. It would be a normal us for them to pay interest on people's Investments but not return the actual Investments on which the interest was accrued. Therefore this loan has a higher priority in the payout packing order because you have the written guarantee on this one which you don't have on certain others and that is why I believe many investors are happy to continue to hold it because even though they don't know when they will get there investment and all the interest they no they will get it and the same cannot be said for a few of the other loans.
The only Circumstance in which people would not receive their 12% would be in the event of the whole platform failing and saving stream not having the money to pay out but if that were to be the case the whole thing would be kaput so again this particular loan is not at any greater risk
It goes without saying that other loans with long terms where receivers have not been appointed are better bats but at a time of famine it's still a good deal if you don't mind waiting an unknown period of time to get your money and interest

I'm most certainly NOT invested in this loan, but nevertheless I think that it will probably pay out in full plus interest. It will most likely take a big chunk out the SS provision fund, but I think that it will be worthwhile for SS in terms of platform credibility.  SS will still then be able to claim "no investor has lost a penny  etc etc"  and that will be worth a lot to them in terms of investor confidence.

However I did use the word "probably" above, which begs the question "Is PBL020 worth a gamble ?". Personally I think not, and it's much better to be patient and pick up what we can of longer dated loans , or of course, invest on an other platforms.
