Delboy; Without a doubt some chanchers will play this and get through the net. However Ptsb and the rest have had 4 years drilling into accounts so should know the chanchers V the hopeless.
I would think Ptsb know that an unforced sale is less costly to them than legal eviction on these hopeless cases,it lets ptsb take a clean hit and lets genuine hopeless cases move on.It should also identify messers.
I would expect Ptsb etc to do solid checking to see if these hold other assets and put a clause in to the effect that if hidden assets are found it will be war !.
