I think banks have a good idea these days about what their portfolios are really worth. Now their problem is how to unload them. I think this is why we have all the stalling going on right now from both the govt and the banks. Foreclosure moratoriums, non-processed NOD’s, etc….
There’s no avoiding reality if a transaction takes place that makes the property value come in-line with the market value. And they know this. Hence the delaying tactics. Kinda like a prisoner on death row. The appeals can go for a very long time. And almost all of them do it.
