A long term problem still unresolved after ten years is that Quicken Mortgage-Backed Bond Security Valuation doesn't Match Schwab Valuation. Anyone who has FMNA, FHLC, or other mortgage backed securities will have this problem.

I received the following response from Schwab regarding why values are different. When will Quicken update value?
"I talked with Schwab, Fjolla and our Dave who is on our Fixed Income Trading Desk regarding the fixed income of FHLMC 5.5% SB8235 06/01/2038 and why QUICKEN shows the market value of $45,517.85, but Schwab shows $39,828.16.
The market value is based on the current pool factor of 0.87500097 which will go down every month as mortgages in the pool are being paid off. A new factor will be out on Monday.
This Example: Purchase price of $45,517.85 multiply by the Pool factor of 0.87500097 = $39,828.16
They unfortunately did not have information on if/when Quicken would update.
