Individual - Portfolio Managemente -- After tax nominal

[cipherap15]

We have AFter tax mortgage payments = 55 000 coming out of portfolio. PV of portfolio = 10,200,000, N=5 and FV = 15M.
Get an interest rate of 8.43%.
I’m assuming this would be AFTER TAX and NOMINAL. Is that sound right? Cause it’s a portfolio value we need it has to be Nominal and because after tax payments are coming out – its After Tax.
Thanks
