I'm using Quicken Classic for macOS.
My mortgage is set up as a Liability account. Each month, when I pay my mortgage, the payment is recorded as a transfer from my checking to the liability account. I then manually add my interest and escrow expense to the liability account, which makes the liability account's balance match the balance on my mortgage.
To visualize, using imaginary numbers:
Mortgage account:
Feb. 15 balance: $250,000
Feb. 16 payment: -1,500
Feb. 16 escrow: +200
Feb. 16 interest: +700
Feb. 16 balance: $249,400
The problem is that in any reports, the escrow and interest show up as expenses but the payment towards principal (the difference between the total payment and the interest/escrow) does not.
I'm wondering if I should set things up differently and how you all handle this.
