As such specific financial operation vary from countries to country, there is no built-in feature to input this, but you
      can anyway setup and follow the reimbursement/profit with 2 or several accounts.
    Here is a way of setup and follow-up a loan for a house, it is setup into the example file as well:
We will setup 2 accounts:
    - the bank account, this is where the reimbursement will goes to the loan account
    - the loan (house) account, this is the loan itself
    - in this account, we input a first expense line with our loan total amount: -166 000.00 €
We will setup 2 recurring transaction separating refund and insurance:
    - refund: is a monthly transfer of -1053.45 € from 'bank account' to 'loan (house)' account
    - insurance: is a simple monthly recurring transaction of -33.20 € in 'loan (house)' account
The optional setup is not detailed here: payee, category, tag, clear, reconcile, whatever to fit you needs
As input each month fee will be painful, let's take benefits from the CSV import.
From your bank, or a website bank simulator, you will be able to get a full table of your loan with detailed fee.
      It is quite easy with a spreadsheet program to rearrange this to HomeBank CSV file format.
    Then, just import this fees into the 'loan (house)' account.
In the main window
      - 'Your account' shows the remaining due amount, with cleared, reconciled and future depending on your configuration.
With time report
    To view progression, 2 option:
    - tick 'Cumulate'
    - select 'loan (house)' account only
With balance report
    - select 'loan (house)' account only
  
Et voilà !
  You can also use other report with appropriate filter/display configuration
