Some assets carry external loans that are not policy loans — a mortgage on a rental, a HELOC behind a primary, an SBA loan on a business, a margin loan on a brokerage account. Policy Stack tracks these as liabilities linked to the deployment.

Funding vs. Liabilities
These are two different records and they show up in different places:
- Funding sources describe how the asset was acquired — recorded once, in Step 4 of the Add Asset wizard. See Funding Sources for a New Asset for the full walkthrough.
- Liabilities describe ongoing loans attached to the asset — recorded on the deployment detail page and updated over time as balances and payments change.
A property bought with a policy loan and a mortgage has both: a policy loan funding source (recorded once at creation) and a mortgage liability (tracked on the detail page for the life of the loan).
Where Liabilities Appear
Policy Stack uses two surfaces for asset-attached loans, depending on the asset type:
- Real estate assets render a Financing card with property-specific tiles — current balance, monthly PITI (principal + interest + escrow), interest rate, and projected payoff date. Real estate has its own surface because mortgage tracking carries property-specific UX (PITI roll-up, equity built) that doesn't generalize cleanly to other asset classes.
- Every other asset type — business, equipment, syndication, promissory note, securities (stocks, ETFs, crypto, bonds, mutual funds, precious metals), and other — renders a card. The linked-liabilities card supports zero, one, or many loans per asset and shows the same key fields per row: current balance, monthly P&I, interest rate, and payoff.
