Debt that ranks behind senior debt in payment priority.
Subordinate debt is any loan that ranks behind senior debt in priority of payment. Common types include second mortgages, mezzanine loans, and seller carry-back notes. Subordinate debt is paid only after senior debt obligations are satisfied — both in regular monthly debt service and in default / foreclosure scenarios.
Subordinate debt fills the gap between senior debt and equity in the capital stack. The most common forms: second mortgages (second liens on the property), mezzanine loans (secured by LLC interest pledge rather than property), seller carry-backs (seller financing that's subordinate to senior bank debt), and preferred equity (technically equity but functionally subordinate to all debt).
Because subordinate debt is junior to senior debt, it requires higher returns to compensate for higher risk. While senior debt typically prices 6–10%, subordinate debt prices 9–18% depending on layer and structure. The pricing reflects the simple math: if a property fails and senior debt is owed $1M with property value of $1.1M, the subordinate lender has only $100k of equity cushion below them.
Intercreditor agreements are critical on subordinate debt. They govern the relationship between senior and subordinate lenders — specifically: standstill provisions (subordinate lender can't take action during senior default cure periods), turnover provisions (subordinate must turn over any payment received during senior default), and cure rights (subordinate may have the right to cure senior defaults to protect their position).
For borrowers, subordinate debt is a tool for stretching leverage. A property that supports 75% LTV in senior debt but the borrower wants 85% total leverage might add a 10% second mortgage or mezz layer. The trade-off is cost — the 10% additional leverage often costs 11–15%, compared to 7% on the senior. The math has to work on the deal's overall returns to justify the higher blended cost.
| Property purchase price | $2,800,000 |
| Senior debt (75% LTV) | $2,100,000 @ 7.25% |
| Subordinate second mortgage (10% LTV) | $280,000 @ 12.0% |
| Borrower equity | $420,000 |
| Combined leverage | 85% LTV |
| Senior annual debt service (P&I) | $172,200 |
| Subordinate annual debt service (IO) | $33,600 |
| Total annual debt service | $205,800 |
| Blended cost of debt | ~8.6% |
Any loan that ranks behind senior debt in priority of payment. Paid only after senior debt is satisfied, both in monthly debt service and default scenarios.
Second mortgages, mezzanine loans, seller carry-backs, and preferred equity (technically equity but functionally subordinate to all debt).
Higher risk — the subordinate lender gets paid only after the senior is fully satisfied. In default, the subordinate lender has thinner cushion of property value below them. Higher risk requires higher return.
The agreement between senior and subordinate lenders governing their relative rights — standstill, turnover, and cure provisions in default scenarios.
When senior leverage isn't sufficient to fund the deal and the cost of additional subordinate debt (10–15%+) is still less than the cost of additional equity dilution to LP investors.
