Junior Debt, Mezzanine Finance and NAV Loans for Real Estate, Explained

Real estate investors looking beyond a senior mortgage usually hear three terms: junior debt, mezzanine finance, and NAV loans. They solve related problems in different ways, and choosing the wrong one costs real money. This guide explains each, in plain terms, from the perspective of a lender that structures portfolio-level credit.

What is junior real estate debt?

Junior debt is any loan that ranks behind the senior mortgage in the repayment queue. If a property is sold or defaults, the senior lender is repaid first, and the junior lender takes what remains. Because junior lenders absorb losses first, they charge more. Junior debt appears in several forms, including B notes carved out of whole loans, second-charge mortgages, and the lower-rated tranches of commercial mortgage-backed securities.

What is mezzanine finance?

Mezzanine finance is the most common form of junior real estate debt. It sits between the senior mortgage and the equity, and it is usually secured on the shares of the property-owning company rather than the property itself. Developers use it to push total leverage above what the senior lender will provide, typically on a single asset or project. Pricing reflects project risk, and terms are usually tied to a specific business plan such as a development or refurbishment.

What is a NAV loan against real estate?

A NAV loan takes a different approach. Instead of lending against a single building or project, the lender advances credit against the net asset value of an entire portfolio. For a family office that holds several property companies, real estate fund interests, or a mix of direct assets and fund positions, the NAV lender looks at the whole book: independent valuations, rental income, existing senior debt, and diversification across assets and geographies.

Security is taken through pledges over equity interests and distribution accounts rather than mortgages over individual buildings, which means existing senior facilities usually stay exactly where they are. The borrower keeps ownership, keeps the upside, and gains one flexible facility at the portfolio level.

How the three compare

Scope: junior debt and mezzanine are asset-by-asset. A NAV loan covers the portfolio.

Security: mezzanine takes share security over a single property company. A NAV facility takes security across the portfolio structure, usually leaving senior mortgages untouched.

Pricing: single asset junior debt is priced for concentrated project risk. A diversified portfolio can often achieve better pricing on a NAV facility than the same borrower would pay for mezzanine on each project, because diversification lowers the lender's risk.

Speed and simplicity: raising mezzanine on five projects means five negotiations, five intercreditor agreements, and five sets of legal fees. One NAV facility replaces all of that with a single process.

When each one makes sense

Mezzanine or junior debt fits a single development or acquisition where the business plan needs leverage beyond the senior loan and the sponsor accepts project-level pricing for it.

A NAV facility fits an investor who holds multiple assets or fund positions and wants liquidity at the portfolio level: to fund a new acquisition without selling, to bridge timing gaps, to refinance expensive project-level junior debt, to release equity trapped behind fixed-rate senior loans, or to fund commitments across the portfolio.

What a real estate NAV facility looks like in practice

Nodem Capital structures NAV facilities from $15 million to over $100 million against real estate portfolios, including real estate fund interests, property holding companies, and mixed books of direct and fund positions. Loan-to-value ratios of up to 30% of independently verified net asset value are typical, and real estate portfolios can often achieve higher levels than private equity portfolios because the underlying assets carry independent valuations and contracted income. Facilities run one to five years with cash pay or PIK interest, and a term sheet typically arrives within two weeks.

A recent example: a $30 million NAV facility for a UK real estate family office, secured across the family's property portfolio rather than any single building. The full case study can be found here.
