PBSA Mezzanine Finance

How mezzanine debt sits between senior loans and equity in UK PBSA — cost, leverage, intercreditor risk, and when it makes sense.

What is PBSA mezzanine finance?

PBSA mezzanine finance is subordinated debt for Purpose-Built Student Accommodation that sits between first-charge senior debt and equity. Senior lenders cap leverage on LTV and DSCR; when that cap binds before your equity budget does, mezzanine fills the gap — at higher cost and with more legal complexity.

It is not a residential top-up mortgage. Mezz providers underwrite the same asset story as senior lenders (occupancy, rents, operator, location) plus their recovery position if the deal goes wrong. For senior product mechanics, see student accommodation loans; for when equity is the better fill, see PBSA equity funding.

When mezzanine fits a PBSA deal

SituationWhy mezz shows upWatch-outs
Equity stretch on acquisitionSenior at 60% LTV; sponsor wants ~20% equity not 40%Blended cost and DSCR under rate stress
Value-add / operator changeIncome upside not yet proven for full senior LTVLease-up risk; mezz term vs business plan
Tight refinance / recapNeed temporary leverage above senior appetiteClear take-out or sale within mezz term
Development equity gapLTC shortfall vs sponsor cashOften dearer than JV equity; rare vs stabilised mezz

Mezz works when the hold or refinance clock is short enough to repay or refinance the mezz tranche. Rolling expensive mezz without senior take-out is one of the common financing mistakes on the PBSA financing hub.

Indicative mezzanine terms

Ranges below are market norms for planning — not quotes. Live pricing depends on city, sponsor track record, operator, and how far total leverage sits above senior appetite. Cross-check bands on the PBSA finance rates page.

Intercreditor and security basics

Adding mezzanine means two (or more) debt parties must agree how cash, covenants, and enforcement work. The intercreditor agreement typically covers payment waterfalls, standstill periods, cure rights if senior covenants breach, and who controls enforcement of security.

Budget legal time and cost before you treat a soft indication as done. A cheap mezz coupon with hostile intercreditor terms can be worse than writing more equity. Senior lenders often require consent to any subordinated facility — involve them early.

Worked example — equity stretch with mezz

On a £10m stabilised purchase, senior lenders cap at 60% (£6m). The sponsor wants to write a £2m equity cheque. Mezzanine of £2m fills the gap (80% total leverage) at a higher coupon — often in the 8–15% p.a. range — until a sale or refinance reduces the stack.

Blended cost of debt rises versus senior-only. Stress-test rents, voids, and rates before you commit — use the finance calculator for a first-pass senior + mezz cover check, then validate with term sheets.

Exiting and refinancing mezzanine

Plan the mezz exit on day one. Common paths: refinance onto a higher senior LTV once income is proven, sell the asset, or inject equity to repay mezz. Leaving mezz in place past its intended term usually means expensive extensions or default risk.

If the end state is a cleaner investment loan, align with the PBSA refinance timeline so mezz maturity and senior take-out do not collide.

Mezzanine vs writing more equity

Choose mezzanine when…Choose more equity when…
Equity cheque is the constraint and exit is clearHold is long or cash flow cannot service blended debt
Temporary leverage until refinance or saleYou want simpler security and fewer parties
Value-add upside can repay mezz within termSponsor wants maximum downside control / first-loss clarity

Common mezzanine mistakes

Comparing coupon only

Arrangement fees, exit fees, and senior margin changes move all-in cost more than a small coupon difference. Compare full term sheets.

No modelled exit

Mezz without a refinance or sale case is expensive bridge risk. Model take-out LTV and timing before you sign.

Agreeing mezz before senior consents

Senior lenders often must approve subordinated debt. Soft-sound senior and mezz together so intercreditor is not a last-week surprise.

FAQs

What is PBSA mezzanine finance?

PBSA mezzanine is subordinated debt that sits between senior first-charge debt and equity. It increases total leverage when a senior lender’s LTV cap binds before your equity budget does, at a higher coupon and with intercreditor complexity.

What does PBSA mezzanine typically cost?

Indicative pricing often sits around 8–15% per annum all-in depending on sponsor, asset, and security. Arrangement fees and exit fees are common. Always model blended cost with senior debt, not mezz coupon alone.

How much leverage can mezzanine add?

Senior debt on stabilised PBSA commonly caps around 55–65% LTV. Mezzanine can stretch total leverage toward roughly 70–80% of value on suitable deals — subject to DSCR, intercreditor terms, and exit path.

When should I use mezzanine instead of more equity?

When you have a clear refinance or sale within the mezz term, the equity cheque is the binding constraint, and blended debt service still clears lender stress tests. If hold period is long or cash flow is thin, more equity is usually cheaper than rolling expensive mezz.

What is an intercreditor agreement on PBSA mezz?

It sets payment priority, standstill and cure rights, enforcement control, and how senior and mezz lenders interact if covenants breach. Legal cost and negotiation time rise with the stack — budget for it before heads of terms.

Can I use mezzanine on PBSA development?

Sometimes, alongside development senior debt, when equity is short of LTC requirements. Construction mezz is rarer and more expensive than stabilised mezz — many sponsors prefer JV equity or forward funding instead. See development finance and equity funding guides for alternatives.
