Is stretch senior cheaper than senior plus mezzanine?

Sometimes. Stretch senior charges one margin on the whole loan, usually higher than a senior margin and lower than a mezzanine one, and saves a second lender's fees and the cost of an intercreditor agreement. Senior plus mezzanine charges the low rate on most of the debt and the high rate on a small slice. Which costs less depends on the deal's size, the margins and fees offered, and the term, so borrowers compare the all-in cost of both.

How much can a stretch senior lender lend?

It varies by lender, asset, location and sponsor, and lenders quote it against different measures: loan to cost, loan to end value, or, in acquisition finance, a multiple of earnings. The defining feature is not a particular percentage but that the loan goes beyond what the same lender would offer as plain senior debt, into the range a mezzanine lender would otherwise fill, while keeping a single first-ranking position.

Does stretch senior need an intercreditor agreement?

Not with the borrower, because there is only one lender and one loan. If the lender later sells part of the loan or splits it with a co-lender, the lenders may agree their own arrangement between themselves, and the borrower may not be a party to it. A borrower that also has shareholder loans or vendor finance may still be asked to subordinate them to the stretch senior lender.

Why would a lender offer stretch senior rather than refer the borrower to a mezzanine lender?

To earn a higher margin on the whole loan, to keep the relationship, and to keep control. A lender that holds the top slice itself does not share the security with a second lender or negotiate with one in a workout. The cost is that it carries the mezzanine risk on its own balance sheet, with less equity beneath it, so it needs to be paid for that risk and to structure the loan to match.

Stretch Senior Debt: One Loan Doing Two Jobs

One lender, one charge, and a top slice priced like mezzanine.

BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED 2026-11-07

// THE SHORT ANSWER

Stretch senior is what a borrower asks for when its equity falls short of what a senior lender normally requires and it does not want a second lender in the structure. One lender advances more, against the same first-ranking security, at a single margin. The borrower saves the cost and delay of negotiating with two lenders and the agreement between them. The lender takes on the slice a mezzanine lender would have held, and reads the file accordingly: less equity to absorb a cost overrun or a fall in value, and more of the repayment resting on the sale or refinance at the end.

// 01 — WHY A BORROWER WANTS ONE LENDER

A senior lender sets how much of a project's cost, or a business's value, it will lend against first-ranking security, and the borrower's equity fills the rest. When the equity is short, there are three ways to close the gap: find more equity, perhaps from a partner who will want a share of the profit; add a mezzanine lender behind the senior; or ask one lender to stretch. The term is used mostly in property development and investment lending, and in acquisition finance for a single senior loan sized beyond the lender's usual multiple of earnings.

The appeal of stretch is simplicity. There is one facility agreement, one valuer, one monitoring surveyor on a development, one set of fees and one party to deal with when something goes wrong. There is no intercreditor agreement to negotiate, which on a smaller deal can cost as much in time as in legal fees. The price of that simplicity is a margin above senior pricing across the whole loan.

// 02 — HOW THE PRICE IS BUILT

A lender pricing stretch senior is pricing two risks in one loan: the part it would have lent anyway, and the top slice a mezzanine lender would have held. One way to frame the price is the blend:

Blended margin = (senior slice × senior margin + stretch slice × top-slice margin)

÷ total loan

The quoted margin can sit above or below that blend. Above, because the lender holds the whole exposure and may charge for the concentration; below, because it saves the cost of a second lender and expects to keep the relationship. On the borrower's side the comparison is the all-in cost of both routes, fees included, over the expected term. Neither route is cheaper as a rule; which wins depends on the deal's size, the lenders' pricing and how long the loan is outstanding.

// 03 — THE EXAMPLE

A developer, constructed for this page, plans a scheme costing US$20.0m, with an end value of US$26.0m. It has US$5.0m of equity. The lender's normal senior limit on this kind of project is 60% of cost. The developer can bring in a mezzanine lender for the gap, or ask the senior lender to stretch to 75%. Every margin, limit and figure is the example's, not a market norm.

US$m; margins on the loan once fully drawn

Total cost 20.0

Developer's equity 5.0 25% of cost

Route A: senior 60% + mezzanine 15%

Senior at 3.0% 12.0 × 3.0% = 0.36 a year

Mezzanine at 9.0% 3.0 × 9.0% = 0.27 a year

Interest margin 0.63 a year

Route B: stretch senior 75% at 4.6%

15.0 × 4.6% = 0.69 a year

Blend of route A: (12 × 3.0 + 3 × 9.0) ÷ 15 = 4.2%

Fall in end value before the lender's own loan is short:

As senior in route A: 1 − 12 ÷ 26 = 54%

As stretch senior: 1 − 15 ÷ 26 = 42%

Route B costs the developer US$60,000 a year more in margin once the loan is fully drawn, against the second lender's fees and the intercreditor negotiation it avoids. For the lender the project is the same, the developer's equity is the same and the total debt is the same; what changes is where the lender stands. In route A it has a mezzanine lender's US$3.0m beneath it. In route B it is that mezzanine lender, and its own cushion against a fall in values shrinks from 54% to 42%, before selling costs and the interest that will be added during the build.

Suppose construction then runs US$1.5m over budget and the developer has no more equity. In route A the intercreditor agreement sets who may fund the overrun or cure the default, and the mezzanine lender has its own money to protect. In route B the lender decides alone whether to lend more, and every dollar it adds sits on top of a loan already at 75% of cost.

// 04 — HOW IT DIFFERS FROM MEZZANINE AND UNITRANCHE

Mezzanine finance reaches the same total leverage with two loans and two rankings. The second lender has its own security behind the first, and the intercreditor agreement gives it rights the senior lender has to live with, commonly the right to enforce once a standstill period has run, a right to cure some defaults, and sometimes a right to buy the senior loan out. Stretch senior has none of that: one loan, one ranking, and no second voice in a workout.

Unitranche, used mainly in acquisition finance by private credit funds, is the leveraged-lending cousin: a single loan at a blended price covering what would have been senior and junior debt. In some unitranche deals the lenders split the loan privately into first-out and last-out parts under an agreement among themselves to which the borrower is often not a party. The borrower sees one loan; the lenders see two.

// 05 — WHERE IT DECIDES A FILE

The credit paper has to show the lender's position at the higher leverage, not at its usual limit with the extra described as an exception. That means testing the full loan against a fall in values and a cost overrun of its own size, reading the interest that will be capitalised on the larger balance, and asking what supports the top slice that would have supported a mezzanine loan: the sponsor's record, the depth of the presales on a development, and the strength of the exit.

The structure usually tightens to match. Lenders commonly ask for a cost overrun guarantee or a completion guarantee from the sponsor, tighter loan-to-value and cost-to-complete tests, and more frequent monitoring. Where a lender offers stretch senior at all, it is choosing to be paid for mezzanine risk, and it should be able to say why it would rather hold that risk than see another lender hold it.
