Capital tied up in Illinois but a Chicago deal sits on my desk and I need to decide in the next two weeks

The intercreditor is where this actually lives or dies, not the coupon.

Senior lenders on Chicago mixed-use have killed mezz deals at 90 LTV because their docs say no subordinate debt without consent, and getting that consent added three weeks I didn't have on a similar situation.

What's the senior lender's position on mezz in the stack?

The back-end split concern is the right place to focus your discomfort, and here is the arithmetic that makes it concrete: on a 24-month hold with a 485k preferred equity piece at 17 percent annualized, you are paying roughly 165k in preferred return before the split even starts, whereas mezz at 12 points on the same balance over the same period costs about 116k in interest, and you keep all the appreciation. The spread widens further if your refinance comes in at month 30 or 36 rather than month 24, which is a realistic stabilization assumption on a Logan Square mixed-use where the retail component can drag.

The part worth stress-testing before you pick the structure is what the senior lender's intercreditor terms actually permit. Some senior lenders at 65 LTV will allow a mezz pledge of the borrower's ownership interest with a standard cure right, and some will not allow any subordinate debt on the entity at all, pushing you toward pref equity structurally even if you prefer mezz economically. If the senior lender's term sheet is silent on subordinate financing, that silence is not permission, and you want a written carve-out confirmed before you spend two weeks negotiating a mezz commitment that cannot close.

What does the mixed-use income look like right now, specifically the retail vacancy and what lease terms exist on the residential side? That stabilized NOI number is what determines whether a mezz lender at 12 points sees this as a yield play worth doing at 90 percent of value, or walks.

The piece nobody talks about: mezz lenders on mixed-use near Logan Square have been adding a lockout clause that survives your refi window.

The detail that changes the pref equity math on a 24 to 36 month hold is whether the preferred return accrues and compounds or accrues and simply. A pref partner quoting 15 percent looks cheaper than mezz at 12 until you find the sentence that reads "unpaid preferred return shall accrue and compound monthly." On 485k at 15 percent compounding monthly over 30 months, you are looking at roughly 214k in accrued return before you touch the back-end split. The same capital at 12 percent simple mezz runs about 175k in interest over that window, and your equity stays whole. The coupon spread between the two options is doing less work than the compounding mechanic, and that mechanic lives in one sentence of the operating agreement, not the term sheet.

The piece worth adding from the mezz-as-lender side of your experience is that the intercreditor agreement on mixed-use in Illinois will almost certainly require the senior lender's written consent to the mezz position, and Chicago mixed-use with any ground floor commercial component sometimes triggers a lender restriction on mezzanine debt entirely, pushing you toward the pref structure by default rather than by preference. Before you spend two weeks modeling the cost difference, I would ask the senior lender directly whether their commitment letter permits subordinate debt at all, because if it prohibits mezz outright, the decision is already made. Do you have the commitment letter language in front of you yet, or just the term sheet quote?
