My Memphis preferred equity paid out 14 percent annualized and I want to talk about why the basis mattered more than anything else on this one

The assumption doing the most work in your stack was not the lease-up speed or the finish quality, it was the $19 foot basis absorbing a $2.1M mechanical overrun without breaking the preferred coverage. That is the cleaner version of the adaptive reuse thesis at institutional scale: a distressed seller's urgency transfers directly into your margin of error.

The risk you did not name is structural feasibility correlation. The same floor plate and plumbing characteristics that make an office building cheap to acquire often make it expensive to convert, and in your deal those two things happened to offset cleanly. At $19 a foot, there was room. The building at $65 a foot is not just a basis problem, it may also be a building that was priced higher because it converts more easily, or it may be a sponsor who paid too much and is now telling a story about conversion upside to justify the number. Those two situations require very different diligence, and from the outside they look similar.

The other thing worth naming is extension optionality. You got 24 months on what was nominally an 18-month term. That extension feature was structural protection, and the fact that it got used once without triggering a problem means the sponsor had genuine execution discipline. A lot of preferred positions in conversion deals look fine on paper until the second extension hits and the construction lender starts asking questions. Ask your lender what current extension mechanics look like on preferred structures in adaptive reuse and confirm those terms in writing, because the standard has been moving.

One question: when you are underwriting the $65 foot deals you are passing on, are you seeing sponsors who have accounted for the full conversion cost per unit, including MEP and egress, or are the pro formas still treating mechanical as a soft contingency line?

The $19-a-foot acquisition is doing a lot of work in this story, and you explained why clearly. When the basis is low enough, the deal has room to absorb what goes wrong without wiping out the people sitting in the preferred position (the layer of the investment stack that gets paid before the sponsor earns profit but after the senior lender).

The mechanical rough-in overrun is a good illustration. Conversion projects regularly hit unexpected costs in the wall and ceiling cavities of old commercial buildings because nobody fully knows what is in there until demolition opens things up. A sponsor who paid $65 a foot has almost no cushion when that happens. A sponsor who paid $19 has $2.1 million worth of cushion, apparently, and your preferred still cleared.

The one thing worth naming for anyone reading this who is earlier in their learning: a 14.1 percent annualized return on a preferred position is a real outcome on this deal, and the basis protected it. It is not a projected outcome or a standard that institutional preferred equity delivers generally. The building, the market, the seller's situation, and the timing all lined up in a specific way. Someone reading this post who goes looking for "office conversion preferred at 14 percent" should understand those inputs are part of the return, not incidental to it.

The point about smarter sellers is worth underlining. Distressed pricing usually requires a motivated seller. When the seller has already figured out they can wait, the distress is priced in and the edge disappears.

What is your current screen for identifying which office markets have enough residential demand to support conversion lease-up at the pace this medical district showed?

What did the sponsor's GC relationship look like before the mechanical overrun hit?

The $2.1M overrun absorbing cleanly is the part I want to sit with, because every passive deal I have looked at where the sponsor framed a cost overrun as "manageable" had a basis problem underneath it, not a construction problem. They were managing perception, not cushion. What actually happened was the preferred got deferred or the sponsor came back asking for a capital call framed as an "opportunity" to protect your position. The only thing I have never seen work is a deal underwritten tight on acquisition cost where the sponsor points to their gc relationship as the reason construction risk is contained. The gc relationship does not hold when the draw schedule gets stressed and the sub pulls equipment.

What I keep trying to figure out from the outside, sitting in a small passive check position, is whether a $75k entry even gets you real visibility into a situation like the mechanical rough-in overrun before the sponsor has already decided how to handle it. Did they tell you about that overrun while it was happening, or did you find out in the quarterly update after they had already committed the solution?
