Comparables · asking ≠ closed ≠ appraised

Medical-office comparables near the Mary Black corridor

Most "comps" pages blur three different kinds of numbers. We keep them separate: what sellers ask, what buyers actually paid, and what the county appraises — because conflating them is how bad underwriting starts.

Table 1 — Active asking prices (seller opinions, not evidence of value)

PropertyAskSF$/SFCondition/occupancy
130 Dillon Dr (Lee & Associates listing)$1,810,0007,200~$251partially leased medical (ortho + family practice); 4,015 SF also for lease at $20/SF
125 Dillon Dr (subject)$775,000±10,000~$77.50vacant; mid-renovation (core at studs)

Table 2 — Closed sales (the only market evidence)

PropertyClosedLast askClosed priceNotes
1770 Skylyn Dr — vacant ~9,594 SF former medical office, two blocks from subjectDec 19, 2025 (deed DEE-2025-57825, buyer TARVI LLC)$825,000 (~$86/SF)undisclosedclosest analog to the subject: similar size, similar vintage (1982), vacant at sale. Deed transfer stamps at the Register of Deeds would reveal the price — flagged as a diligence step.

We found no other disclosed 2025–2026 closed office/medical sales in this corridor. One closed comp is thin evidence — we say so rather than manufacture confidence.

Table 3 — County appraisals (context only; appraisal ≠ market value)

PropertyCounty appraised (land + building)County classification
125 Dillon Dr$804,900MED OFFICE, grade A, condition FAIR (1985)
130 Dillon Dr$472,500MED OFFICE, grade C, FAIR (1983)
200 Dillon Cir$750,000MED OFFICE building, grade C (1987)
1770 Skylyn Dr$760,000GEN OFFICE, grade C+, AVERAGE (1982)

Two things stand out. First, the subject is asking below its own county appraisal. Second, 130 Dillon asks nearly 4× its county appraisal — a reminder that neither appraisals nor asks are value; tenancy is.

What the spread means

In this corridor, vacant value-add medical product prices around $77–86/SF (subject ask; 1770 Skylyn ask-then-sale), while stabilized, tenanted product asks ~$251/SF (130 Dillon) against a ~$184/SF citywide medical average and a $147.90/SF regional all-office average sale price. The ~$100–170/SF gap between vacant and stabilized is the corridor's price for renovation risk and lease-up risk. Whoever closes that gap earns it — it is not free.

What could make this analysis wrong

  • One closed comp with an undisclosed price anchors the "vacant analog" tier — if 1770 Skylyn closed far below ask, the subject's ask is less supported than it looks.
  • Asking-price anchoring: 130 Dillon may never trade near $251/SF.
  • The subject's SF discrepancy (10,000 vs 10,896) moves its $/SF by ~8%.
  • County appraisals lag renovations and market shifts by design.

Continue: the investment thesis puts these numbers in context; the underwriter lets you test what renovation budget the spread actually supports; the subject's verified record is at /property/.
