Multi-tenant medical office: the break-even math, in full

Executive answer

Splitting 125 Dillon Drive into 3–5 medical/professional suites is physically plausible, and the acquisition basis is the lowest in the node. The discipline this corridor asks for is pre-leasing: at realistic rents (~$12–14/SF NNN) the strategy wants roughly 85%+ occupancy to cover illustrative debt and operations, so anchor commitments belong in hand before closing. What makes it work: the cheapest basis in the node plus hospital adjacency. What to secure first: the tenants.

Why the idea exists

Small practices near hospitals often want 1,500–3,000 SF: too small to buy a building, too clinical for generic office parks. A landlord offering finished medical suites at sub-Class-A rents adjacent to a 231-bed campus serves a real niche; the county's provider base must grow with its population (growth research). The statute even allows a subdivided building site to earn the abandoned-buildings credit per parcel (§12-67-120(1) analysis), if eligibility is ever documented.

What the corridor shows today

The subject: marketed ~6 months for sale or lease at the submarket's lowest quoted rate, the pricing room a new owner inherits.
130 Dillon Dr: finished medical space asking $20/SF across the street, the reference point for what delivered suites command.
200 Dillon Cir: a $7.95/SF listing marks the corridor's value floor.
1650 Skylyn (Hugh R. Black Pavilion): ~109,500 SF of Class A on-campus space leasing now, the prestige option for any provider who can pay for it.
Test-fit first: the curved core and rotunda are distinctive; have an architect draw a suite plan before underwriting rentable SF, since no floor plan is published.

Scenario table (illustrative; all inputs editable in the underwriter)

Assumptions common to all: $775,000 purchase; subdivision/TI budget $35/SF ($350,000); 25% down on the $1,125,000 all-in; 7.5%, 25-yr amortization → annual debt service ≈ $74,800; operating expenses $4.50/SF on occupied space recovered via NNN, plus $1.50/SF unrecovered owner costs and reserves ≈ $15,000/yr; rentable 10,000 SF.

Scenario	Rent (NNN)	Occupancy	NOI	DSCR	Reading
Conservative	$11	70%	~$62,000	0.83	below debt coverage; shows why pre-leasing and equity sizing matter
Base	$13	85%	~$95,500	1.28	covers debt with a thin margin; value at an 8% cap ≈ $1.19M, barely above all-in
Upside	$15	95%	~$127,500	1.70	value at 7.75% cap ≈ $1.65M: real value creation where delivered suites earn $15 rents

Break-even occupancy at $13/SF NNN ≈ 84% (occupancy where NOI = debt service; formula: (debt service + unrecovered costs) ÷ (SF × rent)). At $11 rents, break-even exceeds 100%, so the plan should deliver finished suites that command $13+. Fund the lease-up period in the capital plan: a year at 50% occupancy carries ~$40k of cash cost.

What would have to be true

Two anchor tenants (3,000–4,000 SF combined) committed before or at closing, not after.
A floor plan that subdivides the curved core without a punitive loss factor (get a test-fit drawn).
Achieved rents ≥ $13/SF NNN, above the subject's current $10 ask, justified by delivered finished suites rather than shell.
A capital plan that funds 18–24 months of lease-up.

Regulation, staffing, capital

Landlord model: no facility licensure; ordinary permits. Staffing is the tenants' problem, though the same provider scarcity that creates tenant demand also slows tenant formation. Capital: acquisition + subdivision + TI + carry ≈ $1.1–1.3M all-in before leasing costs; leasing commissions and free-rent concessions belong in any serious model.

Why 125 Dillon Drive enters the candidate set

For an investor who believes the corridor absorbs medical suites, this is the cheapest building in the node to execute on, with the statutory subdivision quirk of the rehabilitation credit as unpriced upside. "Conditional" means the tenants come first: with an anchor commitment in hand, the lowest basis in the node is a strong position.

What would change this reading (in either direction)

To watch: corridor absorption through 2026; the test-fit's loss factor; renovation above $35/SF.
Upside triggers: a pre-leasing anchor (e.g., a hospital-affiliated group needing overflow space) would transform the risk profile overnight; so would documented credit eligibility funding the TI budget.
